Butterfly Network leads the fall on a filing with no content
BFLY is down 14.9%, the largest move on the list, and the only item attached to it is a Form 144 notice dated 31 October. Form 144 is a notice of proposed insider sale, but the piece carries no share count, no seller name, and no commentary, so there is nothing in the material explaining the size of the drop.
SanDisk down 13.5% despite a blowout quarter
SNDK is off 13.5%, and four separate TradingView write-ups all cover the same puzzle: the numbers were very strong and the stock sold off anyway. Fiscal Q1 2027 revenue came in at $11.03 billion, described as up 23% quarter over quarter (one of the four authors instead writes 378% year over year), with GAAP net income of $8.1 billion and non-GAAP EPS of $49.51. Data-center revenue rose 61% quarter over quarter to $4.8 billion, Q2 guidance is $12.2 to $12.6 billion, and the company announced an 8-for-1 forward split with adjusted trading expected to begin 20 November. The authors attribute the sell-off to positioning and expectations rather than the results, with one noting the stock had already run hard toward $1,900 to $2,000 and failed to hold it. All four are chart pieces rather than news, and all are bearish or cautious on structure, watching the $1,100 to $1,150 area as the level in question. Two of them carry promotional Bitget referral content, worth knowing before you weight them. Note the levels quoted are pre-split.
Datadog slides 11.5% into Wednesday's print
DDOG is down 11.5%, trading at $235.27 with a market cap of $84.5 billion, and has now fallen 16% over the past week even after a 67% six-month gain. The sell-off is happening against a wall of bullish broker notes ahead of third-quarter fiscal 2026 results due Wednesday 4 November. StoneX kept a Buy and a $330 target, which it calls a Street high, and expects beats on revenue, operating income, margin and free cash flow, citing the reset of the largest customer as a cleaner read on acceleration, security as a new platform pillar, AI monetisation widening beyond infrastructure, and healthy hyperscaler data points. Evercore ISI raised its target to $300 on Outperform, saying partners with practices over $10 million and customers spending in the millions reported tracking at or above plan, with consolidation wins taken from Dynatrace, New Relic and Splunk. Evercore models roughly $1.19 billion of revenue, 34% growth, against the FactSet Street figure of about $1.146 billion, or roughly 29.3% growth, and flags one watch item: some large AI-native customers are shifting logs and LLM evaluations onto cheaper stacks. Also referenced in the same pieces are UBS at $320, Rosenblatt at $305, Bernstein upgrading to Outperform at $350, and TD Cowen modelling about 35% growth against company guidance of 29%.
Tower Semiconductor reported, beat on revenue, and still fell 11.4%
TSEM is down 11.4%. Q3 adjusted EPS of $1.05 missed the $1.06 consensus by a cent, while revenue of $526.2 million beat the $522.1 million estimate and grew 33% from $395.7 million a year earlier. Gross profit nearly doubled to $178.8 million from $93 million, operating profit excluding one-offs was $127.1 million against $50.6 million, and adjusted net profit was $131.3 million. Q4 guidance of about $600 million plus or minus 5% is well above the $579.7 million consensus, a 36% year-on-year and 14% sequential increase at the midpoint. CEO Russell Ellwanger said the company is entering the strongest growth phase in its history, closing the year at $2 billion of revenue on a $2.4 billion annualised run rate, with silicon photonics alone targeted at a $1.1 billion annualised run rate in Q4, five times its 2025 SiPho revenue. Worth flagging the disconnect: one Investing.com piece reported shares up 4.5% premarket on the guidance, and a GuruFocus headline says shares rose 5% after the beat, but the live quote has it down 11.4%. The preview piece noted the stock was already 41% below its $319.94 high on a 73.67 forward P/E, with a consensus target of $312.93 and recent Buy initiations from Mizuho at $300 and Barclays at $310. A GuruFocus headline-only item points out GF Value of $52.92 against a $166.48 price.
Coherent down 11.3% after a premarket pop on the Marvell–Lumentum deal
COHR is off 11.3%, though the only full article on it describes the opposite move intraday: the stock was up 6.7% pre-open on news that Marvell is acquiring optical rival Lumentum in a $115 billion deal, with investors also positioning ahead of fiscal Q1 2027 results on 4 November where consensus sits near $1.93 EPS. The piece said the report would be watched for data-center demand, indium phosphide capacity and the PhotonLink platform, and noted Coherent's beta above 2. That deal shows up elsewhere in the list too, with Marvell down 10.05% and Lumentum down 8.57% in the quote strip attached to that article.
