AI credit stress is the day's driver
The biggest single story across the list is credit, not earnings. Oracle is down 8.8%, and three separate full reads tie it to the same thing: its five-year credit default swap spread widened 26 basis points to a record 288 bps, up from 260 a week earlier. GuruFocus frames this against CoreWeave, whose CDS has blown out past 1,000 bps, an implied 63% chance of default within five years, with its 2032 bonds trading near 78 cents on the dollar at a yield above 16%. The Walter Bloomberg post adds that default insurance costs have also risen for Nvidia, Amazon, Alphabet and Meta, with the core question being whether AI companies can earn enough to service growing debt. A second GuruFocus piece links the move to the FTC issuing subpoenas to Anthropic and OpenAI over AI safety and privacy, and notes Oracle's P/S at 5.34 near a three-year low, debt-to-equity of 2.53, an Altman Z-Score of 1.56, and insider activity over twelve months of $3.5 million bought against $113.2 million sold. Separately, Saxo's note says investors are splitting the AI trade, favouring profitable chipmakers like TSMC, Samsung and ASML over debt-heavy infrastructure names including CoreWeave, Nebius and Oracle, citing CoreWeave's 15% drop Wednesday and a 14% fall in BlackRock's semiconductor ETF over eight sessions.
Nebius caught in the same squeeze
Nebius is down 10.1%, and the Investing.com piece lays out several overlapping causes rather than one. Wednesday's hotter-than-expected September CPI pushed short-term yields up and raised rate-hike expectations, hitting capital-intensive AI infrastructure hardest. CoreWeave's bond yield spike to 15% drew a widely circulated negative comment from Elon Musk, prompting a reassessment of financing risk across the neocloud space. Gartner published a report warning that more than $3.5 trillion of AI infrastructure spending could face impairment by end-2030, singling out neoclouds for their lack of diversified revenue. On top of that, the COO sold 500,000 shares in early October, CRO Marc Boroditsky sold 7,000 on October 12 under a 10b5-1 plan, and Michael Burry is reported to have shifted from a direct short to leveraged puts on the name.
Credo down on no bad news of its own
Credo is down 9.6%, which Mizuho treats as a pullback rather than a problem. The firm reiterated Outperform with a $245 target after meeting CEO Bill Brennan and CFO Dan Fleming at OCP. Credo announced a 1.6T Active Light Cable using µVCSEL at 50m reach, roughly 200 fibers, 30% less power and ten times lighter than AEC, targeting volume deployment in 2027. The µEmitter roadmap includes a 6.4T optical backplane NPO that could ramp in 2027 at 60% lower power than copper, and the supply chain now includes three end users, two leading GPU OEMs and one hyperscaler. Mizuho sees ZFO and NPO work with DustPhotonics and SPCX driving more than $600 million of optical revenue in fiscal 2027, against 67% gross margin and 165% revenue growth. The article also notes Stifel kept a Buy while cutting its target from $350 to $310 on valuation, and that Mizuho had earlier cut from $290 to $245.
Rocket Lab slips Neutron to 2027
Rocket Lab is down 7.8% after disclosing in an 8-K filed October 14 that the first Neutron launch moves into 2027 from a fourth-quarter 2026 target. Engineers found voids, small air pockets, in the carbon-composite forward dome of the first-stage propellant tank, requiring a redesign and process changes. CFO Adam Spice had previously said a successful Neutron test flight was the trigger for turning adjusted EBITDA positive the following quarter, and he sold roughly $9.9 million of stock under a pre-arranged plan in early October. Cantor Fitzgerald kept Overweight and a $122 target, with analyst Andres Sheppard now modelling first launch in Q2 2027 and first revenue-generating launch in Q4 2027, calling the delay disappointing but not material long term. TD Cowen had already trimmed to $90 from $120 earlier this month. The stock is more than 60% below its $151 52-week high on a six-day losing streak.
Surf Air signs its fifth OperatorOS deal
Surf Air Mobility is down 6.3% despite announcing a definitive agreement with Flying Zebra, a four-aircraft operator, for its OperatorOS flight operations software, built on Palantir. It is the fifth commercial OperatorOS contract and goes toward the stated goal of five operators live by end-2026, with Surf Air earning a percentage of revenue on trips run through the platform. The FAA recently approved the software as an authorised system of record for electronic signatures and recordkeeping. The article gives no reason for the share price move.
TSMC: record quarter, stock still lower
TSMC is down 3.4% on a heavy run of headline-only items. Per those headlines, Q3 revenue rose 50.9% to NT$1.49 trillion, net income 68.7% to NT$763.1 billion, EPS NT$29.43, gross margin 66.4% and operating margin 58.7%. Advanced nodes at 7nm and below were 79% of wafer revenue, with 2nm at 8% from 3% the prior quarter, and HPC at 68% of revenue versus 57% a year ago while smartphones fell to 21%. The CFO said 2026–2028 capex will be significantly higher than the past three years, and the CEO said he sees no sign of an AI demand slowdown and no intention to leave business on the table. Several headlines note the stock fell anyway, and one mentions a Texas fab under consideration.
Rest of the semis and the smaller names
The chip complex moved with the same rate-driven selloff: Micron down 4.1%, SanDisk down 5.3%, Broadcom down 3.1%, all headline-only. Micron headlines cite the sector sell-off on rising borrowing costs and AI spending, Chinese competition in memory, and a bonus dispute with a strike threat in Taiwan that the president has urged the company to resolve. One headline reports Anthropic's quarterly revenue rose 45% to $16.8 billion, a sharp slowdown from triple-digit growth, feeding the AI selloff, with another headline saying Anthropic is profitable again. Elsewhere, Citizens cut its Upstart target to $18 on bank charter concerns, with UPST down 4.6%. Goldgroup Mining invested C$101 million in Luca Mining, with GORO down 4.5%. KeyBanc downgraded Cirrus Logic on Apple concerns, and Apple itself closed above a $5 trillion market cap and is up 0.5%, against a headline saying global smartphone shipments fell 22% in Q3 on rising storage costs. Jefferies assumed Netflix with a Buy and an $85 target, BofA resumed PayPal at Underperform, and TD Cowen raised Accenture to $201 on its AI growth outlook. Costco is up 2.9% with nothing behind it but an ETF flow note and a chart post.
