All twelve rose Monday; Intel and Meta led, while early Tuesday indications were mixed.

Reuters reported on 18 September that Robinhood, Coinbase and Strategy rallied as bitcoin rose. Robinhood closed Friday up 9.12%.

Major Friday move; Crypto-linked shares rally

Friday close $119.82, +9.12%
Friday range $111.06-$120.57
Volume 39.22m; feed average 24.54m; 160% of average
Monday premarket +3.49%; feed timestamp 2026-09-21 04:38 EDT
Close 22.12% below the feed's 52-week high

Why it mattersCrypto trading activity can support transaction revenue, but a stock-price jump does not measure customer volumes or earnings. The 17 September tokenization announcement is earlier context, not a new Friday approval of a Robinhood product.

Intel fell 0.18% on Friday 18 September. Earlier context remains the 16 September report of SK Hynix cooperation talks and its 17 September statement that nothing company-specific had been finalized.

Minor Friday move; Early Monday rise; agreement still unverified

Friday close $108.60, -0.18%
Friday range $106.40-$110.49
Volume 174.68m; feed average 114.45m; 153% of average
Monday premarket +5.43%; feed timestamp 2026-09-21 04:54 EDT
Close 23.71% below the feed's 52-week high

Why it mattersThe early Monday quote shows a price increase, not proof of a signed agreement. The separate 18 September report about Solidigm considering a US NAND factory must not be relabeled as an Intel order.

Marvell announced its ECOC technology demonstrations on 21 September, including 2nm optical technologies for AI data-center connectivity. The program includes 400G-per-lane optical PAM4 and coherent optical technology demonstrations.

Notable Friday move; Monday optical technology demonstrations

Friday close $244.25, +1.45%
Friday range $235.96-$244.44
Volume 23.55m; feed average 19.19m; 123% of average
Monday premarket +2.60%; feed timestamp 2026-09-21 04:59 EDT
Close 25.96% below the feed's 52-week high

Why it mattersThis is a fresh Monday product-technology event. Demonstrations can help customer evaluation but are not purchase orders, shipments or revised revenue guidance. The 17 September GlobalFoundries capacity agreement is a separate, earlier development.

On 18 September Meta disputed a report about fraudulent advertisements in Poland and described its anti-scam controls. It said verification would be required of all financial-services advertisers targeting Poland.

Notable Friday move; Company responds on fraudulent advertising

Friday close $665.75, -2.43%
Friday range $660.80-$690.15
Volume 27.55m; feed average 20.88m; 132% of average
Monday premarket +2.44%; feed timestamp 2026-09-21 04:58 EDT
Close 15.81% below the feed's 52-week high

Why it mattersThese are company statements, not independently established findings about the disputed report. Advertising integrity matters to trust and compliance costs, but this response supplies no quantified earnings revision and does not establish the cause of Friday's decline.

Reuters reported on 17 September that Nebius will raise pay-as-you-go prices for selected Nvidia GPUs by 17%-21% from 1 October. Some CPU-only instances rise 25% and memory offerings about 41%; longer commitments can receive discounts.

Notable Friday move; September 17 pricing remains context

Friday close $223.54, +2.55%
Friday range $210.30-$224.65
Volume 21.28m; feed average 16.76m; 127% of average
Monday premarket +2.00%; feed timestamp 2026-09-21 04:05 EDT
Close 25.45% below the feed's 52-week high

Why it mattersThe 17 September pricing announcement is prior context for Friday trading, not a new Friday contract. Higher rental prices could improve revenue per chip if utilization holds, but discounts, hardware mix and costs affect realized margins.

The Register reported on 18 September that former Labour deputy leader Tom Watson had joined Palantir as a UK senior vice president. The appointment comes amid scrutiny of its NHS data-platform work.

Minor Friday move; UK leadership appointment

Friday close $177.64, +0.79%
Friday range $172.00-$177.75
Volume 39.23m; feed average 25.40m; 154% of average
Friday after-hours +0.14%; Monday premarket unavailable; feed timestamp 2026-09-18 19:59 EDT
Close 14.40% below the feed's 52-week high

Why it mattersThe hire may help government relationships, but it is not a new contract award or evidence that the existing NHS contract has been cancelled. Friday evening trading must not be mistaken for Monday premarket.

Reuters reported on 18 September that six auto-industry groups representing Tesla and other manufacturers urged President Trump to keep Chinese automakers out of the US market ahead of the expected meeting with Xi Jinping.

Minor Friday move; Industry trade-policy letter

Friday close $364.27, -0.53%
Friday range $360.75-$370.90
Volume 51.82m; feed average 39.42m; 131% of average
Monday premarket +1.39%; feed timestamp 2026-09-21 04:56 EDT
Close 26.98% below the feed's 52-week high

Why it mattersThis is a collective industry request, not a Tesla-only announcement or a new enacted restriction. Trade policy affects competition and supply chains, but the letter does not quantify Tesla demand or earnings.

Apple's store-arrival update says iPhone 18 Pro, Apple Watch Series 12, Apple Watch Ultra 4 and AirPods 5 became available on Friday 18 September. The page carries a 17 September update label, but explicitly dates the retail event to 18 September.

Minor Friday move; New devices become available Friday

Friday close $336.13, -0.26%
Friday range $332.53-$338.49
Volume 86.43m; feed average 49.16m; 176% of average
Monday premarket -0.23%; feed timestamp 2026-09-21 04:29 EDT
Close 2.45% below the feed's 52-week high

Why it mattersAvailability turns the launch into an actual sales opportunity, not proof of demand. Store photographs and marketing descriptions do not establish shipment volumes, a revenue beat or a change in margins.

Amazon's Whole Foods pay-and-benefits announcement was published on 10 September, although fresh press coverage appeared on 18 September. The company plans more than $230 million of investment, with hourly pay changes from 28 September and expanded benefits from 1 January 2027.

Notable Friday move; Whole Foods pay coverage revisits September 10

Friday close $253.71, +1.00%
Friday range $251.88-$255.43
Volume 52.15m; feed average 33.21m; 157% of average
Monday premarket +0.90%; feed timestamp 2026-09-21 04:06 EDT
Close 11.66% below the feed's 52-week high

Why it mattersThis is earlier news, not a new Friday spending commitment. Better compensation can support retention while adding costs; the announcement does not quantify the net operating-margin effect.

Nvidia rose on Friday 18 September, when Reuters described semiconductor strength supporting the market. Its 16 September benchmark and data-center announcements remain earlier context.

Notable Friday move; Friday chip-sector strength

Friday close $222.27, +1.34%
Friday range $218.03-$222.73
Volume 189.68m; feed average 113.69m; 167% of average
Monday premarket +0.82%; feed timestamp 2026-09-21 04:45 EDT
Close 6.03% below the feed's 52-week high

Why it mattersSector performance provides context but does not identify a unique company-specific cause. No fresh quantified financial outlook was identified in the Nvidia newsroom reviewed for this edition.

Reuters reported after the close on 17 September that newly unredacted court filings contained executive comments publishers say undermine Microsoft and OpenAI's fair-use defense. Microsoft said the testimony was consistent with its defense and did not settle the copyright questions before the court.

Minor Friday move; September 17 copyright report remains context

Friday close $493.78, -0.80%
Friday range $491.10-$498.65
Volume 39.54m; feed average 19.54m; 202% of average
Monday premarket +0.12%; feed timestamp 2026-09-21 04:50 EDT
Close 10.82% below the feed's 52-week high

Why it mattersThe report appeared after Thursday's close and was available for Friday trading. These are litigants' arguments, not an infringement judgment or damages award. The underlying filing was not read directly; the detail is attributed to Reuters.

Google announced additions to its AI & Economy research program on 18 September, including academic advisers and new research leadership studying adoption, productivity and labor-market effects.

Minor Friday move; AI economics research team expands

Friday close $349.54, +0.64%
Friday range $348.45-$359.44
Volume 47.53m; feed average 27.11m; 175% of average
Monday premarket +1.23%; feed timestamp 2026-09-21 04:23 EDT
Close 14.46% below the feed's 52-week high

Why it mattersThis is a dated research investment, not new advertising or cloud revenue guidance. It should not be conflated with the separate ad-tech remedy details disclosed on 16 September.

Thursday 17 September extended Intel's advance after the 16 September Reuters report of talks with SK Hynix about US memory production. Bloomberg reported on 17 September that SK Hynix said no company-specific cooperation or US production arrangement had been finalized.

Major Thursday move · Rally continues; talks are not a signed deal

Thursday range $104.70 to $111.37

Friday premarket unavailable from the historical feed request
Close 23.57% below the high over the fetched trailing 52-week window

Why it mattersA potential Ohio arrangement could improve infrastructure utilization, but the price move should not be mistaken for contracted revenue. Thursday coverage largely revisits Wednesday's negotiations; no signed agreement was verified.

On 17 September the SEC announced temporary conditional relief for certain tokenized-stock trading venues and liquidity providers. Reuters linked a rally in crypto-related shares, including Robinhood, to the announcement.

Major Thursday move · Tokenization relief supports the sector

Thursday close $109.81, +5.16%
Thursday range $106.08 to $110.55
Volume 21.85m; prior-20-session mean 24.15m; 90% of that mean
Friday premarket unavailable from the historical feed request
Close 28.63% below the high over the fetched trailing 52-week window

Why it mattersThe new framework may expand regulated onchain activity, but it is not blanket approval of every Robinhood product or a quantified earnings benefit. This is distinct from the 15 September allegations against two employees, which have not become findings of guilt.

GlobalFoundries and Marvell announced an expanded multi-year agreement on 17 September to increase silicon-germanium manufacturing capacity at Burlington, Vermont. The capacity supports optical interconnect products, including pluggable transceivers and near-packaged and co-packaged optics.

Major Thursday move · Optical connectivity capacity agreement

Thursday close $240.76, +4.81%
Thursday range $240.00 to $247.89
Volume 20.91m; prior-20-session mean 23.67m; 88% of that mean
Friday premarket unavailable from the historical feed request
Close 27.02% below the high over the fetched trailing 52-week window

Why it mattersSecuring manufacturing capacity reduces a potential supply constraint as AI systems need faster links between processors. The announcement does not disclose a contract value or revise Marvell's revenue outlook; manufacturing availability is not the same as realized customer demand.

Reuters reported on 17 September that Nebius will raise pay-as-you-go prices for selected Nvidia GPUs by 17%-21% from 1 October. Some CPU-only instances rise 25% and memory offerings about 41%; longer commitments can receive discounts.

Major Thursday move · Higher AI cloud list prices from October

Friday premarket unavailable from the historical feed request
Close 27.30% below the high over the fetched trailing 52-week window

Why it mattersHigher realized rental prices could improve revenue per deployed chip if utilization holds. List-price changes are not equivalent to the same percentage increase in company revenue: hardware mix, customer discounts, operating costs and occupancy all matter. This is fresh pricing news, not a relabeling of the 8 September Palantir partnership.

The US Army announced a $48,094,071 firm-fixed-price delivery order to Palantir USG on 17 September for ammunition-management software replacing nine legacy systems. The award has a 12-month base period and up to five optional years.

Notable Thursday move · Army awards ammunition software order

Friday premarket unavailable from the historical feed request
Close 15.07% below the high over the fetched trailing 52-week window

Why it mattersThis is a quantified new delivery order, not an open-ended partnership announcement. Implementation supports the defense software pipeline, but optional years are not guaranteed purchases and the award is not immediate recognized revenue.

Forum Mobility announced four planned California charging depots on 17 September, adding 30 MW of heavy-duty capacity. Tesla will operate public Megacharging at three sites: Ontario and two Oakland locations. Forum also reported reservations for more than 330 Tesla Semis.

Friday premarket unavailable from the historical feed request
Close 26.59% below the high over the fetched trailing 52-week window

Why it mattersCharging coverage can reduce an adoption barrier for electric trucks and support fleet utilization. The announced capacity is planned rather than fully operational, and reservations should not be counted as delivered trucks or recognized Tesla revenue.

AWS announced ready-to-use energy and utilities workflows for Amazon Quick on 17 September. Integrations from industry partners aim to connect business data for tasks such as grid planning, asset management and drilling exploration.

Notable Thursday move · AWS adds energy-sector AI workflows

Thursday close $251.19, +2.13%
Thursday range $249.24 to $252.73

Friday premarket unavailable from the historical feed request
Close 12.54% below the high over the fetched trailing 52-week window

Why it mattersIndustry-specific software can deepen enterprise usage of AWS, but this release provides no quantified sales commitment. The 16 September operations-pay increase and Generac generator agreement remain earlier context, not new Thursday announcements.

Reuters reported after the close on 17 September that newly unredacted court filings contained executive comments publishers say undermine Microsoft and OpenAI's fair-use defense. Microsoft said the testimony was consistent with its defense and did not settle the copyright questions before the court.

Notable Thursday move · Newly public copyright-case material

Friday premarket unavailable from the historical feed request
Close 10.11% below the high over the fetched trailing 52-week window

Why it mattersThis is litigation evidence and opposing parties' argument, not a new infringement judgment or damages award. It adds uncertainty around licensing economics, but the after-close report cannot be presented as the demonstrated cause of Thursday's regular-session gain. The filing was not read directly.

DOJ's 16 September announcement details ad-tech remedies including interoperability with competing tools, publisher data access, non-discriminatory bidding and monitoring. The detailed opinion was unsealed on 16 September; the earlier decision rejecting a breakup was on 2 September.

Notable Thursday move · Ad-tech remedy details, not a fresh breakup ruling

Thursday close $347.33, +1.30%
Thursday range $343.89 to $349.50

Friday premarket unavailable from the historical feed request
Close 15.00% below the high over the fetched trailing 52-week window

Why it mattersThe operating restrictions may make it easier for publishers to switch providers and can add compliance costs. Avoiding a breakup does not mean there is no business impact. These are Wednesday disclosures discussed on Thursday, not a new 17 September judgment.

Apple's store-arrival update says iPhone 18 Pro, Apple Watch Series 12, Apple Watch Ultra 4 and AirPods 5 became available on Friday 18 September. The page carries a 17 September update label, but explicitly dates the retail event to 18 September.

Nvidia participated in Thursday's semiconductor rally. Its company newsroom lists a 17 September GeForce NOW gaming update, while the Vera Rubin MLPerf Inference benchmark preview and flexible-data-center alliance remain dated 16 September.