The broader AI and semis complex sold off together
This was a sector-wide day rather than a set of single-stock stories. Alongside the names above, ALAB is down 10.9% with only a Form 4 filing notice carrying no detail, NTAP down 8.8%, CRDO down 8.7%, ANET down 8.3% ahead of earnings with an Evercore ISI reiteration headline, TSM down 5.9%, AVGO down 5.5% despite a D.A. Davidson upgrade to Buy with a $400 target, MU down 5.3%, and APH down 3.4% even as Goldman Sachs added it to its US Conviction List with a Buy. IOVA is down 11.3% on a headline-only quant piece ahead of earnings. NBIS is down 10.4% with two director Form 4s and a couple of chart posts, RKLB down 7.4%, SNX down 7.2%. The market context in the article furniture: S&P 500 down 1.82%, Nasdaq down 2.86%, Dow down 1.09%, Intel down 28.58%, and oil off more than 4% on reported US-Iran talks.
Kosmos Energy the only real gainer, on a miss
KOS is up 6.3% and is the one meaningful advance here. The headlines say Q3 brought a $43 million loss on $410 million of revenue, missing on both EPS by three cents and revenue, following what one preview called a 200% stock rally. There are two 8-Ks, one on results and one covering a new material agreement and a direct financial obligation. One headline says the stock sank on the miss, which again sits against the live quote.
SpaceX, Oracle and the quieter names
SPCX is down 6.4% on a thick but headline-only cluster: talks to buy Boost Mobile or use its network from EchoStar per the Washington Post, EchoStar gaining premarket on it, a Trump post saying he has to protect Musk if SpaceX is at risk from Democrats, several Musk posts on Starlink and orbital compute, and a Telesat competition angle. ORCL is also down 6.4%, with a mixed shelf filing, a Stephens upgrade to Overweight with a $213 target, and several Form 4s, all headline-only. AU is down 6.2% as TD Cowen initiated with a buy on growth. The rest is routine: Apple down 1.2% ahead of after-the-close earnings with an enormous volume of headline chatter, mostly ETF flow notes and previews, plus a Lynx Equity warning on near-term supply shortages and pricing pressure easing by mid-2027. Axsome is up 0.7% on a Q3 beat with $259.7 million of revenue, and Netflix, PayPal and Avery Dennison are flat with nothing behind them.
OpenWorld's dilutive raise, down 25%
OPNW is the biggest mover on the list, down 25%. The company closed a registered direct offering on Friday raising roughly $3.5 million gross, placed with a single institutional investor through Maxim Group as sole placement agent. The structure is heavily dilutive for a stock this size: 1,494,084 common shares plus pre-funded warrants for another 1,023,901, and Series A and Series B warrants each covering up to 2,517,985 shares. It was priced at-the-market under Nasdaq rules. The article notes the shares were at $0.92 against a 52-week low of $0.91 and already down 44% over the prior week, and that the company carries a "WEAK" financial health score on InvestingPro. Company and insiders are locked up for 45 days. Background in the same piece: the VerifyMe merger, under which OpenWorld becomes a wholly owned VerifyMe subsidiary, has shareholder approval and has had its deadline pushed a third time, to October 31, 2026. There is also an 8-K filed covering a material definitive agreement and other events, headline only.
Butterfly Network and a Form 144
BFLY is down 14.9%. The only item is a Form 144 filing notice dated 31 October, and the article carries no detail beyond the fact of the filing, so there is nothing here explaining the move.
SanDisk down 13.5% despite a blowout quarter
SNDK fell 13.5% and dominates the list by volume of coverage. The quarter itself was very strong: September-quarter revenue of $11.03 billion against its own raised guidance of $10.3–10.8 billion, adjusted EPS of $49.51 versus guidance of $44.00–46.00, revenue up 378% year on year and 23% sequentially, GAAP net income of $8.1 billion, data-centre revenue up 61% quarter on quarter to $4.8 billion, and Q2 guidance of $12.2–12.6 billion. Management said roughly 60% of the sequential growth came from volume and 40% from pricing. An 8-for-1 forward split is set to take effect around November 20. The stated reason for the drop is competitor Kioxia: it guided to ¥2 trillion ($12.7 billion) operating profit against the ¥2.35 billion consensus of ¥2.35 trillion, and said NAND average selling prices rose in the mid-20% range in the September quarter, a sharp slowdown from 70% the quarter before, implying near-flat sequential pricing ahead. Weak Intel guidance and general AI-trade nerves are cited alongside it. Analyst notes went both ways, all headline only: Rosenblatt kept Buy with a $2,400 target, while Wells Fargo cut to $1,300 and RBC to $1,400. Four TradingView authors wrote the stock up, all bearish or cautious on the chart despite the numbers, working off a broken trendline and the $1,150–$1,300 band flipping from support to resistance, with the $1,100 area as the level they're watching.