Movers with no story attached
Several names moved on nothing in this list. Modine is down 8.6% but only appears as a background holding in four GuruFocus 13F write-ups about other companies. NetApp is down 7.0% and shows up only as a line in an Invesco equal-weight ETF rebalancing piece. CAN is down 7.6% tagged to a Walter Bloomberg headline about France cutting its deficit to 3% in three years, which has nothing to do with the stock. SpaceX is down 2.8% across a batch of headlines covering Starlink restrictions for Ukraine's military, United expanding Starlink to half its flights, and a Barclays view that a Tesla-SpaceX merger could be announced before Tesla's annual meeting. The long tail of Dimensional, JPMorgan and Millennium 13F filings tagged to AAPL and SPCX is filing noise, not news about those names.
Hot CPI and an AI credit scare set the tape
The day's losses on your list are mostly one story. September CPI came in at 3.7% headline against 3.6% expected and 2.6% core against 2.5%, and the Nasdaq closed down 1.85% with the VIX up 10.5%. On top of that, the AI infrastructure complex got a credit scare: the Financial Times reported the yield on a CoreWeave bond maturing in 2032 hit nearly 15% on Tuesday, about 1.5 points higher over a week. CoreWeave has raised more than $35 billion this year and carried roughly $52 billion in debt and lease obligations at the end of June, with Q2 interest costs more than doubling to $640 million and debt around 5.8x annualised Q2 EBITDA. CreditSights analyst Jordan Chalfin told the FT the bonds sold off on fears its long data center leases outlast its shorter customer contracts: "If there's an overbuild, why would [customers] renew their contract with CoreWeave?" Visible Alpha consensus is about $25 billion of negative free cash flow this year. CoreWeave reports November 11.
RNTX down 23.7% with nothing behind it
Rein Therapeutics was the biggest fall on the list, down 23.7% to $0.5776 on 716,000 shares against a 421,000 average, closing at a new 52-week low. Nothing in the material explains it. The company is a 10-employee biopharma with LTI-03 in Phase 2 for idiopathic pulmonary fibrosis, $40.65 million of cash against a $49.8 million market cap and a trailing loss of $49.8 million. The last analyst action on file is HC Wainwright reiterating Buy with an $8 target back in August.
Neocloud and bitcoin-miner names take the brunt
Nebius fell 10.1%, called out alongside CoreWeave as the steepest Nasdaq 100 decliners. Two separate GuruFocus pieces tried to pin it on an insider sale and found little: the October 13 filing shows chief revenue officer Marc Boroditsky exercising 7,000 options at $40 and selling at $211.23 for $1,478,610 gross, under a trading plan adopted June 15, with 336,000 options still outstanding. Nebius raised more than $2 billion in a stock offering earlier this year. TeraWulf dropped 12.5% to $11.55 on 49.7 million shares versus a 30.3 million average, and the whole peer group moved together, Cipher -12.5%, IREN -12.3%, Core Scientific -12.5%, Hut 8 -10.5%. Nothing company-specific on WULF; Morgan Stanley actually raised its target to $65 from $62.50 on October 12 keeping Overweight.
VNET and XMTR fall hard without an explanation
VNET lost 14.9% to $4.4999, a new 52-week low against a $14.48 high, on volume slightly below average. The Yahoo page carries no news behind it, just the fundamentals: trailing revenue of 10.74 billion, a trailing net loss of 2.38 billion, debt/equity above 309%, and a consensus one-year target of $13.64. Xometry was down 12.0%, trading near $96 intraday against a $112.94 52-week high, also with no item explaining it and volume roughly in line with its average. The stock is still up about 62% year to date, and Rosenblatt raised its target to $120 from $110 in September.
ASTS downgraded by Piper Sandler
AST SpaceMobile fell 10.5%. Piper Sandler cut it from Overweight to Neutral and took the target to $54 from $98, a 44.9% reduction, on satellite-launch concerns. The economics in the article: June-quarter revenue of $31.5 million from gateway deliveries and government milestones against $119.1 million of adjusted operating expenses, roughly 3.8 times sales, with about $2.7 billion in cash, equivalents and restricted cash at June 30. Insiders sold $451.6 million of stock over the past twelve months against $0.8 million bought. A second GuruFocus item flags a GF Value of $583 versus the $47 price, but the piece itself calls that an extreme reading rather than a fair-value target given the company is unprofitable, and labels it a possible value trap.
Power and optics names caught in the same downdraft
Forgent Power Solutions fell 9.8% to $32.90, with JP Morgan having cut its target to $49 from $56 on October 9 while keeping Overweight; no fresh news. Coherent was down 9.3%, with the only item a GuruFocus DCF putting earnings-based intrinsic value at $52 against a $290 price, noting the stock is still up 57% year to date and 152% over the year, and that insiders sold $1.117 billion of stock over twelve months. NuScale Power fell 9.9%, with a headline-only Nasdaq piece simply noting it is now technically oversold. Vicor -8.2%, Astera Labs -7.8%, Generac -7.6% and Vertiv -6.2% round out the group; on Vertiv the only substance is a headline that RBC lowered its target to $323, and unusual option activity.