Notable Thursday move · Chip rebound with prior benchmark context

Thursday close $219.34, +2.54%
Thursday range $217.15 to $219.91
Volume 93.96m; prior-20-session mean 129.94m; 72% of that mean
Friday premarket unavailable from the historical feed request
Close 7.27% below the high over the fetched trailing 52-week window

Why it mattersThe prior benchmark release supports the product-performance narrative, but it is not a new Thursday order or revenue revision. Sector strength and easing market yields are context; the reviewed sources do not isolate a single cause for Nvidia's daily return.

The reviewed Meta newsroom still lists the 16 September Threads podcast toolkit and the Meta One launch dated 15 September, updated 16 September. No new quantified 17 September company outlook was identified in those sources.

Notable Thursday move · Gain without a new financial announcement

Thursday close $682.31, +1.34%
Thursday range $667.05 to $683.20

Friday premarket unavailable from the historical feed request
Close 13.72% below the high over the fetched trailing 52-week window

Why it mattersProduct engagement and subscription conversion remain relevant, but a positive stock session does not establish an earnings upgrade. Earlier launch coverage retains its original event date rather than being counted as fresh Thursday news.

Robinhood fell 5.46% Wednesday. The DOJ announcement is dated 15 September: two engineers were charged with allegedly trading cryptocurrency futures using confidential listing information. Wednesday coverage revisited those charges alongside the prior day's stalled crypto legislation.

Major Wednesday move · Fraud allegations and crypto-policy uncertainty

Wednesday close $104.42, -5.46%
Session range $101.70 to $111.05, 9.19% low to high
Volume 33.49m against 25.26m average, 133% of average

Closed 32.13% below its 52-week high

Why it mattersThe allegations concern individuals, not a finding that Robinhood committed fraud. DOJ thanked the company for cooperating; the defendants are presumed innocent. Potential damage to trust and compliance costs is distinct from a demonstrated loss of customer assets or revenue.

Nebius gained 0.96% Wednesday and indicated an 11.05% rise at 07:03 ET Thursday. No new company release explaining that Thursday jump was identified in the sources reviewed. The newsroom still leads with the Palantir partnership announced on 8 September.

Minor Wednesday move · Large provisional premarket rise

Wednesday close $209.37, +0.96%
Session range $208.46 to $220.40, 5.73% low to high
Volume 13.36m against 13.65m average, 98% of average
Thursday premarket +11.05% at $232.50; 2026-09-17 07:03 EDT
Closed 30.18% below its 52-week high

Why it mattersThe move is a price observation, not evidence of a newly signed contract. AI cloud capacity remains sensitive to financing costs, power availability and customer utilization. The 8 September partnership is prior context and must not be counted again as fresh revenue.

Intel rose 4.03% Wednesday after Reuters reported on 16 September that SK Hynix was discussing US memory production with Intel, potentially using part of its Ohio facility. SK Hynix said no decision had been made.

Major Wednesday move · Reported US memory-production talks

Wednesday close $101.05, +4.03%
Session range $99.29 to $104.42, 5.17% low to high
Volume 119.11m against 96.07m average, 124% of average
Thursday premarket +2.92% at $104.00; 2026-09-17 07:01 EDT
Closed 29.01% below its 52-week high

Why it mattersA lease or partnership could improve the economics of idle or planned infrastructure. No signed transaction, price or production timetable was disclosed, so the market is valuing a possibility rather than committed earnings.

Marvell rose 3.61% Wednesday during the 15-17 September AI Infra Summit. Its event programme includes inference and connectivity presentations; the underlying summit release was dated 9 September. No fresh financial outlook was identified in the reviewed programme.

Major Wednesday move · Connectivity rebound during the summit

Closed 30.37% below its 52-week high

Why it mattersInference infrastructure demand supports the business case for optical links, networking and memory connectivity. A product demonstration is not a booked order, and the share-price recovery alone does not establish a change in expected sales.

On 16 September Amazon announced more than $1.5 billion of investment in higher US operations pay: eligible employees receive a $1 hourly increase, with minimum starting pay of $20 and average pay near $24. The increase takes effect 27 September, according to AP.

Minor Wednesday move · Higher workforce pay and data-center investment

Wednesday close $245.96, -0.99%
Session range $244.30 to $249.26, 2.03% low to high
Volume 33.32m against 30.03m average, 111% of average
Thursday premarket +1.39% at $249.39; 2026-09-17 06:50 EDT
Closed 14.36% below its 52-week high

Why it mattersHigher pay raises operating costs before any offset from retention, productivity or sales. Separately, Dow Jones reported a $2.4 billion Generac backup-generator agreement on 16 September, reinforcing the scale of data-center investment. The underlying filing could not be read directly. Neither announcement by itself establishes an earnings revision.

Microsoft fell 1.37% Wednesday despite its 15 September announcement of a $0.98 quarterly dividend, up $0.07 or 8%. It is payable 10 December to holders of record on 19 November; the ex-dividend date is also 19 November.

Notable Wednesday move · Dividend increase is dated Tuesday

Wednesday close $490.30, -1.37%
Session range $487.23 to $495.97, 1.79% low to high
Volume 16.61m against 17.74m average, 94% of average
Thursday premarket +0.96% at $495.00; 2026-09-17 06:30 EDT
Closed 11.45% below its 52-week high

Why it mattersThe increase is a concrete capital-return decision, but it is not a Wednesday earnings upgrade. A larger cash distribution does not remove sensitivity to higher discount rates or the capital costs of AI infrastructure.

Nvidia published its Vera Rubin NVL72 MLPerf Inference v6.1 preview on 16 September, reporting up to 3.7 times the throughput of GB300 NVL72 in the highlighted comparison. This is a company-reported benchmark result, not a customer revenue figure.

Minor Wednesday move · Vera Rubin benchmark preview

Wednesday close $213.90, +0.82%
Session range $212.50 to $216.76, 2.00% low to high

Thursday premarket +1.43% at $216.95; 2026-09-17 06:59 EDT
Closed 9.57% below its 52-week high

Why it mattersBetter inference throughput can strengthen customer economics and demand for new systems. The eventual financial benefit still depends on price, deployment costs, availability and actual utilization; the benchmark maximum is not a universal workload result.

On 16 September Google announced expanded agentic-commerce tools, including Merchant Center AI performance insights, a Business Agent beta for YouTube ads, and simpler integration of its Universal Commerce Protocol.

Minor Wednesday move · AI shopping tools expand

Wednesday close $342.87, -0.61%
Session range $340.64 to $348.40, 2.28% low to high

Thursday premarket +1.50% at $348.00; 2026-09-17 05:55 EDT
Closed 16.09% below its 52-week high

Why it mattersThe products aim to preserve discovery and checkout activity within Google as shopping becomes more conversational. Revenue depends on merchant adoption and conversion; the announcement supplies no quantified incremental advertising earnings.

Meta announced new Threads podcast tools on 16 September, including episode cards, reminders and audience insights. Meta One was introduced on 15 September; an updated article date does not make that subscription launch a second new event.

Minor Wednesday move · Threads adds podcast tools

Wednesday close $673.31, +0.46%
Session range $671.91 to $685.31, 1.99% low to high
Volume 17.17m against 20.15m average, 85% of average
Thursday premarket +0.99% at $680.00; 2026-09-17 07:01 EDT
Closed 14.86% below its 52-week high

Why it mattersThe Threads tools may support engagement and creator retention but include no revenue guidance. For Meta One, the reported 15 million figure combines subscriptions and trials, so it cannot be treated as a paid-subscriber count.

Palantir gained 1.03% Wednesday. The 8 September Nebius partnership remains prior context; no newly quantified 16 September contract or financial outlook was identified in the reviewed sources.

Notable Wednesday move · Software gain without a new quantified contract

Wednesday close $174.34, +1.03%
Session range $168.96 to $174.76, 3.44% low to high
Volume 20.90m against 26.89m average, 78% of average

Closed 15.99% below its 52-week high

Why it mattersThe partnership may widen sovereign AI deployment options, but it includes no minimum purchase commitment that can be turned directly into revenue. Wednesday's positive return does not establish a new operating catalyst.

Tesla gained 0.42% Wednesday. Reuters' 15 September report on NHTSA questions about Cybercab certification remains relevant, with responses due 30 September. No new financial guidance was identified in the reviewed 16 September reporting.

Minor Wednesday move · Cybercab regulatory deadline remains ahead

Wednesday close $358.08, +0.42%

Closed 28.22% below its 52-week high

Why it mattersHigher borrowing costs can weigh on vehicle affordability, while autonomy valuation depends on deployment and regulatory progress. The earlier information request is not an announced recall or operating ban and should not be relabeled as a new Wednesday action.

Apple gained 0.32% Wednesday. Its 16 September newsroom item showcased iPhone 18 Pro photography; it did not supply sales or financial guidance. The previously announced 18 September product availability remains the next near-term milestone.

Thursday premarket +0.55% at $334.25; 2026-09-17 06:29 EDT
Closed 3.53% below its 52-week high

Why it mattersMarketing ahead of availability is not evidence of actual unit demand. Upgrade conversion, product mix and margins will determine the financial effect of the new devices and the 14 September software rollout.

On 15 September, Senate Democrats blocked advancement of cryptocurrency legislation, according to AP. This is a regulatory setback rather than a new Robinhood operating result.

Wednesday premarket +0.19% at $110.66; timestamp 2026-09-16 09:17 EDT
Close was 28.21% below the 52-week high

Why it mattersA delayed regulatory framework keeps uncertainty around crypto products and transaction activity. The stock reaction does not itself measure a change in trading revenue.

Reuters reported on 16 September that SK Hynix is discussing US memory-chip production with Intel. Leasing part of the Ohio facility is one option; SK Hynix said no decision has been made.

Why it mattersA lease could help monetize infrastructure and spread fixed costs. These are reported negotiations, with no signed deal, disclosed economics or confirmed production timetable.

On 15 September, Meta introduced Meta One and reported 15 million subscriptions and trials combined. Core and Premium plans are listed at $7.99 and $19.99 monthly, with regional variation.

Minor Tuesday move · Meta One subscription launch

Wednesday premarket +0.96% at $676.65; timestamp 2026-09-16 09:15 EDT
Close was 15.25% below the 52-week high

Why it mattersSubscriptions can diversify revenue beyond advertising, but trials are not paying subscribers. Without the paid share, retention and service costs, the announcement cannot support a reliable profit estimate.

Reuters reported on 15 September that NHTSA ordered Tesla to answer Cybercab certification questions by 30 September, including how temporary human controls satisfy existing standards.

Minor Tuesday move · Cybercab certification questions

Close was 28.52% below the 52-week high

Why it mattersThe request adds execution uncertainty to autonomous deployment. It is not an announced recall or operating ban; the financial consequence depends on any required design or launch changes.

The Palantir partnership was announced on 8 September and names Nebius a preferred sovereign AI infrastructure partner. The newsroom review did not identify a fresh 15 September financial announcement.

Notable Tuesday move · Earlier Palantir agreement remains context

Close was 30.84% below the 52-week high

Why it mattersCustomer access can support future infrastructure utilization, but integration and actual consumption determine revenue. The prior agreement should not be counted again as a new order today.

AWS and Cognition announced a multiyear collaboration on 15 September covering autonomous engineering and enterprise modernization. Devin is available through AWS Marketplace.

Notable Tuesday move · AWS expands enterprise distribution

Tuesday close $248.42, -2.02%

Wednesday premarket +0.14% at $248.76; timestamp 2026-09-16 09:11 EDT
Close was 13.50% below the 52-week high

Why it mattersThe collaboration could expand cloud consumption and distribution, but the announcement does not disclose contract value or minimum spending. It cannot be converted directly into incremental AWS revenue.

Microsoft said on 15 September that LinkedIn presented arguments in the Fourth Circuit over government data requests and secrecy requirements. No new financial penalty was quantified in that update.

Notable Tuesday move · LinkedIn privacy case

Close was 10.22% below the 52-week high

Why it mattersThe issue concerns customer trust and legal access to data. The available disclosure does not establish a measurable change to Microsoft earnings or cloud demand.

Marvell is participating in the 15-17 September AI Infra Summit. Its programme lists an AI inference presentation on 16 September; the underlying event announcement was dated 9 September.

Notable Tuesday move · AI infrastructure summit continues

Close was 32.79% below the 52-week high

Why it mattersConnectivity and inference infrastructure remain central to the business. Event demonstrations are not booked revenue, and no revised outlook was identified in the reviewed event material.

On 15 September, Google announced Gemini in Workspace integrations with business tools including Asana, Salesforce and HubSpot, with administrator controls.

Notable Tuesday move · Workspace adds business-tool integrations

Tuesday close $344.98, -1.26%

Wednesday premarket +0.19% at $345.63; timestamp 2026-09-16 09:04 EDT
Close was 15.57% below the 52-week high

Why it mattersBroader workflow access may support enterprise adoption and retention. Google supplied no incremental revenue or margin forecast in this product update.

Nvidia announced CUDA-Q Logical on 14 September to support development of fault-tolerant quantum applications. It is a software ecosystem announcement, not a newly reported Tuesday chip order.

Minor Tuesday move · CUDA-Q platform expanded on Monday

Tuesday close $212.17, +0.57%
Session range $211.16 to $213.94
Volume 87.73m against a 115.76m average, 76% of average

Close was 10.30% below the 52-week high

Why it mattersTools can strengthen the surrounding computing ecosystem, but the release does not quantify near-term revenue. Tuesday price action alone does not establish a change to AI accelerator demand.

Apple released Siri AI and its major software-platform updates on 14 September. The initial Siri AI rollout includes language and regional restrictions. This is earlier product news, not a new Tuesday earnings disclosure.

Minor Tuesday move · Software rollout is dated 14 September

Tuesday close $331.34, -0.52%
Session range $328.35 to $331.78

Close was 3.84% below the 52-week high

Why it mattersMore capable software may support device engagement and upgrades. Adoption, paid conversion and delivery costs still determine the eventual financial return.

Palantir and Nebius announced their sovereign AI partnership on 8 September. It remains relevant background, but it is not a fresh 15 September contract award. No newly quantified Tuesday catalyst was identified in the reviewed sources.