Datadog down 11.5% with a CTO sale in the background
DDOG is off 11.5%. The insider filing is pre-arranged rather than discretionary: CTO and director Alexis Le-Quoc sold 43,224 Class A shares on October 28 for about $12.06 million at $275.73 to $284.81, under a 10b5-1 plan set up in June 2025, converting an equal number of Class B shares the same day. He still directly holds 488,033 Class A and 2,073,582 Class B, with 6,146,835 more Class B through his trust. The stock has since fallen to around $235. GuruFocus attributes the day's drop to the broad tech sell-off rather than anything company-specific, and the same article lists recent sell-side positioning ahead of the November 4 Q3 report: Rosenblatt Buy at $305, TD Cowen Buy looking for 35% growth, UBS at $320, Bernstein upgraded to Outperform at $350. Unusual Friday option activity was flagged in DDOG alongside TTWO and MCD.
The semis and AI-infrastructure complex sold off together
Most of the red here is one trade. Tower Semiconductor -11.4% (with a Q3 report pending), Coherent -11.3% (Morgan Stanley cut its target to $325), Astera Labs -10.9%, Nebius -10.4% on what GuruFocus frames as AI cloud expansion concerns, NetApp -8.8%, Credo -8.7%, Arista -8.3%, Rocket Lab -7.4%, TD Synnex -7.2%, SpaceX -6.4%, Oracle -6.4%, Micron -5.3%, Broadcom -5.5%, Vertiv -5.5%, TSMC -5.9%. All headline only. A widely-shared drawdown tally puts AVGO 31.9% below its June peak, SPCX 31.2%, GOOGL 30.4%, MU 26.1% and META 21.5%. On Oracle specifically there are several angles without full text: a piece on bull and bear cases weighing the AI backlog against the debt burden, a note on the funding ceiling excluding debt refinancing, and a GF Value read calling it undervalued after the fall. Broadcom got a D.A. Davidson upgrade to Buy with a $400 target on the same day it fell. A separate headline flags Blackstone warning that Anthropic may get a below-investment-grade rating after its planned IPO.
Precious metals names and the SpaceX noise
Gold and silver futures were sharply lower on the day the quoted articles were published, gold -3.63% and silver -6.20%, and the miners on your list moved with them: AngloGold -6.2% and Wheaton -5.4%, both flagged as entering oversold territory. On SPCX, the -6.4% comes with a cluster of headline items of varying seriousness, including Shotwell saying two million shares will be gifted to children's Trump Accounts, a piece claiming SpaceX relies on Anthropic for a third of its revenue, one on the SpaceX-Tesla deal facing a China problem, and Binance pointing to a large SpaceX stake after its hack. Several Musk posts in the list are promotional and carry nothing new.
The green side, mostly analyst-driven
Kosmos Energy is up 6.3% ahead of Q3 results on November 2. Stagwell +5.2% alongside an 8-K/A on officer departures and compensation, plus target raises to $12 from both Wells Fargo and B. Riley. Exelixis +4.8% with five target raises in one go: TD Cowen to $76, Morgan Stanley and Truist to $60, RBC to $58, Barclays to $54. Accenture +4.5% with ETF inflow noted. Comcast +4.3%. Incyte +3.1% on an Oppenheimer upgrade to Outperform at $144 and raises from RBC, Barclays and a cut from Wells Fargo to $127. PayPal is flat after a Q3 beat and raised 2026 EPS guidance.
Apple, and one item that doesn't square
Apple fell 1.2% but overtook Nvidia as the world's most valuable company during the tech sell-off. Other Apple headlines cover an Alibaba partnership to put Qianwen on devices in China, Cook defending the AI strategy, the Ascension Labs acquisition closing, and earnings positioning. The long run of BlackRock and AMUNDI 13F items tagged to AAPL in the list are unrelated to Apple itself. One to treat with care: a headline says Beam Therapeutics surged 64% after an InvestingPro call, but the live quote on the item shows BEAM down 5.6%, so that headline is not describing today.