Oracle down 9% with Project Jupiter in focus
Oracle lost 9.0% to $130.54, now 56% below where it was a year ago and well off its $322.54 52-week high. Mizuho reiterated Outperform with a $320 target after attending a Doña Ana County Commission meeting where Oracle updated construction progress on Project Jupiter and discussed power infrastructure and regulatory hurdles. Oracle renewed its request for expedited FERC approval of the Green Chile pipeline, and Mizuho's clean energy team heard from a former BLM New Mexico State Director that the proposed pipeline reroute could avoid restarting environmental review. Mizuho sees no impact to FY2027 estimates. Investor Day is October 28. Separately, NetSuite launched QuickStart, a free accounting, AR/AP and subscription-management platform for eligible early-stage US tech startups with an AI assistant called Ask Oracle and usage caps including 2,500 records a month and four connected bank accounts.
Storage, memory and semis
NetApp fell 7.1% on a Barclays downgrade to Equal-Weight, part of a note that also cut HPE and Dell on enterprise AI spending trends; Dell was down 11.4% on the day. SanDisk fell 5.3% with a cluster of TradingView commentary centred on Chinese NAND competition, and Micron was down 3.9% despite headlines about a $35 billion buyback and a note that Micron and Nvidia together are expected to supply 9.8 points of the S&P 500's projected 27.2% Q3 earnings growth. TSMC fell 3.3% ahead of Thursday's results. Broadcom fell 3.1%, and the one piece of substance there is the CEO's warning that enterprise AI spending is still too experimental and often lacks measurable returns, comparing it to a kid burning through $10 of arcade tokens in ten minutes.
Netflix cutting 6% of staff
Netflix was essentially flat on the day, up 0.2%, but the news flow is heavy: around 1,000 job cuts, about 6% of the workforce, its biggest layoff since 2022, a week before earnings, with the stock down roughly 40% over the past year. Several items tie it to slowing growth and rising US churn, and one quotes the co-CEO from earlier this month saying the company is not growing as fast as he wants.
The green side
Little of size. Nurix was the best gainer at +6.8%, on a headline-only SWOT piece drawn from its 10-Q citing financial challenges alongside the pipeline. Intuit +3.0% and Axsome +3.7% on an RBC reiteration, Incyte +2.8% with Truist raising to $115, Revolution Medicines +2.8% with RBC raising to $260 and an 8-K on a new financial obligation, Costco +2.9%, Marathon Petroleum +1.6% with target raises from Wells Fargo to $560 and Citigroup to $518, and Accenture +0.7% after an investor day where it gave guidance the coverage described as strong. All headline-only.
OpenWorld drops on an amended filing
OpenWorld is down 16.1%, the largest move on the list, against a headline-only item: an 8-K/A on EDGAR covering Item 9.01, financial statements and exhibits. Nothing in the material explains the size of the move.
Nutriband funds the AVERSA patch
Nutriband is up 11.5% after announcing on October 13 that it raised $1.75 million through the exercise of 272,671 NTRBW warrants at $6.43 per share, which cleared out all remaining tradeable warrants following their September 30 expiration. The money is earmarked for clinical development and the FDA submission of AVERSA, its abuse-deterrent fentanyl patch, which the article says could generate $80 million to $200 million in annual US sales if approved. The GuruFocus piece around it flags the company's price-to-sales ratio at 43.65 against a historical median near 28.4, an Altman Z-Score of 36.61 and debt-to-equity of 0.04, a GF Score of 52 out of 100, and a GF Value estimate of $2.87 per share. Market cap is $71 million, and the company remains unprofitable with an operating margin worse than -435%.
AST SpaceMobile downgraded on SpaceX launch risk
AST SpaceMobile fell 8.5%, and six separate items all trace to one cause: Piper Sandler's Alexander Potter cut the stock from Overweight to Neutral and took his target from $98 to $54, roughly a 45% reduction. His reasoning is lower conviction on the pace of AST's 2026 and 2027 satellite launches, driven by SpaceX's push into direct-to-cell, including its roughly $8 billion commitment to acquire mobile spectrum. Piper's view is that SpaceX could in theory restrict launch availability for carrier-aligned partners like AST, undercut pricing, or bring its own devices. One of the write-ups says Piper now models only 18 operational satellites by end-2026 against a prior 45, pushing commercial service into the second half of 2027. Piper kept a constructive longer-term stance past 2027, arguing SpaceX's aggression raises carrier urgency to partner with an independent provider. For context the articles cite: June-quarter revenue of $31.5 million against $119.1 million in adjusted operating expenses, about $2.7 billion in cash, cash equivalents and restricted cash at June 30, a GF Score of 44/100, and insider net selling of about $450.8 million over the past twelve months. Next earnings are mid-November. The GuruFocus valuation piece notes the stock sits in a 52-week range of $47.57 to $133.86, down 25.4% on the week and 35.2% year to date, and labels it a possible value trap despite a GF Value of $583.31.
SpaceX itself down on Starlink and Ukraine headlines
SpaceX is down 4.2%, and the headline-only items on it point in two directions at once. Several concern Starlink limitations affecting Ukraine's ability to down Russian drones, with Kyiv said to be in contact with the US, SpaceX and NATO for clarification. Separately, Morgan Stanley's Adam Jonas reiterated Overweight with a $300 target, citing a Distributed Inference Cloud as an overlooked growth driver, and there are headlines on an FAA request for more Starship launches at the South Texas site, a United Airlines Starlink fleet rollout, and ETF net selling on October 12. These are headlines only, so there's no detail behind them beyond what they state.
Axsome sold off, RBC defends
Axsome is down 5.8%. RBC Capital reiterated Outperform with a $295 target, noting the stock has fallen roughly 28% over the past month against a 6% decline in the XBI, which the firm attributes to weaker-than-expected prescription trends. RBC argues those trends reflect seasonality and sampling dynamics rather than launch weakness, says the shares now trade about 15% below where they were before the Alzheimer's agitation approval, and continues to model a $2.3 billion agitation opportunity in 2035. The article notes the stock at $156.32, down 14% year to date. It also recaps recent coverage: Q2 2026 revenue of $218.4 million against H.C. Wainwright's $211.1 million estimate, a net loss of $0.99 per share, Mizuho at $316, H.C. Wainwright at $290, and Truist initiating at Buy with $285.