Minor Tuesday move · Sovereign AI partnership remains prior context

Tuesday close $172.56, -0.43%
Session range $169.45 to $176.59
Volume 31.20m against a 27.25m average, 114% of average
Wednesday premarket -0.71% at $171.34; timestamp 2026-09-16 09:16 EDT
Close was 16.85% below the 52-week high

Why it mattersThe integration may widen deployment options for customers with sovereignty requirements. The announcement supplies no minimum purchase commitment to turn directly into a revenue estimate.

Marvell fell 7.32% Monday as investors cut exposure to AI infrastructure after weekend calls to slow frontier-model development.

Major move · AI infrastructure sold off · summit begins today

Monday close $218.82, -7.32%

Closed 33.67% below its 52-week high of $329.88
Moved +1.39% from Monday's open
Marvell's AI Infra Summit programme runs 15-17 September
The 9 September event release listed connectivity, CXL memory and storage demonstrations but changed no financial guidance

Why it mattersMarvell's networking, optical, memory and custom-silicon businesses are direct beneficiaries of rapid AI data-center spending. The industry safety debate therefore pressed on the assumed timing of demand, while the summit offers the next company-specific readout. No order cancellation or guidance revision was announced.

Intel fell 5.59% Monday with the chip group, then rebounded 1.89% in Tuesday premarket trading.

Major move · chip sell-off · premarket rebound

Moved +1.43% from Monday's open
Intel's latest identified newsroom release remains the 8 September High-NA EUV collaboration with ASML
No new Intel revenue, shipment or foundry milestone was published on 14 September

Why it mattersIntel combines server demand with a capital-intensive foundry plan. Slower AI development can challenge expected capacity utilization, while a near-5% Treasury yield raises the cost of waiting for foundry returns. Tuesday's rebound is provisional and is not tied to a fresh operating disclosure.

Nebius fell 5.50% Monday after trading through a 7.58% low-to-high range, then slipped another 1.03% Tuesday premarket.

Major move · AI-cloud repricing · no guidance change

Monday close $212.19, -5.50%

Moved +3.52% from Monday's open
Nebius launched its AI Builder Program on 10 September
The 8 September Palantir partnership named Nebius a preferred sovereign AI infrastructure partner but disclosed no contract value or minimum spend

Why it mattersNebius is a capital-intensive AI cloud, so a slower model-development cadence can reduce expectations for near-term compute consumption. Its latest product and partnership releases did not alter guidance, making the move a broad demand and valuation repricing rather than a response to new company numbers.

Palantir rose 3.64% Monday as software names held up better than AI infrastructure, then fell 1.85% Tuesday premarket.

Notable gain · software diverged from infrastructure · premarket reversal

Monday close $173.31, +3.64%
Traded from $166.42 to $174.36, a 4.77% low-to-high range
Volume 29.11m shares against a 26.72m average, 109% of normal

Moved +2.13% from Monday's open
The latest identified product event remains AIPCon 11 on 10 September
The event presented customer deployments and model options but supplied no new company-wide financial outlook

Why it mattersPalantir sells software for deploying and governing AI rather than the underlying chips and data-center equipment. Monday's divergence fits that distinction, but Tuesday's provisional reversal shows the broader risk-off move remains relevant. No fresh contract value or guidance accompanied either move.

Nvidia fell 3.36% Monday and was the largest drag on the S&P 500 in AP's account. It then rose 0.66% Tuesday premarket.

Notable move · central AI-demand proxy · modest premarket rebound

Monday close $210.96, -3.36%
Traded from $208.93 to $212.77, a 1.84% low-to-high range

AP reported on 14 September that Nvidia fell as AI-industry leaders called for slower development
Nvidia's newsroom showed no company release after its 10 September local-AI update from IFA

Why it mattersNvidia is the clearest listed proxy for frontier-model compute spending, so a proposed slowdown affects the assumed timing of GPU demand even without a change to backlog or guidance. The premarket bounce is a price response, not a new operating update.

Alphabet rose 3.22% Monday as the market distinguished software platforms from the hardest-hit infrastructure names, then fell 1.38% Tuesday premarket.

Notable gain · platform and software resilience · premarket lower

Monday close $349.39, +3.22%
Traded from $342.14 to $349.91, a 2.27% low-to-high range

Closed 14.49% below its 52-week high of $408.61
Moved +1.83% from Monday's open
The latest identified product items remain the 10 September Gemini Windows app and Morgan State AI-campus collaboration
Those announcements disclosed no pricing, seat count or contract value

Why it mattersAlphabet owns both model development and distribution through Search, Cloud and Gemini. Monday's rise suggests investors differentiated that revenue base from hardware exposure, while the Tuesday decline reflects renewed broad pressure. No fresh company-wide financial update was found.

Meta rose 2.71% Monday despite the AI-safety debate, then traded 0.91% lower Tuesday premarket.

Notable gain · platform dispersion · premarket lower

Monday close $665.60, +2.71%
Traded from $649.22 to $668.60, a 2.99% low-to-high range

Closed 15.83% below its 52-week high of $790.80
Moved +1.18% from Monday's open
The latest Meta newsroom release remains the 8 September Muse launch
Meta has not disclosed paid conversion, revenue or inference economics for Muse

Why it mattersMeta combines AI spending with an advertising platform that already monetizes engagement. A slower frontier race could lower competitive capex intensity, but that is an inference rather than a disclosed plan. Tuesday's decline arrived without a new Meta operating release.

Microsoft rose 1.97% Monday, then traded 1.29% lower Tuesday premarket without a new company release.

Minor gain · diversified AI exposure · premarket lower

Monday close $505.41, +1.97%

Moved +1.68% from Monday's open
The latest identified policy item remains Microsoft's Safe Participation Framework dated 10 September
The framework described age-appropriate AI safeguards but attached no financial target

Why it mattersMicrosoft combines direct AI infrastructure exposure with recurring software revenue and a close OpenAI relationship. Monday's gain may reflect that diversification, but the later decline shows sensitivity to yields and AI demand expectations. No new Azure demand, capex or margin figure was published.

Tesla fell 1.77% Monday after Elon Musk supported the weekend call for slower AI development; its Tuesday premarket print was effectively unchanged.

Minor decline · AI-safety comments · premarket flat

Monday close $358.97, -1.77%
Traded from $357.04 to $367.73, a 2.99% low-to-high range
Volume 32.40m shares against a 43.64m average, 74% of normal

Closed 28.04% below its 52-week high of $498.83
Moved -0.23% from Monday's open
The latest identified operating events remain the 3 September Cybercab launch and the 4 September NHTSA investigation
Third-quarter deliveries remain due in early October

Why it mattersMusk's agreement is relevant to xAI and to the AI assumptions embedded in Tesla's autonomy narrative, but it was not a Tesla production, delivery or financial update. The settled decline therefore mixes broader growth-stock pressure with uncertainty about development pace.

Robinhood rose 1.56% Monday, then fell 2.20% Tuesday premarket.

Minor gain · August metrics still the latest operating read · premarket lower

Monday close $114.33, +1.56%

The 10 September August report showed 28.6m funded customers, $383.7bn of platform assets and $4.0bn of net deposits
Options contracts fell 10% and event contracts fell 23% from July, while crypto notional rose 61%

Why it mattersAugust data combined asset and customer growth with mixed transaction activity. Monday's gain and Tuesday's provisional decline supplied price responses but no new monthly metric. The premarket move also sits within a broader risk-off tape before the Fed decision.

Amazon fell 1.26% Monday and traded another 0.58% lower Tuesday premarket.

Minor decline · cloud exposure meets higher yields · premarket lower

Monday close $253.54, -1.26%

Moved +0.15% from Monday's open
Amazon's 14 September news feed added a Bedrock customer case study and Prime Video on-demand news clips
Neither item revised AWS growth, company guidance or capital spending

Why it mattersAWS benefits from sustained AI training and inference demand, so a slower development cadence can reduce expected incremental compute consumption. Higher Treasury yields also raise the hurdle for capital-intensive cloud investment. Monday's company posts supplied no financial counter-signal.

Apple edged up 0.24% Monday, then traded 0.62% lower Tuesday premarket as the new-device cycle moved from pre-orders toward availability.

Near flat · product cycle moves toward availability · premarket lower

iPhone 18 Pro pre-orders began on 12 September
iPhone 18 Pro, Apple Watch Series 12 and AirPods 5 become available on 18 September; AppleCare One Family began on 14 September

Why it mattersThe product cycle has entered the order window, but Apple has not published demand, unit or margin evidence. The small settled gain and later decline therefore provide market signals rather than a confirmed operating read.

Nebius posted the weakest premarket reading of the twelve at -7.82% Monday.

Major move · AI-infrastructure repricing · premarket provisional

Friday close $224.55, -1.56%

Friday's 1.56% fall was the largest settled decline of the twelve
The latest company release remains the 8 September Palantir partnership
That release named Nebius Palantir's preferred sovereign AI infrastructure partner but disclosed no contract value or minimum spend

Why it mattersNebius is building a capital-intensive AI cloud, so any slower model-development cadence can reduce expectations for near-term compute demand while higher oil and Treasury yields lift its financing and valuation hurdle. The move is not tied to a new Nebius contract cancellation or guidance change.

Marvell posted the second-weakest premarket reading of the twelve at -7.44% Monday.

Major move · Friday leader reversed by AI warning · premarket provisional

Friday's 4.03% rise was the largest settled gain of the twelve
The latest company blog was dated 10 September and demonstrated scalable CXL memory infrastructure with Intel
Marvell's AI Infra Summit programme runs 15-17 September

Why it mattersThe reversal directly targets Marvell's AI-data-center exposure: slower frontier-model development would challenge the timing of demand for networking, optical and memory infrastructure. There is no new order cancellation or guidance change, and the AI Infra Summit begins Tuesday.

Intel posted the third-weakest premarket reading of the twelve at -6.25% Monday.

Major move · Friday rebound reversed · premarket provisional

Friday's 2.61% rise was the second-largest settled gain of the twelve
Intel's latest newsroom release was the 8 September High-NA EUV collaboration with ASML
Monday's move is not a new price-change report or a revision to Intel guidance

Why it mattersIntel's valuation is exposed to both server demand and execution at a capital-intensive foundry. The weekend safety discussion changes the market's assumed pace of AI infrastructure demand, while the near-5% ten-year yield raises the cost of waiting for foundry returns. Intel issued no new weekend operating update.

Nvidia finished Friday effectively unchanged at -0.03%, then moved sharply lower before Monday's open.

Notable move · AI-demand duration questioned · premarket provisional

Friday's close was effectively flat despite a 1.76% intraday range
Nvidia's newsroom showed no company release dated after 10 September

Why it mattersNvidia is the clearest listed proxy for frontier-model compute spending, so calls to slow development affect the assumed timing of GPU demand even without a change to backlog or guidance. The $12.93bn Hugging Face agreement is an older 3 September event, not new weekend news.

Tesla gained 0.52% Friday and traded 1.57% lower Monday premarket after Elon Musk backed Dario Amodei's call for slower AI development.

Notable move · Musk backs AI-safety warning · premarket provisional

Tesla's latest identified operating events remain the 3 September Cybercab launch and the 4 September NHTSA investigation
Third-quarter deliveries remain due in early October

Why it mattersMusk's agreement is relevant to xAI and to the AI assumptions embedded in Tesla's autonomy narrative, but it was not a Tesla production, delivery or financial update. The premarket decline therefore mixes broader growth-stock pressure with uncertainty about AI development pace.

Amazon gained 1.94% Friday, the third-largest settled gain of the twelve.

The latest material operating announcements remain the 10 September expansion of Amazon Leo launch capacity and the Whole Foods pay-and-benefits investment
No new contract value or financial outlook was attached over the weekend

Why it mattersAWS benefits from sustained AI training and inference demand, so a slower development cadence can reduce the pace of incremental compute consumption. Amazon's 11 September press-center item was a $163,000 community-grant programme, not a material change to AWS, retail or guidance.

Apple gained 1.75% Friday as it issued a product-availability update before iPhone 18 Pro pre-orders opened Saturday, then added 0.51% Monday premarket.

Why it mattersThe dated update moves the product cycle from announcement to orders. That creates the first direct demand signal for the iPhone 18 Pro lineup, while the 18 September availability date starts the revenue-conversion window. Apple still has not published unit demand or margin evidence.

Alphabet gained 1.77% Friday and rose another 1.83% Monday premarket despite the earlier sell-off in AI-linked futures.

Notable gains · positive despite AI warning · premarket provisional

Friday close $338.50, +1.77%
Traded from $335.03 to $342.98, a 2.37% low-to-high range
Volume 24.68m shares against a 25.30m average, 98% of normal
Monday premarket +1.83% at $344.69, a provisional extended-hours print
Closed 17.16% below its 52-week high of $408.61
Moved +1.04% from Friday's open
The latest identified product items remain the 10 September Gemini Windows app and Morgan State AI-campus collaboration
Those announcements did not disclose pricing, seat count or contract value

Why it mattersAlphabet owns both model development and distribution through Search, Cloud and Gemini. The positive later print suggests investors are not treating a slower frontier race as uniformly negative for platforms with existing revenue and distribution, but no new weekend Google financial update supports a quantified change.

Meta gained 0.57% Friday and rose 1.85% Monday premarket, the largest positive premarket move of the twelve.

Notable premarket gain · platform dispersion · provisional

Friday close $648.03, +0.57%
Traded from $646.20 to $664.24, a 2.79% low-to-high range
Volume 16.91m shares against a 19.07m average, 89% of normal

Closed 18.05% below its 52-week high of $790.80
Moved -0.84% from Friday's open
The latest Meta newsroom release remains the 8 September Muse launch
Muse's core service is free and Meta has not disclosed paid conversion or inference economics

Why it mattersThe later positive print separates Meta from the early broad AI sell-off. A slower frontier race could reduce competitive capex intensity, but that is an inference rather than a disclosed plan. Meta published no new weekend adoption, revenue or cost figures for Muse.

Palantir gained 0.83% Friday and rose another 1.09% Monday premarket as its software exposure diverged from chip and infrastructure names.