SanDisk drops 13.5% despite a blowout quarter
The biggest story in the list by volume of coverage is Sandisk, down 13.5%. The fall came the day after results that beat its own raised guidance: September-quarter revenue of $11.03 billion against guidance of $10.3 to $10.8 billion, and adjusted EPS of $49.51 against $44.00 to $46.00. Revenue was up 378% year over year and 23% sequentially, with management attributing roughly 60% of the sequential gain to higher shipment volumes and 40% to pricing. Data-center revenue was $4.8 billion, up 61% quarter on quarter, GAAP net income $8.1 billion, and guidance for the December quarter is $12.2 to $12.6 billion. The company also announced an 8-for-1 forward split, with adjusted trading expected to begin around November 20. Investing.com ties the selloff specifically to competitor Kioxia: the Tokyo NAND maker guided to ¥2 trillion ($12.7 billion) operating profit this quarter against analyst estimates of ¥2.35 trillion, and said its average NAND selling price rose in the mid-20% range in the September quarter, a sharp slowdown from 70% the quarter before. That read-across on NAND pricing, plus weak Intel guidance and general AI-trade nerves, is the stated reason the whole memory group sold off.
SanDisk analyst notes split sharply
The sell-side reaction to the same print went both ways. Rosenblatt kept its Buy with the target unchanged at $2,400 and Susquehanna cut to $2,720, while Wells Fargo cut to $1,300 and RBC Capital to $1,400, roughly where the stock now trades. Four TradingView posts I read in full are all technical and all leaning bearish on structure despite the numbers, focused on whether the $1,100 to $1,150 area holds after the breakdown through the old $1,240 to $1,300 support. Worth noting those posts carry heavy exchange-referral promotion, and their levels are pre-split.
The memory and AI-infrastructure complex sold off together
Sandisk wasn't alone, and the Kioxia NAND warning plus the broader tech selloff shows up right across the watchlist. Micron fell 5.3%, Taiwan Semiconductor 5.9%, Broadcom 5.5%, Tower Semiconductor 11.4%, Coherent 11.3%, Credo 8.7%, Astera Labs 10.9%, NetApp 8.8%, Arista 8.3%, Vertiv 5.5% and Oracle 6.4%. These are headline-only items, mostly GuruFocus valuation notes and "why is X sliding today" pieces, so I can't give you the reasoning behind each. Of the analyst notes in the group, D.A. Davidson upgraded Broadcom to Buy with a $400 target, and Morgan Stanley cut Coherent to $325 with another firm at $262 on a Neutral. A widely shared post listed peak-to-date drawdowns across big tech, with Broadcom down 31.9% since June, SpaceX down 31.2% and Micron down 26.1%.
OpenWorld down 25% on a dilutive raise
OpenWorld fell 25% after closing a registered direct offering that raised about $3.5 million gross. The deal was priced at-the-market under Nasdaq rules to a single institutional investor, with Maxim Group as sole placement agent: 1,494,084 shares plus pre-funded warrants for 1,023,901 shares, and Series A and Series B warrants each covering up to 2,517,985 shares. That's a lot of potential new paper against a $3.5 million raise. The stock was at $0.92, near its 52-week low of $0.91, and down 44% on the week before the close. Insiders and the company are locked up for 45 days. Context in the same piece: VerifyMe shareholders have approved the merger that would make OpenWorld a wholly owned subsidiary, and the agreement deadline was extended a third time, to October 31, 2026. There's a matching 8-K on EDGAR covering the material agreement.
Datadog off 11.5% with a CTO sale in the filings
Datadog fell 11.5%, attributed by GuruFocus to the broad tech selloff rather than anything company-specific. Separately, CTO and director Alexis Le-Quoc sold 43,224 Class A shares on October 28 for about $12.06 million, at prices between $275.73 and $284.81, under a 10b5-1 plan set up in June 2025. He converted the same number of Class B shares that day, and still directly holds 488,033 Class A and 2,073,582 Class B shares, with a further 6,146,835 Class B through his trust. So it was a planned sale into strength, with the stock now at $235.29 after a 69% twelve-month return. Q3 results are due November 4, and the recent sell-side setup into it was positive: Rosenblatt Buy at $305, TD Cowen Buy looking for 35% growth, UBS raised to $320 and Bernstein upgraded to Outperform at $350. Unusual Friday options activity was flagged in DDOG alongside TTWO and MCD.