Cognition and Codexis both down 6.4%
Cognition Therapeutics closed at $0.8017, down 6.44%, on volume of 3.73 million shares against a 520,740 average. The Yahoo page shows no news driving it, just the price data, a 52-week range of $0.55 to $2.00, $34.01 million in cash and a trailing net loss of $16.77 million. Codexis is down 6.38% alongside a Form 144 filing notice dated October 14, which is a proposed-sale notice; the item carries no detail on size or seller.
Navitas up on nothing in particular
Navitas rose 4.6% to $10.45. The only item is a GuruFocus valuation piece with no news hook, which notes a GF Value of $3.01 against that price, a GF Score of 63/100, a 52-week range of $6.85 to $34.17, and insider selling of $150.7 million over twelve months with no buying.
Oracle up 4.2% on Project Jupiter and a product launch
Oracle gained 4.2% to $143.20 with several items behind it. The most substantive: Oracle has renewed its push for FERC to expedite approval of the 17.8-mile Green Chile pipeline, which would carry about 400 million cubic feet of gas a day to power the Project Jupiter data center campus in New Mexico via Bloom Energy fuel cells and an off-grid microgrid. The pipeline's timeline has already slipped to February 2027 from an initial August target after local opposition forced Transwestern, an Energy Transfer subsidiary, to reroute onto federal land. Environmental groups and New Mexico Attorney General Raúl Torrez want FERC to widen its review to cover the data center and pipeline together. Oracle told FERC the four-building campus should support nearly 5,800 peak construction jobs and up to $1.1 billion in annual economic output for Doña Ana County. Mizuho reiterated Outperform with a $320 target after attending the Doña Ana County Commission meeting, said regulatory approvals are still outstanding but kept a constructive view, and sees no impact to FY2027 estimates. Oracle's Investor Day is October 28. Separately, Oracle NetSuite launched QuickStart, a free financial platform for eligible early-stage US tech startups with accounting, banking, AR/AP and subscription management, an AI assistant called Ask Oracle, Claude and ChatGPT connectivity via Model Context Protocol, and built-in MRR, burn and runway metrics, with usage caps including 2,500 new records and 800 emails per month. A Deutsche Bank note groups Oracle with Alphabet, Amazon, Meta and Microsoft as spending nearly $800 billion in capex this year, with annual spending potentially above $1 trillion through 2030, and raises the risk of an "AI air pocket" where spending precedes revenue. Headline-only items add a Marvell/Microsoft/Oracle security working group and rising implied volatility in Oracle options.
Memory and semis under pressure
Micron is down 3.6% with a cluster of headline-only items, including a reported $35 billion buyback announcement, a broad memory and storage selloff, and various technical pieces. SanDisk is only down 0.3% on the main listing despite a heavy volume of commentary, though a separate chart item flags the Toronto line down 9.7%. Arista is down 3.0%, with headlines noting CEO Jayshree Ullal sold $34.4 million in stock and option activity. These are headline-only, so there's no reasoning behind them beyond what each line states.
Refiners and the rest
Marathon Petroleum rose 4.0% and headlines note an all-time high and a Citigroup price target raised to $518. Take-Two is down 4.1% and Xenon down 3.9%, both on headline-only items with no stated cause. Everything else on the list is inside two percent, including Apple at +0.1% despite a long run of HomeView smart display headlines, Netflix at -0.2% with a Huber Research double downgrade and Spain 2030 World Cup rights both in headlines, and TSMC at +0.2% ahead of Thursday earnings. Nothing there needs a second look today.
VerifyMe/OPNW down 17.3% on no visible news
OPNW was the biggest mover on the list, down 17.3%, but the two items attached to it are bare Form 4 filings for VerifyMe insiders Gerard Hernandez (Chief Accounting Officer) and CEO Matthew Shaw, both dated 30 September. The Investing.com pages carry nothing beyond the filing titles, no share counts, prices or transaction types. So there's no stated explanation here for the drop, and if you want one you'd need to go to the filings themselves.
Nutriband warrant cash
Nutriband rose 12.7%. The company said on 13 October it raised $1.75 million by exercising 272,671 NTRBW warrants at $6.43, which clears out all remaining tradeable warrants after their 30 September expiry. The money goes to clinical development and the FDA submission for AVERSA, its abuse-deterrent fentanyl patch, which GuruFocus notes could carry $80m to $200m in annual US sales if approved. The same piece flags the other side: price-to-sales of 43.65 against a 28.4 historical median, no meaningful P/E on negative earnings, operating margin worse than -435%, GF Score 52/100, though balance sheet strength is good with an Altman Z of 36.61 and debt-to-equity of 0.04. Market cap $71 million.
AST SpaceMobile downgrade, SpaceX the cause
ASTS fell 8.4%, and five separate items all trace to one note. Piper Sandler's Alexander Potter cut the stock from Overweight to Neutral and the target from $98 to $54. His reason is reduced conviction on the pace of satellite launches in 2026 and 2027, driven by SpaceX's direct-to-cell push, specifically Friday's roughly $8 billion commitment to buy mobile spectrum. Potter's argument is that SpaceX could restrict launch availability for carrier-aligned partners like AST, undercut mobile operator pricing, or bring out its own devices. GuruFocus adds the detail that Piper now models just 18 operational satellites by end-2026 versus a prior 45, pushing commercial launch into the second half of 2027. Piper stayed constructive beyond 2027 on the view that SpaceX aggression raises carrier demand for an independent provider. Context in the same coverage: the stock was at $51.46, 62% off its $133.86 high and down 18% on the week, with targets across the street spanning $42.50 to $108. Recent contrary calls include Deutsche Bank's upgrade to Buy at $93 on spectrum value and Berenberg initiating Buy at $92, against B.Riley cutting to Neutral at $65 and William Blair trimming its 2027 revenue estimate to $459m from $752m on launch delays. Insider selling at ASTS has been heavy, $451.6m sold against $0.8m bought over twelve months.