Notable premarket gain · software diverges from chips · provisional

Friday close $167.23, +0.83%
Traded from $165.40 to $168.61, a 1.94% low-to-high range
Volume 15.38m shares against a 26.32m average, 58% of normal

Closed 19.41% below its 52-week high of $207.52
Moved -0.52% from Friday's open
The latest product announcements remain dated 10 September
AIPCon 11 presented customer deployments and model options but no new company-wide outlook

Why it mattersPalantir sells deployment and operating software rather than compute hardware. The positive print may reflect that difference, while its 10 September AIPCon still supplied no new contract value or guidance. The weekend debate does not change disclosed Palantir economics.

Robinhood fell 0.67% in Friday's full session after publishing August operating data Thursday evening; Twelve Data returned no current Monday premarket observation.

Minor decline · full-session response to August data · settled close

Friday close $112.57, -0.67%
Traded from $111.02 to $116.40, a 4.85% low-to-high range
Volume 19.66m shares against a 22.84m average, 86% of normal

Closed 26.84% below its 52-week high of $153.86
Moved -0.69% from Friday's open
The August report showed 28.6m funded customers, $384bn of platform assets and $4.0bn of net deposits
Options contracts fell 10% and event contracts fell 23% from July, while crypto notional rose 61%

Why it mattersFriday's settled decline is the cleaner response to a report that combined rising customers, assets and deposits with sequentially lower options and event-contract activity. The weekend AI discussion does not provide a direct new operating read-through for Robinhood.

Microsoft gained 0.65% Friday and added 0.58% Monday premarket without a new weekend company release.

Minor gains · safety framework already published · premarket provisional

Friday close $495.63, +0.65%
Traded from $492.58 to $498.97, a 1.30% low-to-high range

Moved -0.00% from Friday's open
The latest identified policy item remains Microsoft's 10 September Safe Participation Framework
The framework described age-appropriate AI safeguards but attached no financial target

Why it mattersMicrosoft combines direct AI infrastructure exposure with recurring software revenue and a close OpenAI relationship. Its positive later print may reflect that diversification, but the weekend discussion introduced no new Azure demand, capex or margin figures.

Apple gained 3.56%, the largest gain of the twelve, in the full session after its iPhone Duo and iPhone 18 Pro event.

Major move · post-event iPhone response · settled close

Close $326.57, +3.56% from $315.34
Traded from $316.51 to $326.74, a 3.23% low-to-high range
Volume 69.93m shares against a 44.71m average, 156% of normal
Premarket -0.21% at $325.89, a provisional extended-hours print
Closed 5.22% below its 52-week high of $344.57
It gained 3.13% from the open while QQQ fell 1.06%
Volume reached 156% of normal, the heaviest volume of the twelve
iPhone Duo starts at $1,999; pre-orders begin 16 October and availability begins 23 October

Why it mattersThursday supplied the positive follow-through that Wednesday's nearly flat event-day close did not. The $1,999 foldable can lift mix if demand holds, but the delayed order window means the move still precedes evidence on units, component cost and gross margin.

Intel fell 5.57%, the largest fall of the twelve, without a newly dated Thursday company announcement in the sources reviewed.

Major move · reversal without a fresh operating release · settled close

Close $100.32, -5.57% from $106.24
Traded from $99.34 to $103.23, a 3.92% low-to-high range
Volume 96.35m shares against a 89.85m average, 107% of normal
Premarket +1.19% at $101.51, a provisional extended-hours print
Closed 29.53% below its 52-week high of $142.35
It fell 2.08% from the open and finished below $101
The stock had gained 10.90% across Tuesday and Wednesday on a compounded basis
Premarket recovered 1.19% to $101.51

Why it mattersThe decline reverses part of a two-session surge that followed an unconfirmed report of another PC-CPU price increase. Intel supplied no Thursday update to confirm volume, timing or demand elasticity. Higher oil, producer inflation and Treasury yields supplied a common valuation headwind for chip shares.

Nebius fell 5.09%, the second-largest fall of the twelve, with no company release dated Thursday after the Palantir partnership and Citi appearance earlier in the week.

Major move · partnership premium unwound · settled close

Close $228.11, -5.09% from $240.35
Traded from $226.03 to $238.33, a 5.44% low-to-high range

Premarket +2.36% at $233.50, a provisional extended-hours print
Closed 23.93% below its 52-week high of $299.86
It fell 1.68% from the open across a 5.44% intraday range
Premarket recovered 2.36% to $233.50
The 8 September partnership named Nebius as Palantir's preferred sovereign AI infrastructure partner for eligible commercial customers

Why it mattersNebius combines rapid demand with a capital-intensive buildout, making a jump in long-term yields especially relevant to its valuation. The Palantir route to market remains strategically positive, but it still has no disclosed contract value, capacity commitment or minimum spend.

Marvell fell 3.43%, reversing much of Wednesday's 4.26% gain, without a new Thursday press release.

Major move · summit-release reversal · settled close

Close $226.96, -3.43% from $235.01
Traded from $226.15 to $234.49, a 3.69% low-to-high range

Premarket +0.98% at $229.18, a provisional extended-hours print
Closed 31.20% below its 52-week high of $329.88
Volume was 66% of normal, the lightest volume of the twelve
It closed 31.20% below its 52-week high, the largest gap of the twelve
Premarket recovered 0.98% to $229.18
The dated catalyst remains the 9 September AI Infra Summit portfolio announcement

Why it mattersThe prior release described switching, optical, memory and storage products but no new order or guidance. Thursday's reversal on light volume says the initial positioning premium was fragile, while Friday premarket is attempting a partial recovery ahead of next week's summit.

Nvidia fell 2.37% on the day of its Goldman Sachs conference appearance as chip shares absorbed the rise in oil and Treasury yields.

Notable move · conference day under macro pressure · settled close

Close $218.36, -2.37% from $223.67
Traded from $217.20 to $220.99, a 1.74% low-to-high range

Closed 7.69% below its 52-week high of $236.54
It fell 0.98% from the open
Premarket recovered 0.75% to $220.00
The previously announced Australian ecosystem target remains up to 2 GW by 2027

Why it mattersNo new guidance or contract value accompanied Thursday's investor event in the materials reviewed. The Australian capacity announcement remains an ecosystem target rather than a booked Nvidia order, so a 12-basis-point rise in the ten-year yield supplied the clearer common pressure on valuation.

Palantir fell 2.16% as AIPCon 11 showed deployments across aviation, defense, healthcare, manufacturing, media and insurance.

Notable move · AIPCon 11 product and customer evidence · market rejected

Close $165.86, -2.16% from $169.53
Traded from $164.55 to $169.00, a 2.70% low-to-high range
Volume 21.28m shares against a 28.85m average, 74% of normal
After-hours +0.39% at $166.50 at 19:59 ET; no current Friday premarket print was returned
Closed 20.08% below its 52-week high of $207.52
It fell 0.89% from the open
The 19:59 ET print was +0.39% after-hours; Twelve Data did not return a current Friday premarket observation
Presenting customers included Cisco, Eaton, the FAA, L3Harris, Novartis, Nvidia, Ondas Sentinel, USA TODAY and Zeta Global
AIP added Gemini 3.8 Flash and GPT-5.6 models on eligible enrollments, while Pipeline Builder evaluation suites became generally available

Why it mattersAIPCon supplied evidence that customers are deploying Palantir software in operating workflows, and the product updates broaden model choice and validation. The release gave no new contract value or guidance, and the negative close shows that deployment breadth did not overcome a higher discount rate.

Robinhood fell 1.69% before reporting mixed August operating data after Thursday's close, then traded 0.86% lower Friday premarket.

Notable move · August operating data after the close · mixed

Close $113.33, -1.69% from $115.28
Traded from $111.95 to $116.30, a 3.89% low-to-high range
Volume 16.38m shares against a 22.24m average, 74% of normal
Premarket -0.86% at $112.35, a provisional extended-hours print
Closed 26.34% below its 52-week high of $153.86
Funded customers reached 28.6m, up about 120,000 from July and 1.9m year over year
Platform assets reached $384bn, up 8% month over month and 26% year over year
August net deposits were $4.0bn, a 14% annualized rate relative to July assets
Equity notional rose 1% from July; options contracts fell 10%, event contracts fell 23% and crypto notional rose 61%

Why it mattersCustomer, asset and deposit growth support the asset-gathering story, while the sequential declines in options and event-contract activity reduce the read-through to transaction revenue. The negative premarket response indicates the mix mattered more than the headline asset gain.

Meta fell 1.42% without a new Thursday newsroom post, giving back part of Wednesday's 6.55% Muse rally.

Notable move · Muse gain partially unwound · settled close

Close $644.38, -1.42% from $653.69
Traded from $642.14 to $663.50, a 3.33% low-to-high range
Volume 21.49m shares against a 18.90m average, 114% of normal
Premarket +0.51% at $647.65, a provisional extended-hours print
Closed 18.52% below its 52-week high of $790.80
It fell 1.43% from the open
Volume remained above average at 114% of normal
Premarket recovered 0.51% to $647.65
Muse's core service is free, while Meta has not disclosed subscription pricing, adoption targets or inference cost

Why it mattersThe two-day pattern says investors retained part of the value assigned to a consumer agent but reduced the initial enthusiasm. Without pricing or usage economics, the valuation still rests on product optionality rather than a measurable earnings contribution.

Tesla fell 1.16% without a material company announcement dated 10 September in the sources reviewed.

Notable move · no newly dated operating catalyst · settled close

Close $363.56, -1.16% from $367.81
Traded from $357.68 to $369.21, a 3.22% low-to-high range

Premarket +0.12% at $364.00, a provisional extended-hours print
Closed 27.12% below its 52-week high of $498.83
It gained 0.82% from the open but remained below Wednesday's close
Premarket was +0.12% at $364.00
The latest identified operating events remain the 3 September Cybercab launch and the 4 September NHTSA investigation

Why it mattersWith no new operating disclosure, Thursday's decline belongs more convincingly to the broad risk-off tape than to a new Tesla-specific fact. The unresolved Cybercab investigation remains the next source of measurable operating information.

Alphabet gained 0.59% as Google launched the Gemini app for Windows and Google Public Sector announced an AI-campus collaboration with Morgan State University.

Minor move · Gemini Windows launch and education deployment · settled close

Close $332.60, +0.59% from $330.65

Closed 18.60% below its 52-week high of $408.61
It gained 1.33% from the open
Premarket added 0.43% to $334.04
The Windows app uses Alt + Space and can connect to Gmail and Drive for multi-step tasks
Morgan State will receive GPU compute through Google's Program for Accelerated Research, plus Google SecOps and Mandiant technology

Why it mattersA native Windows app widens Gemini's distribution beyond the browser, while the Morgan State deployment adds a public-sector reference customer across compute, security and training. Neither announcement disclosed price, seat count or contract value, so the close is positive product evidence rather than a revenue estimate.

Amazon fell 0.20% as it added six Ariane 6 launches for Amazon Leo and committed more than $230m to Whole Foods pay and benefits over the coming year.

Minor move · Leo launch capacity and Whole Foods investment · settled close

Close $251.89, -0.20% from $252.40
Traded from $249.58 to $253.15, a 1.43% low-to-high range

Closed 12.29% below its 52-week high of $287.20
It gained 0.71% from the open
Premarket added 0.77% to $253.82
The Arianespace commitment increases from 18 to 24 launches; the provider has placed 100 Leo satellites in orbit across three missions
Whole Foods' plan covers more than 100,000 US team members, with pay changes starting 28 September and Amazon benefits from 1 January 2027

Why it mattersThe additional launches increase the committed cost base but also reduce deployment bottlenecks before Leo's initial service rollout. The Whole Foods programme is a disclosed near-term expense intended to support retention and store execution. Neither release quantified a direct revenue offset.

Microsoft gained 0.16% as it published a Safe Participation Framework for privacy-preserving, age-appropriate AI and online services.

Minor move · youth AI safety framework · settled close

Close $492.44, +0.16% from $491.65
Traded from $486.00 to $494.52, a 1.75% low-to-high range

Closed 11.07% below its 52-week high of $553.72
It gained 0.84% from the open
Premarket added 0.20% to $493.44
The framework covers safety by design, age-differentiated experiences, and education and empowerment
Microsoft said Copilot users must sign in and access is restricted for children under 13, or older where local law requires

Why it mattersThe framework can reduce regulatory and trust friction around youth use, but it also commits Microsoft to continuing safeguards, age signals and education work. No customer, revenue or cost figure was attached, which fits the small price response.

Meta rose 6.55%, the largest gain of the twelve, in the first full cash session after its late-Tuesday launch of Muse.

Major move · first full-session Muse reaction · settled close

Close $653.69, +6.55% from $613.48
Traded from $638.56 to $657.86, a 3.02% low-to-high range

Premarket +1.42% at $663.00, a provisional extended-hours print
Closed 17.34% below its 52-week high of $790.80
Volume reached 180% of normal, the heaviest volume of the twelve
It gained 0.78% from the open and added +1.42% premarket
Muse runs in a dedicated Secure VM, works in WhatsApp and can use Stripe Link for purchases
The US rollout covers iOS, Android and muse.ai; core use is free with paid plans for more

Why it mattersMuse moves Meta from embedded chatbots toward an agent that can browse, fill forms, book travel and complete purchases. That expands the consumer product surface, but Meta disclosed neither user targets nor subscription pricing, revenue or inference cost. Wednesday's reaction therefore prices an option on adoption rather than a measured earnings contribution.

Marvell gained 4.26%, the second-largest gain of the twelve, as it detailed the connectivity and memory portfolio it will show at AI Infra Summit next week.

Major move · AI-connectivity product positioning · settled close

Close $235.01, +4.26% from $225.41
Traded from $223.60 to $241.88, a 8.18% low-to-high range
Volume 20.44m shares against a 24.93m average, 82% of normal
Premarket -1.45% at $231.60, a provisional extended-hours print
Closed 28.76% below its 52-week high of $329.88
It gained 5.01% from the open across an 8.18% range
The portfolio includes a 102 Tbps Ethernet switch and a 256-lane PCIe 6.0 switch
Marvell also listed Photonic Fabric, RELIANT telemetry, CXL memory and PCIe 6.0 NVMe storage
AI Infra Summit runs 15-17 September in Santa Clara

Why it mattersThe release puts Marvell across switch, optical, memory and storage links that determine accelerator utilization. It names products but no customer, order value or guidance increase. That makes the 4.26% move a strong vote on positioning rather than a response to newly quantified revenue.