Butterfly Network, Nebius, Rocket Lab
Butterfly Network fell 14.9%. The only item is a Form 144 notice dated October 31, which flags a proposed insider sale, and the article carries no detail beyond that, so there is no stated reason for the move. Nebius dropped 10.4%, with GuruFocus citing the tech selloff and AI cloud expansion concerns, and a Form 4 showing director Arne Grimme bought 148 shares. Rocket Lab was down 7.4% with no news beyond chart commentary and a valuation note.
Smaller movers and the quieter names
TeraWulf fell 8.0%, with B. Riley cutting its target to $26 and an options-implied move of about 9.9% on next week's earnings. Pagaya dropped 7.6% even as TD Cowen raised to $27 and B. Riley to $38. Red Cat showed four separate director Form 4 filings for October 28, with the stock down 8.3%. On the upside, Kosmos Energy rose 6.3% ahead of Q3 results on November 2, Stagwell gained 5.2% with Wells Fargo and B. Riley both lifting to $12 and an 8-K on an officer change, and Exelixis rose 4.8% on a clean sweep of target raises from TD Cowen ($76), Morgan Stanley ($60), Truist ($60), RBC ($58) and Barclays ($54). Incyte added 3.1% with an Oppenheimer upgrade to Outperform at $144 and raises from RBC and Barclays, against a Wells Fargo cut to $127. Accenture rose 4.5%.
Apple quiet on the day, noisy in the list
Apple was down just 1.2% but dominates the item count, mostly because a long run of unrelated BlackRock and Amundi 13F stories is tagged to its ticker. The genuinely Apple-related headlines: it overtook Nvidia as the world's most valuable company during the tech selloff, it is reported to be partnering with Alibaba to integrate Qianwen into devices in China, Tim Cook defended the AI strategy, and it closed an acquisition of Ascension Labs. All headline-only. PayPal, Netflix and Avery Dennison were effectively flat; PayPal beat on Q3 and raised 2026 EPS guidance, and Avery Dennison's Q3 slides showed underlying growth ahead of the headline, with JP Morgan to $200.
SNDK drops 13.5% despite a blowout quarter
Sandisk is the real story on the list today, down 13.5% to $1,150.89 on heavy volume. The quarter itself was huge: fiscal Q1 2027 revenue of $11.03 billion, up 378% year over year and 23% sequentially, non-GAAP EPS of $49.51, GAAP net income of $8.1 billion, data-center revenue of $4.8 billion (up 61% quarter on quarter), and Q2 guidance of $12.2 to $12.6 billion. All of that beat the company's own raised guidance of $10.3 to $10.8 billion and EPS of $44 to $46. Management said roughly 60% of the sequential revenue gain came from higher shipment volumes and 40% from pricing. The stated reason for the selloff is competitor Kioxia: it guided to ¥2 trillion ($12.7 billion) operating profit this quarter against analyst estimates of ¥2.35 trillion, and said NAND average selling prices rose only in the mid-20% range in the September quarter versus 70% the quarter before. That deceleration, plus weak Intel guidance and a broad AI-trade wobble, is what Investing.com cites for the move. Sandisk also announced an 8-for-1 forward split, with split-adjusted trading expected to begin November 20.
Sandisk analyst notes split in both directions
The broker response is mixed rather than uniform. Rosenblatt kept its Buy and left its target at $2,400, Susquehanna cut to $2,720 and Evercore ISI to $2,500, while RBC Capital came down to $1,400 and Wells Fargo all the way to $1,300. Headlines elsewhere frame it as a beat with challenges ahead, and one GuruFocus piece argues the NAND slowdown panic may be overdone. Four TradingView write-ups read in full all take the same starting point, strong earnings against a broken chart: one watches whether $1,100 to $1,150 holds, two set up short entries on a bounce into the $1,150 to $1,400 area with downside targets around $1,025, $1,000 and $905 to $930, and the fourth notes the break below the $1,242 to $1,287 support zone that previously held. These are individual traders' personal setups, not research, and all their levels are pre-split.