SpaceX itself off 4.1%
SPCX fell 4.1% on a crowded but headline-only feed: an FAA application for more Starship launches at the South Texas site, a CRS-35 launch, United expanding Starlink to its 737 MAX 8 fleet with completion expected before end-2027, Bernstein downgrading AT&T on Starlink competition, Amazon's satellite internet plan, an X/Grok subscription repriced from $90 to $30 a month, and $91.5m of ETF buying on Friday. None of these were read in full, and none is identified as the reason for today's move.
Cognition Therapeutics falls despite patent grant
CGTX was down 6.6% even though the news of the day was positive. The USPTO granted US Patent No. 12,759,979 covering a crystalline polymorph of zervimesine, its lead candidate, plus the production process and methods of treating Alzheimer's, dry AMD and dementia with Lewy bodies. Natural expiry 2045, with up to five years of possible extension on FDA approval. CMO Anthony Caggiano said the form has a better pharmaceutical and physiochemical profile suited to Phase 3-scale manufacturing. The company meets the FDA next week to settle endpoints for its registrational DLB programme and plans to start manufacturing the new form in Q1 2027 if that goes well. The articles don't say why the stock fell; the Yahoo chart item shows volume at 5 times the 20-day average and a 14.9% drop over five days.
Planet Labs insider sale and valuation flag
PL was down 5.1%. Director Ita Brennan sold 11,500 Class A shares on 1 October at a weighted average $16.3025, $187,478 in total, under a 10b5-1 plan adopted in January; she retains 250,373 shares. The stock has since gone to $15.96, down 14% on the week and 53.5% over six months. Background in the same piece: fiscal Q2 2027 came in at $116.1m revenue and adjusted EPS of $0.02 against expectations of $104.54m and a $0.02 loss, up 58% year over year on defence and intelligence demand plus a satellite-services handover, but Q3 guidance landed 10% below consensus. Needham cut its target to $40 from $53 on revenue timing while keeping Buy. A separate GuruFocus note on the prior session's 7.1% fall puts GF Value at $5.64 versus the $15.96 price, and counts $46.8m of insider selling over twelve months with no buying.
Navitas up on second Nvidia power board
NVTS rose 4.9%. It announced a 24 kW power delivery board converting 800 VDC straight to 12 VDC in a single stage, cutting out the 50 V intermediate bus converter, developed with Nvidia for the MGX ecosystem. Targets are 97% efficiency at full load and density above 2,000 W/in³ in a 400 mm by 60 mm form factor, using 16 NV6034 GaNFast FETs in a stacked half-bridge. It follows an earlier 20 kW, 800 V-to-6 V board also done with Nvidia, and will be shown at OCP Global Summit 2026. GuruFocus notes P/S of 61.67 against an 18.4 median, GF Score 63/100, EPS of -1.33, and $150.7m of insider selling over the past year with no buying.
Oracle and the AI capex question
ORCL gained 4.4%. The substantive piece is Deutsche Bank's AI research note, which puts Alphabet, Amazon, Meta, Microsoft and Oracle on course for nearly $800bn of capex this year and possibly over $1 trillion annually through 2030. It estimates an AGI-scale training run could need $300bn to $500bn of infrastructure and about 6 GW of power, or roughly 7.8 million Vera Rubin chips and 26 GW if compressed into four months, around $900bn at today's prices, possibly $200bn by 2030 on efficiency gains. The bank also points out the investment case doesn't need superintelligence: enterprise AI adoption is running about three times faster than the mobile, internet and cloud waves, with non-China AI revenue possibly above $200bn in 2026 against under $1bn in 2022. The risk it flags is funding on expected rather than earned revenue, what DeepMind's Jasjeet Sekhon calls an "AI air pocket." Separately and headline-only, Marvell, Microsoft and Oracle have formed a security working group, and there's a note on rising implied volatility in Oracle options.
Memory and semis sold off
The chip complex was the day's shared drag. MU fell 3.7%, with a cluster of headlines including a flagged sector-wide selloff listing Western Digital -6.5%, Seagate -6.1%, SK Hynix -4.8%, Micron -4.7% and SanDisk -4.1%, plus Cathie Wood flagging memory chip risks and a buyback authorisation lifted to $35.16bn. ANET was off 3.1%, with a chart item showing a 5.4% move at 1.7 times its own ATR20 on below-average volume. SNDK was roughly flat at -0.3% despite the noise, and had an S&P upgrade to BBB on AI memory demand. AVGO was up 0.8% and TSM up 0.2%. TSEM rose 2.6% on a headline about expanded SiGe capacity with Semtech. All of these are headline-only.
Quieter names worth a glance
Marathon Petroleum rose 4.1% and headlines note an all-time high at $470.42 and a Barclays target raised to $488. Take-Two fell 4.0%, with nothing attached beyond a chart item showing the move at 1.9 times its ATR20. Xenon Pharmaceuticals hit a 52-week low at $35.04, down 3.7%. Rocket Lab was off 2.2% with CFO Adam Spice selling $9.9m of stock. Adobe slipped 0.8% after HSBC downgraded it on open-source and AI competition, target cut to $267. Netflix was essentially flat at -0.2% despite a busy feed: a double downgrade at Huber Research on engagement and pricing, a KeyBanc target cut to $85, and exclusive FIFA 2030 World Cup rights in Spain and Andorra. Apple was flat at +0.1% on a long run of HomeView smart display and Apple TV 4K launch items plus a JP Morgan target raise to $360. Everything else on the list moved under 3% and carries routine filings, ETF flow notes and maintained ratings.