Alphabet fell 2.28%, the largest fall of the twelve, as Google announced a minimum of EUR13bn of Finland digital and AI infrastructure investment for 2027-2028.

Notable move · €13bn Finland infrastructure plan · settled close

Close $330.65, -2.28% from $338.36
Traded from $327.90 to $331.85, a 1.20% low-to-high range

Premarket +0.01% at $330.67, a provisional extended-hours print
Closed 19.08% below its 52-week high of $408.61
The plan covers Hamina, Kajaani, Muhos and Vaala across 2027-2028
Volume was 133% of normal
Premarket is effectively flat at +0.01%

Why it mattersThe programme expands capacity in four Finnish locations and supports long-run AI supply, but it also adds a large capital commitment before the return is visible. Oil, higher yields and a lower QQQ provide a common negative backdrop, so the close cannot isolate how much of the fall belongs to spending concerns.

Amazon fell 1.78%, the second-largest decline of the twelve, despite announcing a Wiwynn server-rack manufacturing expansion in Socorro, Texas.

Notable move · Texas manufacturing expansion and air-crash update · settled close

Close $252.40, -1.78% from $256.97
Traded from $250.65 to $254.69, a 1.61% low-to-high range

Wiwynn said its investment in the facility exceeds $1.6bn
The partners expect nearly 1,000 new jobs by the end of 2027 and more than 2,500 workers next year
Amazon's 9 September update said the NTSB investigation continues and that 21 Air operated the flight

Why it mattersDomestic rack production can shorten supply chains for AWS, but the disclosed $1.6bn is Wiwynn's investment and the release gives no Amazon purchase commitment. Retailers also weakened as fuel costs rose, while Amazon updated its response to the 21 Air-operated fatal cargo crash. The close combines all three channels.

Robinhood fell 1.76% as CEO Vlad Tenev discussed prediction markets, crypto and product integration at Goldman Sachs.

Notable move · conference update, monthly metrics ahead · settled close

Closed 25.07% below its 52-week high of $153.86
Opened at $120.77 and fell 4.55% to the close
Tenev said sports is a wedge that can broaden use into more prediction-market categories
August monthly metrics are anticipated today at 16:05 ET

Why it mattersThe conference reiterated prediction markets as a customer-acquisition wedge and part of an active-trader stack, but it did not replace a reported monthly operating dataset. The shares fell 4.55% from the open, so investors did not reward the narrative ahead of August metrics due today.

Intel rose 1.69% without a newly dated Wednesday company announcement, extending Tuesday's 9.05% gain on a reported PC-CPU price increase.

Notable move · second-day response to unconfirmed report · settled close

Close $106.24, +1.69% from $104.47

Closed 25.37% below its 52-week high of $142.35
It gained 3.45% from its $102.70 open
The DigiTimes report is dated 8 September and points to an early-October change

Why it mattersA roughly 10% price increase can support gross margin if demand holds, but the report remains unconfirmed by Intel and does not quantify unit elasticity. Wednesday's smaller gain looks like follow-through rather than new evidence, and the stock is 1.32% lower premarket.

Nebius fell 1.45% after Palantir named it the preferred sovereign AI infrastructure partner for eligible commercial customers and its CEO spoke at Citi.

Notable move · Palantir partnership and Citi appearance · market rejected

Close $240.35, -1.45% from $243.88

It fell 3.05% from the open
The partners said Nebius endpoints will become available inside Palantir's enterprise perimeter after integration
The -2.64% move is the weakest premarket reading of the twelve

Why it mattersThe partnership creates a route for Nebius compute and inference inside Palantir's enterprise perimeter, but it discloses no contract value, capacity commitment or minimum spend. Management again described demand above supply. The stock's decline after Tuesday's 7.73% gain says investors did not add another premium for the new detail.

Nvidia fell 0.91% as it announced an Australian ecosystem buildout designed to host up to 2 GW of AI infrastructure by 2027.

Minor move · Australian ecosystem capacity announcement · market rejected

Close $223.67, -0.91% from $225.73
Traded from $223.46 to $226.18, a 1.22% low-to-high range
Volume 82.74m shares against a 154.12m average, 54% of normal
Premarket -0.30% at $223.00, a provisional extended-hours print

Partners named include Firmus, Sharon AI, IREN, Megaport, ResetData, CDC, NEXTDC and AirTrunk
The target is up to 2 GW by 2027
The close sits 5.44% below its 52-week high, the smallest gap of the twelve

Why it mattersThe release broadens land, power and shell capacity around Nvidia's DSX platform, but 'up to' 2 GW is an ecosystem target rather than an Nvidia order or recognised revenue. The negative close alongside higher yields suggests the strategic headline did not override macro pressure.

Microsoft fell 0.47% as it agreed with the AFT and UFT on a National AI Safety and Privacy Standard that school districts can add to Microsoft contracts.

Why it mattersThe standard may reduce adoption friction by making privacy protections enforceable, but it also adds contractual obligations and gives districts remedies. The release contains no customer count or revenue impact, so the stock's small decline is not evidence for either side of that trade-off.

Palantir fell 0.45% in the first full session after naming Nebius its preferred sovereign AI infrastructure partner.

Minor move · Nebius sovereign infrastructure partnership · market rejected

Close $169.53, -0.45% from $170.30
Traded from $168.61 to $171.86, a 1.93% low-to-high range
Volume 20.29m shares against a 29.50m average, 69% of normal
Premarket -0.31% at $169.00, a provisional extended-hours print
Closed 18.31% below its 52-week high of $207.52
It fell 1.13% from the open
The companies said eligible customers will access Nebius cloud and inference endpoints after integration

Why it mattersEmbedding Nebius capacity can widen Palantir's infrastructure choice for customers that need control over compute, data and models. The release gives no contract value or minimum volume, and both stocks fell Wednesday, so the market withheld a financial premium.

Apple fell 0.28% after unveiling iPhone Duo, iPhone 18 Pro, Apple Watch Series 12 and AirPods 5 during Wednesday's session.

Minor move · iPhone Duo launch and wider hardware event · settled close

Close $315.34, -0.28% from $316.22
Traded from $309.90 to $319.15, a 2.98% low-to-high range
Volume 65.37m shares against a 41.10m average, 159% of normal
Premarket +1.16% at $319.01, a provisional extended-hours print
Closed 8.48% below its 52-week high of $344.57
Volume reached 159% of normal, the second-heaviest volume of the twelve
iPhone Duo starts at $1,999, with pre-orders on 16 October and availability on 23 October
The foldable has a 7.6-inch inner display and uses the A20 Pro, N1 wireless chip and C2 modem
AirPods 5 start at $129; Apple Watch Series 12 starts at $399

Why it mattersDuo opens a premium foldable category and brings a $1,999 starting price, but its 23 October availability delays the demand read. A nearly flat close on elevated volume means the event changed Apple's product map without producing a decisive same-day valuation move.

Tesla closed almost flat, down 0.10%, without a material company announcement dated 9 September in the sources reviewed.

Minor move · no newly dated company catalyst · settled close

Close $367.81, -0.10% from $368.16
Traded from $366.00 to $375.44, a 2.58% low-to-high range
Volume 32.49m shares against a 43.58m average, 75% of normal
Premarket -0.52% at $365.90, a provisional extended-hours print
Closed 26.27% below its 52-week high of $498.83
It moved -0.12% from the open to the close
Wednesday's close remained 2.27% below the 3 September close of $376.36

Why it mattersThe latest identified company-specific facts remain the 3 September Cybercab launch and the NHTSA investigation opened on 4 September. A nearly unchanged close and a 0.52% premarket decline do not establish a new operating verdict.

Intel rose 9.05%, the largest gain of the twelve, after DigiTimes reported that another roughly 10% increase in PC-CPU prices is planned around 5 October.

Major move · reported pricing action, not company guidance · settled close

Close $104.47, +9.05% from $95.80
Traded from $100.35 to $106.09, a 5.72% low-to-high range
Volume 139.49m shares against a 86.19m average, 162% of normal
Premarket -1.79% at $102.60, a provisional extended-hours print
Closed 26.61% below its 52-week high of $142.35
The +9.05% advance was the largest gain of the twelve
It gained 3.61% from its $100.83 open
The reported increase is roughly 10% and is said to begin around 5 October

Why it mattersA higher selling price can lift gross margin if unit volume holds. It can also weaken demand or accelerate substitution, and Intel had not announced the reported change, so Tuesday's price move is evidence of investor reaction rather than confirmation of the policy or its earnings effect.

Nebius gained 7.73% before management's 18:45 ET Goldman Sachs conference appearance; the presentation therefore cannot explain Tuesday's settled advance.

Major move · after-close demand detail · settled close

Close $243.88, +7.73% from $226.39
Traded from $234.32 to $254.74, a 8.71% low-to-high range
Volume 26.60m shares against a 13.77m average, 193% of normal
Premarket -1.18% at $241.00, a provisional extended-hours print
Closed 18.67% below its 52-week high of $299.86
The +7.73% rise was the second-largest gain of the twelve
Volume reached 193% of normal, the heaviest participation of the twelve
It gained 3.85% from the open and traded across an 8.71% low-to-high range
Management described four recent customer wins averaging about $1bn each

Why it mattersThe after-close comments are relevant to Wednesday rather than the Tuesday tape. Management said demand reaches into the first half of 2028, four recent customer wins average about $1bn each, and Blackwell capacity cleared at prices 15-20% above the prior list. Those claims strengthen the demand picture but do not disclose contract-by-contract margins or cash timing.

Tesla rose 3.98% without a material company announcement dated 8 September, recovering part of Friday's 5.92% decline.

Major move · no newly dated company catalyst · settled close

Close $368.16, +3.98% from $354.08
Traded from $355.80 to $370.00, a 3.99% low-to-high range

Premarket -1.01% at $364.45, a provisional extended-hours print
Closed 26.20% below its 52-week high of $498.83
It gained 3.05% from the $357.27 open
Tuesday's close remained 2.18% below Thursday's $376.36 close
The last identified company-specific shock remains the NHTSA investigation disclosed on 4 September

Why it mattersA rebound after a sharp investigation-led sell-off can reflect short covering or a lower risk premium, but it does not resolve the NHTSA Cybercab inquiry. Tesla still closed 2.18% below Thursday's level and is 1.01% lower premarket, so the two-session evidence remains mixed.

Robinhood fell 3.91% even after announcing a multi-year Crypto.com and OG.com agreement for football event contracts and equity stakes in both businesses.

Major move · strategic prediction-markets deal · market rejected

Close $117.34, -3.91% from $122.11
Traded from $117.08 to $125.22, a 6.95% low-to-high range
Volume 25.84m shares against a 22.51m average, 115% of normal
Premarket +1.07% at $118.60, a provisional extended-hours print
Closed 23.74% below its 52-week high of $153.86
Opened at $125.07 and fell 6.18% to the close
Robinhood said it will continue routing contracts to Kalshi, ForecastEX and Rothera as well as OG.com
The company reported more than 30bn event contracts through the end of August this year

Why it mattersThe agreement broadens supply and gives Robinhood equity exposure, but it does not disclose purchase price, ownership percentage, revenue share or expected earnings. The shares fell 6.18% from the open and closed near the session low, so the market did not reward the announcement on Tuesday.

Palantir fell 2.31% without a material filing, contract or company announcement dated 8 September in the sources reviewed.

Notable move · no newly dated company catalyst · settled close

Close $170.30, -2.31% from $174.33
Traded from $170.02 to $175.82, a 3.41% low-to-high range
Volume 24.44m shares against a 29.91m average, 82% of normal
Premarket +0.41% at $170.99, a provisional extended-hours print
Closed 17.94% below its 52-week high of $207.52
It fell 1.62% from the open to the close

Why it mattersThe absence of a dated catalyst makes the rate-and-positioning explanation more credible than a new operating fact. The stock recovered 0.41% premarket, but that provisional move is too small to overturn Tuesday's decline.

Nvidia fell 2.01%; after the close, a Form 4 disclosed director Mark Stevens's sale of 1,022,239 shares completed on 3-4 September.

Notable move · director sale disclosed after close · settled close

Close $225.73, -2.01% from $230.36
Traded from $224.85 to $233.71, a 3.94% low-to-high range
Volume 118.98m shares against a 157.64m average, 75% of normal
Premarket -0.63% at $224.31, a provisional extended-hours print
Closed 4.57% below its 52-week high of $236.54
The disclosed sales totalled 1,022,239 shares at an average of about $230.51
Approximate proceeds were $235.6m; retained ownership was about 28.9m shares
The close was 4.57% below the 52-week high, the smallest gap of the twelve

Why it mattersThe disclosure date is Tuesday, but the transactions happened earlier and therefore cannot explain the entire settled move. At an average price near $230.51, the sales total about $235.6m; the filing also shows Stevens retained roughly 28.9m shares, so the transaction is material but not an exit.

Apple fell 1.17% ahead of today's confirmed 10:00 PT company event; no material operating announcement dated Tuesday was found.

Notable move · launch event ahead, no Tuesday operating update · settled close

Close $316.22, -1.17% from $319.97
Traded from $314.92 to $320.70, a 1.84% low-to-high range
Volume 35.03m shares against a 37.10m average, 94% of normal
Premarket -0.25% at $315.43, a provisional extended-hours print
Closed 8.23% below its 52-week high of $344.57
Apple's official event begins 9 September at 10:00 PT / 13:00 ET / 18:00 London

Why it mattersThe event creates near-term product and guidance risk, but the official notice does not identify the products. Tuesday's decline is therefore a positioning move into a known event rather than a response to confirmed launch details.

Microsoft fell 1.15% as it announced that Codename MDASH has been deployed to Azure Government for preview by selected US government customers and partners.

Notable move · Azure Government security preview · settled close

Close $493.95, -1.15% from $499.70
Traded from $490.15 to $495.19, a 1.03% low-to-high range
Volume 18.68m shares against a 22.27m average, 84% of normal
Premarket +0.14% at $494.62, a provisional extended-hours print
Closed 10.79% below its 52-week high of $553.72
Microsoft says MDASH combines more than 100 agents
The company reported a public CyberGym score of 96.55 and expects a newer MAI model to halve scan cost

Why it mattersThe deployment expands Microsoft's autonomous cybersecurity offer into a regulated customer base. The announcement gives no contract value, adoption count or revenue timetable, and the stock's decline alongside QQQ indicates that the market did not assign an immediate financial uplift.