OpenWorld down 25% after a dilutive raise
OpenWorld fell 25%. It closed a registered direct offering raising roughly $3.5 million gross, sold to a single institutional investor at-the-market under Nasdaq rules, with Maxim Group as sole placement agent. The deal covered 1,494,084 shares plus pre-funded warrants for 1,023,901 shares, with Series A and Series B warrants each for up to 2,517,985 more shares. Shares were at $0.92, near the $0.91 52-week low, already down 44% over the past week. Officers and directors are locked up for 45 days. Separately, the VerifyMe merger deadline has been extended a third time, to October 31, 2026, with VerifyMe shareholders having approved the share issuance. The matching SEC 8-K on the list is headline-only but covers the same agreement.
Butterfly Network and the rest of the decliners
Butterfly Network is down 14.9%. The only item is a Form 144 filed October 31, and the article carries no detail beyond the filing itself, so there is no stated reason for the move here. Below that, the losses are a cluster of AI-infrastructure and semi names with no company-specific news attached in the list: Datadog down 11.5% (headlines point to the broad tech selloff, plus a Form 4 showing CTO Alexis Le-Quoc selling $12.06 million of class A stock, and option activity), Tower Semiconductor down 11.4% ahead of Q3 earnings, Coherent down 11.3% with Morgan Stanley cutting to $325 and another house to $262, Astera Labs down 10.9%, Nebius down 10.4% with a director buying 148 shares, NetApp down 8.8%, Credo down 8.7%, Arista down 8.3%, Micron down 5.3%, Broadcom down 5.5% (D.A. Davidson upgraded to Buy with a $400 target), TSMC down 5.9%, Oracle down 6.4%, Vertiv down 5.5%, and SpaceX down 6.4%. A DeItaone post on the list tallies peak drawdowns across these names, with Broadcom cited at -31.9% and SpaceX at -31.2% from their 2026 highs.
Small set of gainers and quieter names
Kosmos Energy is up 6.3% ahead of November 2 Q3 results. Stagwell is up 5.2%, with Wells Fargo and B. Riley both raising targets to $12 and an 8-K/A on officer changes. Exelixis is up 4.8% on five target raises the same day, from TD Cowen to $76, Morgan Stanley and Truist to $60, RBC to $58 and Barclays to $54. Accenture is up 4.5%, Comcast 4.3%, Incyte 3.1% on its own cluster of notes including an Oppenheimer upgrade to Outperform at $144. Apple is down just 1.2% and dominates the list by item count, but most of those are unrelated BlackRock and Amundi 13F headlines filed under the ticker; the Apple-specific items are the pre-earnings pieces, the Alibaba Qianwen integration, and Apple retaking the most-valuable-company title from Nvidia. PayPal, Netflix, Adobe and Costco are all effectively flat.
OpenWorld raises $3.5m, stock down a quarter
OpenWorld is down 25% and the reason is on the tape. The company closed a registered direct offering on Friday, roughly $3.5 million gross before fees, sold to a single institutional investor through Maxim Group as sole placement agent on a best-efforts basis. The structure: 1,494,084 common shares plus pre-funded warrants for 1,023,901 shares, with Series A and Series B warrants each covering up to 2,517,985 additional shares. Priced at-the-market under Nasdaq rules, off the Form S-3 shelf that went effective in February 2025. The company and its officers and directors are locked up for 45 days. Investing.com notes the stock was at $0.92 against a 52-week low of $0.91 and down 44% over the prior week, so the raise landed into an already broken price. Context from the same piece: VerifyMe shareholders have approved the merger that would make OpenWorld a wholly owned subsidiary, and the deadline was extended a third time to October 31, 2026. Two SEC 8-K headlines are also in the list, one of which flags Item 3.01, notice of delisting or failure to satisfy a continued listing standard, alongside unregistered sales of equity. That 8-K is headline-only, so the detail behind the listing item isn't in what I've read.
SanDisk down 13.5% on Kioxia NAND warning
SanDisk is the busiest name here, down 13.5% to $1,150.89, and the fall came the day after a very strong quarter. September-quarter revenue was $11.03 billion with adjusted EPS of $49.51, beating its own raised guidance of $10.3–10.8 billion and $44–46. Revenue was up 378% year over year and 23% sequentially, with management attributing about 60% of the sequential gain to volume and 40% to pricing. Data-center revenue rose 61% quarter over quarter to $4.8 billion, GAAP net income was $8.1 billion, Q2 guidance is $12.2–12.6 billion, and the company announced an 8-for-1 forward split with adjusted trading expected to start November 20. The stated trigger for the selloff is Kioxia: it guided to ¥2 trillion ($12.7 billion) operating profit against analyst estimates of ¥2.35 trillion, implying almost flat quarter-on-quarter NAND pricing, and said its average NAND selling price rose in the mid-20% range in the September quarter versus 70% the quarter before. Investing.com also cites weak Intel guidance and general AI-trade nerves. Intel, in the same page's movers table, was down 28.58%.