TMC leads the watchlist down
TMC the metals company fell 14.2% on Yahoo's close, about 1.6 times its own 20-day ATR and on 13.3 million shares against a 5.4 million average, taking it to a new 52-week low of $2.87 against a high of $10.87. The Yahoo page offers no specific trigger for the day's drop. What it does note is that the most recent company catalyst was the appointment of former ExxonMobil Upstream president Liam Mallon to the board in late September, which briefly lifted sentiment, and that coverage since has stayed on the same three issues: NOAA permit approvals, project execution, and funding. The company is still pre-commercial with no revenue, a trailing net loss of $305.6 million, a $20.6 million loss in Q1 FY26, and $98.7 million of cash. Market cap is $1.27 billion, the one-year average analyst target on the page is $10.90, and the stock is down 53.3% year to date.
VerifyMe insider filings, no detail
OPNW is down 11.0%, and the only two items on it are Form 4 notices from Investing.com for VerifyMe Inc covering 30 September, one for Chief Accounting Officer Gerard Albert Palana Hernandez and one for CEO and director Matthew Ian Shaw. Both pieces are filing stubs with no share counts, prices, or transaction types in the text, so there is nothing behind the headline to tell you whether these were sales, grants, or vesting.
Coherent drops on no stated news
Coherent fell 7.9% to $288.02, and the GuruFocus note covering it is a valuation piece rather than an event story, with no company news cited. Its figures: GF Value of $103.44 against the current price, which it labels 178.4% overvalued and "Significantly Overvalued"; a GF Score of 78/100 with growth at 9/10 and momentum 9/10 but valuation at 1/10; a trailing P/E of 70.0 versus a five-year median of 76.6 and a forward P/E of 30.7. It also flags $1,117 million of insider selling over the past twelve months with no insider buying, and 13 gurus holding, 3 adding, 12 trimming. The 52-week range is $108.19 to $440.00.
SoundHound to new lows
SoundHound AI closed down 7.8% at $4.97, a fresh 52-week low, on 20.3 million shares against a 26.9 million average, so the move came on below-average volume. Yahoo's summary attributes the pressure to cash burn, dilution, and the LivePerson acquisition, with revenue growth decelerating from 120.5% to 54.6%. Trailing revenue is $203.2 million with a net loss of $136.8 million and $202.8 million of cash. The most recent analyst action listed is Piper Sandler on 22 September, maintaining Neutral and cutting its target from $7 to $6, against an average target of $12.57. Earnings are set for 5 November.
Navitas falls despite the NVIDIA board
Navitas is down 7.3% even though the news flow on it was positive. On 12 October it announced a 24 kW power delivery board developed with NVIDIA that converts 800 VDC directly to 12 VDC in a single stage, eliminating the 50 V intermediate bus converter. It targets 97% efficiency at full load and over 2,000 W/in³ in a 400 mm × 60 mm form factor, uses 16 NV6034 GaNFast FETs in a stacked half-bridge, and builds on an earlier 20 kW 800 V-to-6 V board also done with NVIDIA. It will be shown at NVIDIA's MGX partner display at OCP Global Summit 2026. Shares rose about 5% in after-hours trading on that announcement, so the 7.3% decline in the live quote is a reversal of that reaction. One headline-only item lists semiconductors among Monday's sector laggards. GuruFocus separately puts NVTS on a P/S of 61.67 against a 18.4x historical median, a GF Score of 63/100, GF Value of $3.01 versus a $9.99 price, and $150.7 million of insider selling over twelve months with no buying.
Credo sells the news at OCP
Credo is down 7.3%, and Investing.com gives a direct explanation. The company unveiled a 1.6T ZeroFlap active light cable at OCP Global Summit, an optical interconnect for AI scale-out that draws roughly 30% less power than comparable active electrical cables and reaches 50 metres, but commercial shipments are not expected until 2027, and the market treated it as sell-the-news. Adding to it: early-October insider sales by the CTO, COO and others, all under pre-arranged Rule 10b5-1 plans tied to tax on vested equity, plus price target cuts from Stifel and Mizuho that kept bullish ratings. The Nasdaq was down 0.4% on Micron's CXMT-driven decline, and Credo's beta of about 3.25 amplifies that. Shares opened at $212.22 and touched $201.81. A Form 4 for COO Yat Tung Lam covering 30 September is also on the list with no detail in the body. GuruFocus, on the same day, reads the other way: price $200.84 against a GF Value of $273.67 for 26.6% undervalued, GF Score 84/100, P/E 71.7 against a five-year median of 131.3, but $447.1 million of insider sales over twelve months with no buying.
Planet Labs down 7.1% with a director sale
Planet Labs fell 7.1% to $15.96, now down 14% over the past week and 53.5% over six months. Director Ita Brennan sold 11,500 Class A shares on 1 October at a weighted average $16.3025, totalling $187,478, under a 10b5-1 plan adopted 14 January 2026, leaving her with 250,373 shares. The background in the same piece: fiscal Q2 2027 came in at $0.02 adjusted EPS on $116.1 million revenue versus expectations of a $0.02 loss on $104.54 million, revenue up 58% year over year on defence and intelligence demand plus a satellite-services handover that pulled in point-in-time revenue; Q3 guidance was 10% below consensus while the full-year outlook was nudged up. Planet also won a €25 million contract from the German Federal Ministry of the Interior. Needham cut its target to $40 from $53 on revenue timing while keeping Buy; Citizens stayed at Market Perform. GuruFocus has GF Value at $5.64 against the $15.96 price, a GF Score of 60/100, and $46.8 million of insider selling over twelve months with no buying. A Form 4 stub for Brennan dated 1 October is also listed.