Marvell rose 0.83% without a material company announcement dated 8 September in the sources reviewed.

Minor move · no newly dated company catalyst · settled close

Close $225.41, +0.83% from $223.55
Traded from $222.53 to $231.89, a 4.21% low-to-high range
Volume 20.29m shares against a 24.98m average, 81% of normal
Premarket -1.25% at $222.60, a provisional extended-hours print
Closed 31.67% below its 52-week high of $329.88
It fell 0.69% from the open despite finishing above the prior close

Why it mattersA small advance without fresh operating data is better treated as sector positioning than a change in Marvell's earnings path. The 1.25% premarket decline has already more than offset Tuesday's percentage gain.

Amazon fell 0.60% as AWS and Qualcomm announced a multi-generation collaboration on custom AI-inference silicon and 1.6-terabit optical connectivity.

Minor move · conditional Qualcomm collaboration · settled close

Close $256.97, -0.60% from $258.51
Traded from $254.75 to $257.99, a 1.27% low-to-high range
Volume 28.79m shares against a 32.07m average, 90% of normal
Premarket -2.14% at $251.46, a provisional extended-hours print
Closed 10.53% below its 52-week high of $287.20
Reuters said the arrangement could cover up to $60bn of chips and products; that is a ceiling, not an order
The warrants were described as worth roughly $4bn at a Qualcomm share price of $161.26
The -2.14% move is the weakest premarket reading of the twelve

Why it mattersThe partnership can diversify AWS silicon and networking supply, but Reuters described the $60bn figure as a maximum under the arrangement rather than committed spending. Qualcomm warrants vest with purchases, so the economics depend on future product uptake.

Meta fell 0.53% on Tuesday, then rose 4.32% premarket after launching Muse, a general-purpose personal AI agent, late in the session.

Minor settled move · Muse launched late Tuesday · premarket reaction

Close $613.48, -0.53% from $616.77
Traded from $609.74 to $624.80, a 2.47% low-to-high range
Volume 18.30m shares against a 17.22m average, 106% of normal
Premarket +4.32% at $640.00, a provisional extended-hours print
Closed 22.42% below its 52-week high of $790.80
The +4.32% rise is the strongest premarket reading of the twelve
Muse is rolling out in the US on iOS, Android and muse.ai, with free core access and paid plans
Meta says Muse can work inside WhatsApp, send email, book travel and use Stripe Link for checkout

Why it mattersMuse gives Meta a direct consumer-agent product with free and paid plans, but no user, price, revenue or cost guidance was disclosed. The premarket rise is the clearest reaction available; it remains provisional and may also include macro and positioning effects.

Alphabet was nearly flat on Tuesday, then fell 1.14% premarket as Google announced a €13bn Finland digital-and-AI infrastructure investment for 2027-2028.

Minor settled move · Finland investment announced Wednesday · premarket

Close $338.36, -0.03% from $338.46
Traded from $333.22 to $339.67, a 1.93% low-to-high range
Volume 22.26m shares against a 23.54m average, 95% of normal
Premarket -1.14% at $334.50, a provisional extended-hours print
Closed 17.19% below its 52-week high of $408.61
Google described the €13bn programme as running across 2027-2028
The plan covers Hamina, Kajaani, Muhos and Vaala and was described by Google as its largest single investment in Europe

Why it mattersThe investment adds capacity and supports long-run AI supply, but it is also a large capital commitment whose returns depend on demand and execution. Because the announcement is dated Wednesday, it cannot explain Tuesday's settled move.

Nebius rose 7.48% on Friday without a filing, contract or company announcement dated 4 September.

Major move · sector and positioning, not company · settled close

Close $226.39, +7.48% from $210.63
Opened -0.21%, then moved +7.71% from the open to the close
Volume 14.89m shares against a 12.80m average, 116% of normal
Premarket +2.48% at $232.00, a provisional extended-hours print
Closed 24.50% below its 52-week high of $299.86
The 7.48% advance was the largest gain of the twelve
It opened 0.21% lower, then gained 7.71% from the open
Reports tying the move to a new Lone Pine position describe a quarterly holding disclosure, not a transaction completed on Friday

Why it mattersNebius sells compute capacity that has to be financed and built before its contracted revenue arrives. Friday's rise ran against higher Treasury yields, so it cannot be explained cleanly by the rate channel. With no newly dated contract, the safer reading is renewed demand for AI-infrastructure exposure rather than a change in Nebius's cash-flow forecast.

Marvell rose 7.05% on Friday with no company release dated 4 September; contemporaneous coverage connected the move to the AI-infrastructure bid after Nvidia's Hugging Face agreement.

Major move · sector read-through, not a new company release · settled close

Close $223.55, +7.05% from $208.83
Opened +1.36%, then moved +5.62% from the open to the close
Volume 21.15m shares against a 24.83m average, 85% of normal
Premarket +0.56% at $224.80, a provisional extended-hours print
Closed 32.23% below its 52-week high of $329.88
The 7.05% advance was the second-largest gain of the twelve
The acquisition read-through was already known: reports appeared on 26–27 August and Nvidia confirmed terms on 3 September
Friday's rise came on 85% of average volume, so participation did not confirm a broad re-rating

Why it mattersMarvell supplies the custom silicon and connectivity that let AI clusters move data. A larger model and deployment ecosystem increases demand for that layer, even when the acquisition belongs to Nvidia. The link is indirect, however, and no Marvell revenue was attached to Friday's move.

Intel rose 4.51% on Friday without a newly dated company announcement, then gained another 4.30% premarket today after DigiTimes reported a planned 10% CPU price increase for early October.

Major move · company report today, settled move lacked a clear catalyst · settled close

Close $95.80, +4.51% from $91.67
Opened +0.85%, then moved +3.62% from the open to the close
Volume 97.43m shares against a 81.93m average, 119% of normal
Premarket +4.30% at $99.92, a provisional extended-hours print
Closed 32.70% below its 52-week high of $142.35
The 4.51% Friday advance was the third-largest gain of the twelve
Premarket +4.30% is the strongest premarket of the twelve
Intel has the widest gap to its 52-week high of the twelve, closing 32.70% below $142.35
Dow Jones said the reported increase responds to supply-chain costs and strong demand; Intel had not commented when the report was published
A separate Intel-ASML production milestone recirculating today is dated 15 July, not 7 September

Why it mattersA 10% list-price increase can lift gross profit quickly if customers accept it, which matters because foundry spending and weak manufacturing utilisation still burden Intel's margin. The trade-off is unit share: higher prices make Qualcomm and MediaTek more competitive in price-sensitive PC and embedded markets. The premarket move is a margin bet based on an unnamed-source report, not confirmed guidance.

Meta rose 1.00% on Friday with no material filing, contract, result or company announcement dated 4 September.

Minor move · sector, not company · settled close

Premarket -1.02% at $610.48, a provisional extended-hours print
Closed 22.01% below its 52-week high of $790.80
The 0.27% opening gap and 0.72% rise from the open show an orderly session rather than a single news repricing
Muse Spark 1.3 was released on 2 September and was already reflected in Thursday's move

Why it mattersMeta's valuation is being set by the expected return on AI capital expenditure. Friday added no new evidence about model adoption, advertising revenue or the 2027 spending plan, so the gain reads as residual sector demand rather than a change in estimated earnings.

Nvidia rose 0.84% on Friday; on 8 September, Nvidia-backed Firmus announced OpenAI as an anchor customer for two Malaysian AI factories using Nvidia's Vera Rubin systems.

Minor move · company ecosystem · settled close

Close $230.36, +0.84% from $228.45

Premarket +0.31% at $231.08, a provisional extended-hours print
Closed 2.61% below its 52-week high of $236.54
Firmus said its contracted customer portfolio now exceeds 900 MW, with five sites under development over the next 24 months
The release did not disclose OpenAI's contract value, the number of Nvidia systems or revenue flowing to Nvidia
Nvidia closed with the smallest gap to its 52-week high of the twelve, 2.61% below $236.54

Why it mattersThe Firmus contract is evidence that demand for Rubin systems is broadening into Southeast Asia, but it is not a disclosed Nvidia order. It supports utilisation of Nvidia's platform and software ecosystem without giving enough information to change a revenue estimate.

An Amazon Air-branded Boeing 767 operated by 21 Air overran a runway in Miami on Sunday 6 September, killing five people on the ground and injuring five others; the NTSB investigation continued Monday.

AP reported that the aircraft travelled about 1,300 feet beyond the paved surface
Amazon said it would cooperate with the investigation; no financial exposure, service disruption or liability estimate was disclosed
The stock had closed 0.15% lower on Friday, before the crash, and is 0.99% lower premarket

Why it mattersThe immediate financial effect cannot be sized because the aircraft was operated by a contractor and the allocation of insurance and liability has not been disclosed. The event matters operationally if the investigation changes Amazon Air procedures or capacity, but a single aircraft does not yet change the earnings power of the retail or AWS businesses.

Alphabet fell 1.17% on Friday with no material company announcement dated 4 September.

Notable move · macro, not company · settled close

Close $338.46, -1.17% from $342.48

Premarket -0.73% at $336.00, a provisional extended-hours print
Closed 17.17% below its 52-week high of $408.61
The shares traded ex-dividend for $0.22 on 4 September, equal to about 0.06% of the prior close, so the dividend explains little of the decline
The ad-tech ruling was dated 2 September and was already covered in the prior edition

Why it mattersAlphabet's advertising cash flow is current, but its valuation still falls when bond yields rise because investors compare those earnings with a higher risk-free return. With no new company fact, the jobs report and the resulting rate-hike repricing are the direct explanation.

Microsoft fell 2.04% on Friday with no newly dated contract, filing or product announcement.

Notable move · macro, with an older service incident · settled close

Volume was 82% of average, the lightest relative participation of the twelve
Microsoft 365 and Outlook issues discussed in weekend coverage began earlier in the week and were not a new Friday event
The Azure reporting change was announced on 2 September and was already reflected in Thursday trading

Why it mattersMicrosoft carries both long-duration AI expectations and a mature subscription base. Higher yields reduce the present value of the AI build-out, while a service incident matters only if it causes persistent churn or credits. No such financial effect was disclosed, leaving rates as the cleaner explanation for Friday.

Robinhood fell 2.09% on Friday after Thursday's 16.57% rise, with no new filing or company announcement dated 4 September.

Notable move · reversal, not a new company event · settled close

Close $122.11, -2.09% from $124.72

The shares opened 3.40% lower and recovered 1.36% from the open
Oura's IPO registration, filed on 3 September, lists Robinhood among the underwriters; the filing predates Friday's session and discloses no Robinhood fee
Premarket -1.93% is the weakest premarket of the twelve

Why it mattersUnderwriting moves Robinhood into another capital-markets revenue line, but one IPO fee is unlikely to change group earnings. Friday reads as profit-taking after an unusually large Thursday move rather than a verdict on the Oura role.

Apple fell 2.51% on Friday ahead of its 9 September event; Apple announced the event on 26 August, so the date itself was not new Friday information.

Notable move · event risk, not a new announcement · settled close

Apple's official invitation confirms 10:00 PT on Wednesday but does not confirm which products will appear
Premarket is -0.45%

Why it mattersApple's next valuation input is the product and price mix presented Wednesday. Friday's decline raises the hurdle for the event but does not reveal whether unit demand, component cost or margins changed. The official material still confirms a time, not a product list.

Palantir fell 4.49% on Friday with no company announcement dated 4 September, reversing part of Thursday's rally on the expanded PwC alliance.

Major move · reversal, not company · settled close

Opened -1.38%, then moved -3.16% from the open to the close
Volume 27.90m shares against a 30.98m average, 90% of normal
Premarket -0.00% at $174.33, a provisional extended-hours print
Closed 15.99% below its 52-week high of $207.52
The stock opened 1.38% lower and then fell a further 3.16% from the open
The PwC announcement is dated 3 September and disclosed no contract value or revenue share
Premarket is effectively flat at -0.00%

Why it mattersPalantir's multiple depends on growth continuing without delivery costs rising at the same pace. The PwC alliance supports that thesis, but the lack of a disclosed customer or contract value leaves investors with no near-term revenue to model. Friday removed part of the announcement premium as rates moved against long-duration software.

Tesla fell 5.92% on Friday after the NHTSA opened an investigation into whether steering-wheel-free Cybercabs deployed in Austin comply with federal safety rules.

AP reported that the vehicles lack steering wheels, pedals and mirrors; Tesla began offering rides after Thursday evening's invitation-only launch
Premarket is +0.26%

Why it mattersThe Cybercab value case requires both low hardware cost and permission to carry paying passengers. Removing manual controls lowers the vehicle cost while making federal compliance harder. The investigation therefore goes directly to the probability and timing of robotaxi revenue, rather than to a cosmetic feature of the launch.

Robinhood rose 16.57% with no filing, contract or company announcement dated 3 September, after two brokerages published work on its prediction-markets business.

Volume 51.38m shares against a 24.80m average, 207% of normal and the heaviest relative participation of the twelve

Deutsche Bank's Brian Bedell argued contracts on companies' own KPIs could become the largest category in the business, and put US company-KPI contract volume above $1 trillion by 2028
Piper Sandler's Patrick Moley kept a $145 target and pointed to the NFL and NCAA football seasons after strong engagement around the 2026 World Cup
The company figure underneath is from results dated 29 July: event-contract revenue $156m in the second quarter, more than 10x a year earlier, on a record 13.6bn contracts, and ahead of crypto revenue for the first time
Total second-quarter net revenue was $1.31bn, up 32%, so event contracts were about 12% of the company
Closed 18.94% below its 52-week high of $153.86

Why it mattersRobinhood has been priced as a geared bet on retail trading volume, and investors pay little per dollar of earnings for revenue that swings with the market. Prediction markets are a different kind of revenue: exchange economics, driven by sporting and political calendars rather than by share prices, so it does not fall when equity volumes fall. Revenue that is uncorrelated and repeatable carries a much higher multiple than revenue that is cyclical. Thursday was investors starting to underwrite a 2028 revenue line that does not exist yet, which is why the move dwarfs anything in the current quarter.