SanDisk analyst and chart reaction
The sell-side response split. Rosenblatt kept a Buy with the target at $2,400, while Wells Fargo cut to $1,300, RBC Capital to $1,400, Susquehanna to $2,720 and Evercore ISI to $2,500, all maintains with lower targets. Four TradingView posts I read are all watching the same breakdown: the $1,242–$1,287 shelf has been lost and retested from below, and the authors frame $1,100–$1,150 as the immediate test, with $1,025, $1,000 and $905–930 named as the next levels down and $1,300–$1,400 as the line that would invalidate the bearish read. These are individual traders' setups, not research, and several of them are padded with Bitget referral promotion, so weight accordingly. All their levels are pre-split. One GuruFocus headline takes the other side, arguing the NAND slowdown panic may be overdone.
Butterfly Network down 14.9%, no substance behind the item
Butterfly Network is down 14.9%, but the only full-text item on it is an Investing.com stub for a Form 144 filing dated 31 October with no detail beyond the headline itself. Nothing in the material explains the move. If you care about this one, the filing is where to go.
The broader AI and memory complex sold off
Most of the rest of the watchlist moved with the same tape. Datadog fell 11.5%, with GuruFocus tying it to a broad tech selloff on October 30 and separate headlines noting CTO Alexis Le-Quoc sold $12.06 million of class A stock and that the stock carries a maintained Buy ahead of Q3 earnings. Tower Semiconductor dropped 11.4% going into its Q3 report, Coherent 11.3% with Morgan Stanley cutting its target to $325 and another firm trimming to $262, Astera Labs 10.9%, Nebius 10.4% on what GuruFocus attributes to AI cloud expansion concerns, NetApp 8.8%, Credo 8.7%, Arista 8.3%, TD Synnex 7.2%, Taiwan Semi 5.9%, Broadcom 5.5%, Vertiv 5.5% and Micron 5.3%. Oracle lost 6.4%, with headlines on its funding ceiling excluding debt refinancing and a piece framing the bull and bear case as AI backlog against debt burden. The Investing.com market tables on the pages I read put the Nasdaq proxy down 3.46% on the day, the S&P 500 down 1.82%, VIX up 12.91%, and reference a Nasdaq slide of over 5% for the month, its worst since March 2025.
Space, defence and precious metals names lower
SpaceX-linked SPCX fell 6.4% against an unusually loud headline cluster: a Tesla merger facing a China problem and possible Beijing block, Shotwell saying two million shares will be gifted to children's Trump Accounts, a reported reliance on Anthropic for a third of revenue, a malware incident at SpaceX-owned Cursor affecting up to 5,000 users, and two Investing.com pieces simply asking why the stock is sliding. All headline-only, so I can't tell you which of those actually drove it. Rocket Lab was down 7.4%, Red Cat 8.3% alongside four director Form 4 filings, TeraWulf 8.0% with B. Riley cutting its target to $26, AST SpaceMobile 4.9%. On the metals side AngloGold Ashanti fell 6.2% and Wheaton 5.4%, both flagged as entering oversold territory, consistent with gold futures down 3.63% and silver down 6.20% on the day per the quote tables.
The green side of the board
Kosmos Energy rose 6.3% ahead of Q3 results due November 2 before the open. Stagwell gained 5.2% with Wells Fargo, B. Riley and Needham all raising targets to $12.00, plus an 8-K/A on officer departure and compensatory arrangements. Exelixis added 4.8% behind a clean sweep of target raises, TD Cowen to $76, Morgan Stanley and Truist to $60, RBC to $58 and Barclays to $54. Accenture was up 4.5% and Comcast 4.3%. Incyte rose 3.1% with Oppenheimer upgrading to Outperform at $144 and several target raises, though Wells Fargo went the other way to $127. PayPal was flat after a Q3 beat and raised 2026 EPS guidance.
Low-signal items
A large block of the list is GuruFocus 13F-style notes on BlackRock and Amundi position changes in unrelated names, tagged to Apple but with nothing to do with it. Apple itself was down 1.2%, and the headlines there are mostly earnings-preview chatter plus notes that it overtook Nvidia as the most valuable company and that Bank of America lowered its iPhone forecast on a staggered launch. Netflix, Adobe, PayPal and Avery Dennison were essentially unchanged.