Red Cat consolidates its drone units
Red Cat is down 6.6%. On 12 October, at the AUSA annual meeting, it announced Red Cat Aerial, a new division pulling together Teal Drones and FlightWave Aerospace, and introduced the TRICHON, a hand-launched VTOL tricopter aimed at ISR missions for military customers. GuruFocus puts the stock at $5.77 with a $881 million market cap, a P/S of 9.75 against a 13.4x historical median, and a GF Score of 70/100: financial strength 8/10 with a current ratio of 14.86 and debt-to-equity of 0.03, growth 9/10 on 45.8% three-year revenue growth, but profitability 3/10 with operating and net margins worse than -130%. GF Value of $22.10 carries the label "Possible Value Trap, Think Twice." Insiders sold roughly $7.4 million over twelve months, including 600,000 shares in the last three, with no purchases.
Memory names sell off together
SanDisk is down 6.0% and Micron 3.9%, and they moved as a group. Investor's Business Daily reports Micron, Sandisk and SK Hynix all selling off Monday while the Dow rose on JPMorgan and Goldman Sachs earnings, with the Nasdaq slipping. The specific driver named in the Micron headlines and in the Credo article is competitive pressure from China's CXMT in memory. Cutting the other way on SanDisk, headline-only items report S&P upgrading it to BBB on AI memory demand driving cash flow past $23 billion, and Goldman flagging a new AI-memory opportunity, with a further headline simply asking why the stock is sliding. On Micron, headlines note a buyback authorisation raised to $35.16 billion, strong Q4 revenue on AI demand, and Cathie Wood flagging memory chip risks. A TradingView post calling SNDK oversold near $1,430 is one retail trader's view, not analysis. One headline also notes global smartphone shipments fell 20% in Q3 to their lowest third-quarter level since 2012, with Counterpoint citing AI data centres absorbing memory chip supply.
Broadcom and the AI funding warnings
Broadcom is down 1.9% against a cluster of headlines all pointing at the same thing: CEO Hock Tan warning that capital, not chips, is becoming AI's bottleneck, with commentary on OpenAI revenue and rising debt insurance costs. IBD reports chip stocks falling as both Broadcom's and Intel's CEOs warned about AI funding. Arista is down 2.7% with a headline tying it to Ethernet moving into Nvidia's rack, and Oracle down 2.8% with headlines on its AI power constraints and the stock trading below a director's $3.5 million purchase price. These are headline-only items, so the reasoning behind each is not available beyond what the lines state.
Downgrades and target changes
Adobe, down 1.7%, drew two separate downgrades: HSBC on open-source competition, and Wells Fargo cutting to a lower rating with a $225 target, citing growth concerns. AST SpaceMobile, up 1.0%, got contradictory calls, a Deutsche Bank upgrade to Buy at $93 and a Piper Sandler downgrade to a $54 target on launch concerns. Elsewhere: RBC raised Datadog's target to $320 on a higher growth forecast with the stock down 2.0%; TD Cowen initiated TeraWulf at Buy and Morgan Stanley set $65 while the stock fell 2.9%; Barclays and Evercore both raised Marathon Petroleum targets, to $488 and $420, with MPC up 0.8%. All headline-only.
SpaceX headline cluster
SPCX is barely moved at +0.5% but carries the heaviest headline count in the list. The substance across those lines: a reported $8 billion spectrum purchase to expand wireless reach, Pivotal Research raising its target to $230 from $220 on the spectrum deal and authorisation for 15,000 satellites, Bernstein downgrading AT&T specifically on Starlink competition, and Amazon announcing a satellite internet plan aimed at Starlink. Morgan Stanley is cited on Starship Flight 15. None of these were read in full.
Apple quiet but well covered
Apple is up 1.3%. The named items are a JP Morgan target raise to $360, BofA reaffirming Buy as iPhone 18 Pro shipping times tighten, reports of foldable iPhone orders raised by 30%, and Tim Cook meeting Chinese Vice Premier He Lifeng. Most of the remaining Apple lines are routine ETF creation and redemption notices from GuruFocus rather than company news.
Smaller movers worth a glance
Joby is down 5.5% on a CEO disposal of $93,944 of shares, Tower Semiconductor down 5.3% alongside a headline on expanding its SiGe capacity deal with Semtech for AI, Nebius down 5.0% despite a letter of intent for a Rotterdam AI gigafactory, Nokia down 4.4% with a headline on selling its Enterprise Campus Edge division, and Rocket Lab down 3.7% with a CFO Form 4. All headline-only. The rest of the list, including Accenture, Costco, Netflix, Aflac and Avery Dennison, moved less than 1.5% on routine notes.
TMC leads the watchlist lower
TMC was the worst name on the list, down 14.0% to $2.88 on 13.1 million shares against a 5.2 million average, setting a new 52-week low at $2.87 (range top is $11.35). Yahoo's summary is explicit that the recent news flow is not about operations or earnings: the main catalyst it names is a board addition, former ExxonMobil Upstream president Liam Mallon, with the rest of the coverage framing the stock as a permit-dependent deep-sea mining story. The stock is down 53.3% year to date and 67.6% over a year, against a 1-year target estimate of $10.90, and Maxim Group's June 4 Buy initiation at $10 is the most recent rating action shown. Three separate Form 4 items appeared for TMC covering 10, 11 and 12 October, but the Investing.com pages carry only the filing titles, no transaction detail, so there's nothing to say about who traded or how much.
SoundHound at a 52-week low
SOUN fell 7.7%, closing near $4.985 after touching $4.96, which is the 52-week low, versus a $22.17 high. Volume was actually light at 18.7 million against a 27.1 million average. The Yahoo summary says recent coverage is centred on cash burn, share dilution, and the market waiting for the first set of results that include LivePerson. For context from the same page: Q2 FY26 revenue was $61.9 million with a $42.8 million loss, trailing revenue $203.2 million, cash $202.8 million, levered free cash flow negative $45.5 million. Piper Sandler maintained Neutral on 22 September and cut its target from $7 to $6. Next earnings 5 November.