PwC US and Palantir announced on 3 September that they are expanding their strategic alliance, initially across enterprise AI, mergers and acquisitions, and ERP modernisation.

Volume 38.01m shares against a 32.29m average, 118% of normal
Opened 1.71% higher and then rose 5.91% from there, so the session, not the gap, carried it
The centrepiece is an AI-native deals platform PwC and Palantir say executes transactions up to 50% faster and cuts one-time costs by up to 45%. No contract value or revenue-share was disclosed
This recovers Wednesday's fall. Palantir closed at $179.92 on Tuesday and $169.46 on Wednesday, a 5.81% drop, so Thursday's close is still 1.45% above where it stood on Tuesday
Closed 12.04% below its 52-week high of $207.52

Why it mattersPalantir's constraint has never been demand, it is the cost of delivery: every deployment needs its own engineers, so revenue growth has always dragged headcount and services cost along with it. A Big Four firm doing the implementation work changes the shape of the business, not the size of one contract. It converts Palantir toward selling a platform that someone else installs, which is the difference between a consultancy that scales linearly and software that does not. That is a gross-margin argument and a sales-reach argument at once, and it is the thing that would justify what investors already pay per dollar of Palantir's earnings.

Tesla unveiled the production Cybercab at an invitation-only event in Austin on the evening of 3 September, after the market had closed.

Major move · the move came BEFORE the event · settled close

Close $376.36, up 5.42% from $357.01, the third-largest gain of the twelve
Volume 62.84m shares against a 41.46m average, 152% of normal
The entire 5.42% was made before the event: a 2.49% gap at the open and 2.86% more during the session, all of it in regular trading hours
Cybercab is a two-seat robotaxi with no steering wheel, no pedals and no mirrors, at a $25,000 starting price and a stated 418 mile range. Production began at Gigafactory Texas in the first half of 2026
The NHTSA said it is in contact with Tesla and is evaluating the Texas rollout, because federal safety standards normally require controls the Cybercab does not have
Tesla did not livestream the event publicly, which drew complaints from retail holders
Premarket -2.02%, the weakest premarket of the twelve
Closed 24.55% below its 52-week high of $498.83

Why it mattersTesla's share price stopped being a car multiple some time ago. What investors are paying for is the option that a fleet of driverless vehicles earns fare revenue at software margins with no driver to pay. The two numbers that decide whether that option is worth anything are how many cars are actually carrying paying passengers, and whether a regulator lets them. A vehicle with no steering wheel is the cheapest possible robotaxi to build and the hardest one to get approved, so the NHTSA's evaluation is the live variable, not the unveiling.

Nebius rose 3.20% with no filing, contract or announcement dated 3 September beyond a routine director Form 4 disclosing 5,885 shares after an RSU grant.

Major move · sector, not company · settled close

Close $210.63, up 3.20% from $204.09
Volume 10.64m shares against a 13.33m average, 80% of normal, so this was a small crowd

Closed 29.76% below its 52-week high of $299.86
Its $5.75bn convertible raise, widely recirculated in coverage on 4 September, closed on 24 August and is not new

Why it mattersThis is the rate trade in its purest form. Nebius sells AI compute it has not built yet, funded with convertible debt, against contracts that pay out over years. Almost all of its value sits in cash flows a long way out, so what moves it is not demand for GPUs but the rate at which 2029 cash gets valued today. Waller shaving the odds of a rate rise is worth far more to Nebius than to a company earning its money today, and Thursday's ranking sorted almost exactly that way.

Volume 19.69m shares against a 16.47m average, 120% of normal, the third-heaviest relative participation of the twelve

Benchmark scores put it alongside leading models from OpenAI and Anthropic, on the company's own account. Meta AI chief Alexandr Wang framed it as groundwork for personal AI assistants
Closed 22.78% below its 52-week high of $790.80, further below its high than any of the twelve except Marvell, Intel, Nebius and Tesla
Its $17.1bn multistate teen-safety settlement, still circulating in coverage, was approved on 26 August and is not new

Why it mattersMeta has spent two years asking investors to fund capital expenditure on AI without showing a model that competes at the frontier, and the share price carries the doubt: it sits further below its high than any of the twelve except Tesla, Nebius, Intel and Marvell. A credible frontier model does not add revenue next quarter. What it changes is whether the capex is an asset or a write-off, and therefore whether investors keep applying a discount to Meta's earnings for money they think is being wasted. That discount, not advertising growth, is the swing factor in the multiple.

Microsoft said on Wednesday 2 September that it will report Azure revenue in dollars every quarter and will cut its operating segments from three to two.

Closed 7.87% below its 52-week high of $553.72, the third-smallest gap to its high of the twelve
The $678bn backlog and Azure passing $100bn for the year, both recirculating this week, came with results on 29 July and are not new

Why it mattersFor more than a decade Microsoft gave a growth percentage for Azure and no dollars, so nobody outside could tell how big it actually was or what it earned. That opacity has a price: investors apply a discount when they cannot separate the fast-growing business from the slow one bundled with it. Putting a dollar figure on Azure lets the market value it against AWS and Google Cloud directly, at cloud multiples rather than at a blended Microsoft multiple. Nothing about the business changed on Wednesday. What changed is how much of it investors can see, and visibility is worth a re-rating on its own.

Nvidia confirmed on 3 September that it will acquire Hugging Face, the open-model hosting platform, for about $12.9bn. The definitive agreement is dated 2 September.

Notable move · company · settled close

Close $228.45, up 1.80% from $224.41, on 86% of average volume
Deal terms: about $11.9bn payable to Hugging Face stockholders, subject to adjustment, plus an equity retention pool of up to about $1.0bn for employees joining Nvidia
Against Hugging Face's $4.5bn valuation at its $235m round in 2023, that is roughly 2.9x in three years
Hugging Face hosts about 3m models, 1m applications and 500,000 datasets, used by more than 18m developers
Expected to close in the first half of 2027, subject to regulatory approval. Jensen Huang said Hugging Face stays open and that Nvidia compute will not be required to build or deploy there
Closed 3.42% below its 52-week high of $236.54, the smallest gap to its high of the twelve

Why it mattersNvidia's risk has never been this year's orders, it is that its customers design their way off its chips. Hugging Face is where open models are published and pulled, so whoever runs it sits at the point where a developer picks the hardware their model will run on by default. Buying the distribution layer is a defence of pricing power, not an addition to revenue: $12.9bn is under a fortnight of Nvidia's sales. The commitment to stay hardware-neutral is the price of not driving developers away, and it is also what makes regulatory approval plausible.

Intel rose 1.80% with no filing, contract or announcement dated 3 September, on the same semiconductor and rate-relief bid that lifted the group.

Notable move · sector, not company · settled close

Close $91.67, up 1.80% from $90.05, on 98% of average volume
Opened 0.78% lower and rose 2.60% from there, so the whole move was made after the open
Now 3.55% below the $95 price of its $20bn equity offering, which priced on 10 August, against 6.35% below it on Tuesday
Closed 35.60% below its 52-week high of $142.35, the second-widest gap to its high of the twelve

Why it mattersIntel is the one name here where the discount rate barely matters, because almost nothing in the price is a bet on profits far in the future. What sets the price is the August equity offering: buyers at $95 are still underwater, and that unsold stock hangs over the shares until it clears. Every dollar closer to $95 shrinks that overhang, which is why Intel trades on its distance from the offering price rather than on the macro.

Judge Leonie Brinkema ruled on 2 September that Google need not sell its AdX ad exchange, imposing behavioural remedies instead. Google shipped Gemini 3.8 Flash the same day.

Notable move · company, dated Wednesday · settled close

Close $342.48, up 1.59% from $337.12, on 87% of average volume
The court rejected divestiture of AdX, rejected open-sourcing the DFP final auction logic, and rejected the contingent divestiture of DFP Remainder
Remedies instead require interoperability, including opening real-time bidding on AdX to rival ad servers. Both sides must file a jointly proposed final judgment within 30 days, and the full opinion stays sealed for 14 days for redaction requests
Gemini 3.8 Flash is the third Flash release in six weeks, priced unchanged at $0.75 per million input tokens and $3.75 per million output tokens. Both prices double on 1 January 2027
A security variant, Gemini 3.8 Flash Cyber, is limited to Google's new Fairwind Program for government and critical-infrastructure users
Closed 16.18% below its 52-week high of $408.61

Why it mattersAd tech is roughly a tenth of Alphabet's revenue, so a forced sale of AdX would have cost less in earnings than in precedent. What the market has been discounting is the tail risk that a court breaks the company up, and this is the second time in about a year that a judge has declined to. Behavioural remedies leave the business intact and merely constrain how the auction runs. Removing a structural risk does not raise next year's profits by a cent; it raises what investors will pay for those profits, because the range of bad outcomes just narrowed.

Amazon rose 1.54% with no filing or announcement dated 3 September, while AWS took a partial outage and reported disruption at a Bahrain facility.

Notable move · sector, not company · settled close

Close $258.90, up 1.54% from $254.98, on 83% of average volume, the third-lightest participation of the twelve
Opened 0.53% higher and added 1.01% during the session
Down Detector user reports pointed to AWS problems in the US during Thursday's session, coinciding with outages at several large AI services. Separately, Iranian strikes were reported to have caused temporary disruption at an AWS facility in Bahrain
Neither event drew an Amazon filing or a service-credit disclosure, and neither is sized
Closed 9.85% below its 52-week high of $287.20, the smallest gap to its high of the twelve after Nvidia, Apple and Microsoft

Why it mattersThe interesting thing about Thursday is what the market ignored. An AWS outage and a physical strike on a data-centre region are precisely the risks that should trouble a business whose customers pay for availability, and the stock rose anyway. That tells you investors treat regional outages as noise against a cloud business growing revenue at 37%, and that Amazon is currently being traded as a rates-and-capex story rather than an operations one. Microsoft's Azure disclosure matters here too: once Azure is reported in dollars, AWS growth gets compared line against line every quarter.

Marvell rose 1.14% with nothing dated 3 September, after opening lower on Broadcom's results and recovering through the session.

Broadcom fell about 6% on Thursday on soft guidance, despite AI revenue up 221%. Marvell finished higher on the same day
Closed 36.70% below its 52-week high of $329.88, the widest gap to its high of the twelve
Its second-quarter results, record revenue of $2.739bn up 37%, and the raised fiscal 2027 and 2028 outlook, are dated 27 August and are not new
Premarket +2.45%, the strongest premarket of the twelve

Why it mattersBroadcom and Marvell both sell custom AI silicon, so a weak guide from the larger one normally drags the smaller one with it. Thursday broke that link, and the reason is what each guide contains. Broadcom's disappointment was about the pace of its existing programmes; Marvell's own raised outlook, a week old, points at fiscal 2028 and 2029 revenue that has not been booked yet. When the rate on future money falls, the company whose revenue is further out benefits more, and that was enough to offset a bad read-across. Same industry, opposite treatment, and the difference is entirely timing.

Apple rose 1.00% with no filing or announcement dated 3 September, the smallest gain of the twelve.

A £2bn UK class action over App Tracking Transparency was reported on 3 September. The claim is not new litigation filed that day and Apple has not filed on it
Omdia reported that Apple has dropped plans for two MacBook models. Apple has not confirmed this

Why it mattersApple is the shortest-duration story on this list: its cash arrives now, from products already selling, so a change in the discount rate barely touches it. That is why Thursday's rate news did so little for Apple, and why the same insulation helped it when yields were climbing on Tuesday. What actually moves Apple is the product cycle, and the next reading on that arrives in five days.

John Ternus became chief executive on 1 September, and Apple filed an amended Form 8-K that day setting out what he and Tim Cook will be paid.

Opened at $316.98, 0.04% above Monday's close, and rose 2.57% from there. Only Apple and Robinhood opened above Monday's close, and only Apple also finished above it
Ternus: salary raised to $3m; fiscal 2027 annual equity award targeted at $55m; a prorated fiscal 2026 award targeted at $2.5m. Fiscal 2027 target pay about $58m
75% of the fiscal 2027 equity is performance RSUs vesting on Apple's total shareholder return relative to the rest of the S&P 500. The other 25% vests on time, 12.5% semiannually over four years
Cook, now executive chairman: salary $2m from 26 September, fiscal 2027 equity targeted at $45m, split evenly between performance and time-based RSUs. Target pay about $47m
Closed 5.64% below its 52-week high of $344.57, the smallest gap to its high of the twelve

Why it mattersA chief executive succession is a risk premium question, not an earnings question. For years the market has held back part of what it would otherwise pay per dollar of Apple's earnings, against the chance the handover goes badly. Tuesday removed the uncertainty about timing and about whether Cook walks away; the filing removed the uncertainty about incentives. Tying three-quarters of the new CEO's equity to beating the S&P 500 on total return, rather than to revenue or unit shipments, points him at the share price directly. Paying Cook $45m of equity on the same measure is the board buying continuity rather than accepting a clean break. Less transition risk, a smaller discount, a higher multiple on unchanged earnings.

Palantir fell the most of the twelve, with no filing, contract or announcement dated 1 September.

Major move · sector, not company · settled close

Close $179.92, down 3.47%, the largest fall of the twelve
Volume 24.39m against a 30.80m average, 79% of normal: a heavy fall on light participation
Gapped down 1.95% at the open and fell a further 1.55% through the session, one of only four of the twelve to close below its open
Closed 13.30% below its 52-week high of $207.52

Why it mattersPalantir is the clearest duration bet on this list. Almost none of what investors pay for sits in current earnings, so the price is a long stream of future profit discounted back, and moving that rate reprices it hard. The light volume matters: this was not investors selling a Palantir view, it was the absence of buyers on a bad macro day. Nothing about the government backlog changed on Tuesday.

Nebius fell 3.29% on the same rate move, with no company announcement dated 1 September.

Major move · sector, not company · settled close

Opened 3.48% below Monday's close, further below it than any of the other eleven, and recovered almost none of that
Closed 33.46% below its 52-week high of $299.86

Why it mattersNebius builds data centres with borrowed money and rents them out later. That makes it the cleanest casualty of a bond selloff here: the cost of the debt funding the build and the rate applied to future rental income both move against it at once. Oracle fell about 4% on Tuesday for the same reason, and it is a better read-across for Nebius than any chip name.