Credo sells the news at OCP
Credo was down 7.4%. The Investing.com piece attributes it to a sell-the-news reaction: Credo unveiled its 1.6T ZeroFlap active light cable at the OCP Global Summit, an optical interconnect for AI scale-out networks drawing roughly 30% less power than comparable active electrical cables over distances up to 50 metres, but commercial shipments aren't expected until 2027. On top of that, the CTO, COO and other executives sold millions of dollars of stock in early October under pre-arranged 10b5-1 plans tied to tax on vested awards, and both Stifel and Mizuho trimmed price targets while keeping bullish ratings. Shares opened at $212.22 and touched $201.81 intraday. The article notes Credo's beta near 3.25, which amplifies sector moves, and ties the weakness to a soft Nasdaq session driven in part by Micron's decline on competition from China's CXMT.
Memory complex: SanDisk, Micron, the sector read-across
SNDK fell 6.0%, and four items cover it from different angles. The move itself is attributed to pre-earnings risk reduction ahead of the 29 October call, an overnight selloff in Seoul memory names that followed a preliminary revenue miss from Samsung, and a technical break below the 200-day moving average last week that has since acted as resistance. The open question is margin durability: fiscal Q4 revenue rose 51% sequentially to $8.97 billion with gross margin at 84.6%, and management said about two-thirds of the revenue growth came from pricing. Guidance for fiscal Q1 is $10.3 to $10.8 billion. GuruFocus sets that against the fiscal 2023 downturn, when the business inside Western Digital saw sales drop 38% to roughly $6.1 billion, per-gigabyte ASPs fall 39%, gross margin collapse from 33.3% to 7.1%, and a loss near $2.1 billion. Separately, Goldman's high-bandwidth flash thesis has HBF at 9% of global NAND wafer capacity but only 4% of bit shipments by late 2028, roughly a 2.25-to-one ratio of capacity consumed to bits shipped, which GuruFocus reads as raising the bar for returns; SanDisk and SK hynix published an OCP technical spec on 3 August with Google and Tenstorrent involved in validation. Stock sits about 36% below its $2,354.39 high; Mizuho raised its target to $2,050 on 6 October and consensus is near $2,120. Micron itself was down 3.7%, with a headline citing competition from CXMT, and NVTS was down 7.4% on a headline-only Nasdaq sector-laggards piece naming semiconductors. Broadcom, down 1.8%, has a thick headline cluster around Hock Tan saying the biggest AI constraint is capital rather than memory chips. These are one line each; the Credo and SanDisk full reads above are where the actual sector detail is.
Red Cat consolidates drones, stock still down
RCAT fell 6.2% on the day it announced Red Cat Aerial, a division merging Teal Drones and FlightWave Aerospace under one brand alongside existing Black Widow, FANG, Edge 130 and Hellcat platforms, plus a new hand-launched VTOL tricopter called TRICHON aimed at ISR missions. It's being shown at the AUSA annual meeting in Washington through 14 October, with the Blue Ops maritime arm demonstrating its Variant 7 uncrewed surface vessel on the Potomac. The GuruFocus piece adds the uncomfortable half: market cap $881 million, P/S of 9.75 against a 13.4x two-year median, GF Score 70 with financial strength 8/10 and profitability 3/10, current ratio 14.86 and debt-to-equity 0.03, 3-year revenue growth 45.8%, but operating and net margins worse than -130%. Insiders sold about $7.4 million over twelve months with no purchases, including 600,000 shares across six transactions in the last three months, and GuruFocus labels its own $22.10 GF Value against the $5.77 price a "possible value trap." A Form 4 dated 11 October is listed with no detail in the body.
Insider-sale cluster across the mid-caps
A large share of today's headline-only flow is routine Form 4 and insider-sale items, and several of the day's decliners sit in it. Astera Labs was down 5.0% with repeated headlines that director Stefan Dyckerhoff sold $4.7 million in shares, plus Form 4s for 10, 11 and 12 October and a note that ETFs were net sellers on 8 October. Joby fell 5.5% with headlines on CEO JoeBen Bevirt disposing of $93,944 and the chief policy officer selling $30,645. Arista, down 2.6%, carries headlines that CEO Jayshree Ullal sold $21.06 million. Generac, down 3.1%, and Si-Bone, up 3.3%, both have officer sale headlines. Nebius was down 5.1%, with a headline saying the stock slipped despite a letter of intent for a Rotterdam AI gigafactory, and a Volozh Form 4. These are titles only, with no transaction context behind them beyond what the headline states.
Ratings moves worth a glance
Adobe, down 1.7%, was downgraded by Wells Fargo on growth concerns with the target cut to $225, which multiple outlets carried. On the positive side, Butterfly Network rose 3.7% and Canaccord Genuity initiated at Buy. AST SpaceMobile was up 1.0% after a Deutsche Bank upgrade to Buy with a $93 target. RBC raised Datadog to $320 on its revenue outlook, with the stock down 1.6%. TeraWulf, down 2.8%, drew a TD Cowen Buy initiation and a Morgan Stanley target raise to $65. Evercore raised Marathon Petroleum to $420 and Amphenol to $100, and trimmed Vertiv to $325. All headline-only.
The rest
SpaceX, up 0.4%, has by far the longest headline tail on the list, mostly around the reported $8 billion spectrum purchase, Starlink's push into India against Reliance Jio, and Pivotal Research raising its target to $230 from $220 on the mobile network plans; none of it was read in full. Apple, up 1.2%, has a similarly long but low-substance tail dominated by ETF flow items, with the more interesting headlines being increased foldable iPhone orders and Counterpoint data showing global smartphone shipments down 20% in Q3 as AI data centres absorb memory supply. Everything else on the list moved less than about 2% and carries nothing beyond a headline.