Tesla gave back the bulk of Monday's 5.51% rise, with no company filing dated 1 September.

Cybercab units listed in the Texas Motor Carrier Credentialing System rose from 7 to 45 by 31 August

Why it mattersMonday's gain was anticipation of Thursday's Cybercab event, not a disclosure, and anticipation is the first thing sold when the macro turns. The drop in volume from 162% to 94% of average confirms it: Monday's buyers did not come back to defend the price. Tesla's valuation above a carmaker's rests on autonomy earning money, and a fleet registered at 45 vehicles is a demonstration, not a business.

Amazon fell a second day after Monday's FTC and 22-state complaint over its advertising auctions.

Notable move · second day of the FTC suit · settled close

Close $254.92, down 1.87%, after Monday's -2.50%: down 4.32% across the two sessions
Volume 31.42m against a 33.80m average, 93% of normal, down from 134% on Monday
The whole fall was the opening gap of 1.90%. Amazon closed 0.04% above its open, so the regular session added nothing
The complaint alleges more than $20bn taken from over 1.2m advertisers. Amazon's advertising revenue was $19.8bn in the June quarter

Why it mattersThe intraday flatline is the useful part. Nobody pressed the case further and nobody bought the dip. That is what a legal overhang looks like after day one: the news is priced, the length of the uncertainty is not, and trading stops until something new arrives. Advertising is close to pure margin for Amazon, so any settlement constraining how auction prices are set lands on operating profit rather than on sales.

The $3.5bn MediaTek convertible purchase was confirmed 31 August, about 90% of a $3.9bn issue Alphabet also joined. It closes 8 September

Why it mattersNvidia held up better than the AI names it supplies. Its earnings are collected now, so a higher rate on future money takes less out of its value than out of Palantir or Nebius. The MediaTek bond is priced and a day old, but the structure stands: Nvidia increasingly funds the buyers of its own chips, which makes backlog a weaker independent signal of demand.

Why it mattersAlphabet tracked the tape, which after Monday's 2.09% fall on no news is itself informative. Two sessions of index-following price action say the capex argument that dominated last week has stopped setting the price day to day.

Microsoft fell 1.24% with no announcement dated 1 September. Two routine Form 4 filings covered scheduled equity vesting.

Satya Nadella's Form 4 reported 178,622 shares vesting with a portion withheld for tax; the chief commercial officer vested 29,724 with 18,080 withheld

Why it mattersScheduled vesting is an accounting event, not a signal: shares withheld for tax are surrendered to the company rather than sold, so nothing reaches the tape. The two-day slide is the same rate story, softened because Microsoft collects most of its earnings now.

Robinhood opened higher and then fell all day, with no company filing of its own dated 1 September.

The Form 144 circulating for 4.1m RVI shares is Robinhood filing as broker for a holder of another company's stock, not a sale of its own

Why it mattersRobinhood's earnings track trading volumes, which rise with volatility, so a fearful tape is not straightforwardly bad for it. A sustained rise in long yields is, because it compresses the multiple paid for a business whose growth depends on retail risk appetite. Opening higher and then being sold all day says which of the two the market was weighting.

The $17.1bn multistate child-safety settlement was announced 26 August; the Instagram Shopping dismissal came 31 August. Neither is news from the past 24 hours

Why it mattersMeta rose because it had already been sold. It sits 26.84% below its high, having taken its legal and AI-spending hits over the past fortnight. On a day the market punished stocks priced for distant profits, a stock already repriced downward has less to give back, and buyers who wanted tech exposure without duration risk had somewhere to go. That is a rotation into cheapness, not a change in the business.

The Google custom-chip agreement worth up to $120bn through fiscal 2033, and guidance that it contributes materially only from fiscal 2029, both date from results on 27 August

Why it mattersThe Google deal is enormous and the payoff is three years out, which is exactly the asset shape a rising discount rate punishes hardest. That is why Marvell is the weakest premarket of the twelve this morning without any new company information. Fiscal 2027 revenue guidance of about $12bn and fiscal 2028 of about $18bn are already on the table. Nothing changed overnight except the price of money.

Reports that SK Hynix is evaluating Intel Foundry for HBM4E base dies are unconfirmed by either company

Why it mattersA rate move barely touches Intel, because almost nothing in its price is a bet on profits far in the future, and the intraday recovery shows it. What still sets the price is the $95 offering: buyers from three weeks ago are underwater, and that supply overhangs the stock until it clears.

The Federal Trade Commission and 22 state attorneys general sued Amazon on Monday, alleging it secretly inflated the prices advertisers paid in its own ad auctions.

Notable move · company · the fall preceded the news

Close $259.77, down 2.50%, the largest fall of the twelve
Volume 45.42m shares against a 33.91m average, 134% of normal and the third-heaviest volume of the twelve
The complaint alleges more than $20bn taken from over 1.2m advertisers, and was filed in the US District Court for the Western District of Washington
Three products are named: Sponsored Products, Sponsored Brands and Sponsored Display. The FTC says Amazon began overriding its auction prices in 2018 and added an undisclosed floor it called a soft reserve price in 2019
Regulators say pay-per-click prices rose by as much as 50% during major shopping events. Reports differ on the period, describing it as five years or seven
Amazon's advertising revenue was $19.8bn in the June quarter, up 26% on a year earlier, on about $180bn of group revenue. Some reports put that growth at 24%
Amazon called the suit misguided and said it strongly disagrees
Intraday: Amazon traded near $261 until the 14:00 ET half-hour, then fell to $257.14 on 5.85m shares, roughly six times the volume of the preceding bar

Why it mattersAdvertising is where Amazon's margin comes from, not where its revenue comes from. Retail is a low-margin business and ads are close to pure profit, which is why investors will pay more per dollar of Amazon's earnings than the retail operation alone would justify. The suit does not attack the size of that business, it attacks the mechanism that sets the price of a single ad. If auctions have to run transparently, the take per ad falls, and that lands on operating margin directly rather than showing up as lost sales. The second effect is slower and larger. A regulator now has discovery rights over how Amazon prices its highest-margin product, and what surfaces in that process tends to outlive the case itself.

Tesla rose 5.51% on Monday with no filing, contract or company announcement dated 31 August. The move tracked anticipation of an invitation-only Cybercab event in Austin on 3 September.

Major move · no company event

Close $367.95, up 5.51%, the largest gain of the twelve
Volume 61.16m shares against a 37.66m average, 162% of normal and the heaviest volume of the twelve
Tesla trades 26.24% below its 52-week high of $498.83
The dated items in the past 24 hours were an Autopilot crash report and remarks about SpaceX building gas turbine parts in-house. Neither is a Tesla financial disclosure
Premarket -1.07%, returning about a fifth of Monday's gain

Why it mattersThis is a sentiment move and should be read as one. Nothing changed on Monday in what Tesla sells, at what price, or at what cost. What changed is how many investors want to hold the shares into a scheduled demonstration. That distinction is the whole point, because a price that rises on positioning falls back on positioning: it has no earnings figure underneath it to defend the level. The Cybercab matters to Tesla's valuation because the robotaxi case is what justifies paying more for Tesla than for a carmaker. But a case is only worth something once it comes with a production date and a cost per vehicle, and Monday supplied neither.

Alphabet fell 2.09% on heavy volume with no filing, contract or company announcement dated 31 August.

Notable move · no company event · sector

Close $339.35, down 2.09%
Volume 33.32m shares against a 22.79m average, 146% of normal and the second-heaviest volume of the twelve
Alphabet is guided to capital spending of roughly $175bn to $185bn in 2026
The dated item was press reporting that meaningful YouTube creator revenue from newer AI features is not expected in force until 2029. That is coverage, not a company statement
Alphabet's £260m UK Play Store settlement, which some outlets ran on Monday, was agreed 27 August and is not news

Why it mattersHeavy volume with no company event is the signature of a sector decision rather than a company one, and the sector here is AI capital spending. Alphabet is the purest case on this list: it is spending at an annual rate close to its own operating profit, and the return arrives on someone else's schedule. When long yields rise, as they did on Monday, the market reprices exactly that gap between spending now and earning later. What moves is not the growth rate but how many years of it investors are willing to underwrite, which is the same thing as what they pay per dollar of earnings.

Anthropic signed a six-year, $35bn cloud computing deal with Lambda, a provider Nvidia backs, reported on Monday by Bloomberg, Reuters and the Wall Street Journal.

Notable move · company · a customer Nvidia helped fund

Close $220.78, up 1.48%, on 86% of average volume
The Anthropic and Lambda agreement is $35bn over six years
Capacity sits in a Hut 8 data centre in Nueces County, Texas. Nvidia contracted with Hut 8 for that capacity several weeks earlier
Anthropic separately committed $45bn over six years to Nscale, also Nvidia-backed, earlier in August
Nvidia trades 6.66% below its 52-week high, the narrowest gap to its 52-week high of the twelve
Neither Nvidia nor Anthropic is a direct counterparty to the other in this agreement. It was reported by news organisations, not announced by Nvidia

Why it mattersThe figure people should watch is not the $35bn, it is who is standing behind the buyer. Nvidia's growth case rests on demand it does not have to finance. Each deal where an Nvidia-backed provider signs an Nvidia-supplied customer converts an Nvidia investment into Nvidia revenue, which is real cash but a weaker signal about the rest of the market. The practical consequence is to the multiple, not the earnings: investors discount revenue whose collectability depends on the seller's own balance sheet. That is why several outlets called the structure circular, and why a good headline number produced only a 1.48% rise on below-average volume.

Marvell fell a further 2.29% with no filing or announcement dated 31 August, extending Friday's 10.28% fall after results.

Notable move · no new event · Friday continuing

Close $211.66, down 2.29%, on 80% of average volume
Marvell sits 35.84% below its 52-week high of $329.88, the second-widest gap to its 52-week high of the twelve
Premarket -2.67%, the weakest premarket print of the twelve
The dated coverage repeated Thursday's raise, to about $18bn of fiscal 2028 revenue from $16.5bn, and the timing problem: the larger Google contribution arrives in fiscal 2029

Why it mattersTwo sessions of falling on no new information is how a stock finishes repricing an expectation rather than a business. Friday established that the raise was smaller than what the price already assumed. Monday and this morning are the position adjustment that follows, on below-average volume, which is consistent with sellers working out rather than new sellers arriving. Nothing here changes the fiscal 2028 forecast. It changes who owns the shares at what cost.

A South Korean report on Monday said SK Hynix was weighing Intel Foundry for the base dies in its next high-bandwidth memory. SK Hynix denied it the same day.

Minor move · a report and a denial in one session

Close $89.51, up 0.04%, on 71% of average volume
The Herald Economy report named HBM4E base dies. SK Hynix said it is not considering Intel Foundry for that work and that parts of the reporting contradict the facts
No agreement was announced by either company
Intel trades 37.12% below its 52-week high of $142.35, the widest gap to its 52-week high of the twelve
Premarket -2.36%, the second-weakest premarket print of the twelve

Why it mattersIntel's foundry case rests entirely on named external customers, because the fabs are already built and the losses are already being taken. A committed customer converts fixed cost into a utilisation rate, which is the single variable that decides whether the foundry ever earns its cost of capital. That is why a rumour like this moves the stock at all. A denial the same day returns the value to zero, and a flat close on light volume says the market priced the round trip correctly.

Monday was Tim Cook's last day as chief executive. John Ternus takes over today, 1 September, with Cook becoming executive chairman.

Minor move · a scheduled handover, known since April

Close $316.85, down 0.89%, on 102% of average volume
The succession was disclosed in April 2026 and reconfirmed 26 August. Today is the effective date, not the announcement
Ternus is 50, joined Apple in 2001 and has led hardware engineering since 2021. The board approved the transition unanimously
Cook's remit as executive chairman is reported to centre on relationships with the US administration and the Chinese government
Separately, Apple accused OpenAI of destroying evidence in its trade-secrets suit, in a filing reported early Tuesday. No damages figure attaches to that motion

Why it mattersA handover disclosed four months ahead carries almost no information on the day it happens, which is the point of announcing it that way. What it does change is where the risk now sits. Apple's China exposure and its tariff position have been managed personally by Cook, and keeping him as executive chairman explicitly for those relationships tells you the board thinks that work does not transfer. The valuation consequence is small and one-directional: the succession risk investors had been discounting since April is now resolved, and nothing new was added.

Robinhood rose 0.53% on Monday and is up 2.61% premarket. Robinhood has the strongest premarket print of the twelve. It is the only one of the twelve above water before the open.

Minor move · premarket unexplained

Close $104.81, up 0.53%, on 73% of average volume
Premarket +2.61%, stamped 06:35 ET
The only dated company item in the past 24 hours is a Form 144 covering 4.1m shares of Robinhood Ventures Fund I, reported early Tuesday. sec.gov is blocked from this environment, so it could not be read directly
Robinhood trades 31.88% below its 52-week high of $153.86
Friday's 5.01% fall on the Ninth Circuit prediction-markets ruling has not been recovered

Why it mattersThis is flagged because the move has no explanation this brief can stand behind. A Form 144 is notice of an intended sale, which is mildly negative if anything, and it does not account for a stock rising while eleven others fall. Robinhood is the highest-beta name on this list and its revenue tracks retail risk appetite directly, so a risk-off morning normally takes it down hard rather than up. Going up while oil spikes and yields rise is the opposite of what its business model implies. Until something dated explains it, treat it as thin premarket noise rather than information.

A US magistrate judge in San Jose dismissed an antitrust claim over Instagram Shopping on Monday, brought by the London startup Ollywan.

Minor move · a dismissal with no figure attached

Close $572.34, down 0.98%, on 78% of average volume
Judge Virginia DeMarchi held the claims were filed too late and did not plausibly show harm to competition, and that antitrust law does not stop Meta enforcing its trademark
The dismissal comes with leave to amend, so the case is not finished
No damages figure was attached to the claim in the coverage
Meta trades 27.63% below its 52-week high of $790.80

Why it mattersA dismissal with leave to amend removes a small tail risk and creates no value, which is why the shares did not move on it. It matters only as a marker in a longer pattern: Meta has now cleared the FTC structural case and this one, and each win reduces the probability investors assign to a forced divestiture. That probability is a discount applied to the whole company, so it is worth more than the size of any individual claim. On Monday it was worth nothing, because the claim was small and the ruling is provisional.