OpenWorld down 25% on an 8-K with delisting language
The biggest mover on the list is OpenWorld, off 25%. The full-text item from Investing.com is just a stub announcing the 8-K filing for 30 October with no detail in the body, so there's no explanation there. The companion SEC EDGAR headline does list the filing's items, and they are worth noting: entry into a material definitive agreement, notice of delisting or failure to satisfy a continued listing rule, unregistered sales of equity securities, Reg FD disclosure, and financial statements and exhibits. Nothing in the material explains the terms behind any of those, but the combination of a listing-standard notice and unregistered equity sales is the only concrete thing attached to a quarter-off day. If you hold this, the filing itself is the thing to read.
SanDisk down 13.5% despite a large earnings beat
SanDisk is the most heavily covered name here and fell 13.5%, closing around $1,151.60 on 16 million shares. The earnings were strong: September-quarter revenue of $11.03 billion and adjusted EPS of $49.51, both above the company's own raised guidance of $10.3 to $10.8 billion and $44 to $46. Revenue rose 23% sequentially and 378% year on year, with management attributing about 60% of the sequential gain to volume and 40% to pricing. Non-GAAP gross margin was 85.1% against 84.6% in the prior quarter, data centre revenue rose 61% sequentially to $4.8 billion and is now close to 45% of the total, adjusted free cash flow was $5.7 billion, and there was another $5 billion of buybacks in the quarter. December-quarter guidance is $12.2 to $12.6 billion of revenue and $55 to $57 EPS, with gross margin of 84.5% to 85.5% despite component-cost inflation. The board approved an 8-for-1 stock split distributed 19 November. Non-binding memorandum purchase orders stand at $88.9 billion, down from $91 billion previously, covering half of fiscal 2027 bits and two-thirds of fiscal 2028.
What pushed SanDisk down: Kioxia's NAND pricing signal
The stated trigger for the fall is Kioxia. The Tokyo competitor guided to ¥2 trillion ($12.7 billion) of operating profit this quarter against analyst estimates of ¥2.35 trillion, implying nearly flat quarter-on-quarter price increases, and said its NAND average selling price rose in the mid-20% range in the three months to September versus a 70% rise the quarter before. Investing.com also cites weak Intel guidance and general nerves about the AI trade as contributors. That fits the wider tape in the same articles: Intel was down 28.6%, Nasdaq off 2.86% on the day and heading for its worst month since March 2025, VIX up 13%, with AMD down 10.9%, Qualcomm 11.1%, Dell 10.8% and Micron 5.3%.
The analyst cluster on SanDisk, all cuts, all still constructive
Six separate price-target changes landed, every one of them downward and none of them a downgrade. Mizuho went to $1,900 from $2,050, keeping Outperform, flagging December gross margin guided down roughly 10 basis points to around 85.0% and December revenue of $12.4 billion against $12.5 billion consensus, while valuing the stock at about 8 times fiscal 2027 earnings versus the SOX at roughly 17. Goldman Sachs cut to $2,000 from $2,200 on valuation, keeping Buy, pointing to multiple eSSD wins at hyperscalers and limited NAND supply additions ahead. BofA also went to $2,000, from $2,500, Buy maintained, lowering its target multiple for late-cycle valuation concerns while citing AI inference making NAND more indispensable. Headline-only notes show RBC Capital cutting to $1,400, Susquehanna to $2,720 and Evercore ISI to $2,500. Note the spread there, $1,400 to $2,720, which is unusually wide for the same quarter. Two TradingView posts and a GuruFocus piece titled "Why The Panic Over A NAND Slowdown May Be Overdone" cover the technical and sentiment side; the TradingView items are individual traders' chart setups around the $1,200 level, not research.
Datadog, Coherent, Astera and the rest of the semi and AI-infrastructure complex
Below SanDisk, the losses run along the same line. Datadog fell 11.5% with only headline items, a Rosenblatt reiteration ahead of earnings and a Buy rating maintained, nothing explaining the move. Tower Semiconductor was down 11.4% ahead of Q3 results, Coherent 11.3% with Morgan Stanley cutting to $325 and another firm to $262, Astera Labs 10.9%, Nebius 10.4% (it reports Q3 on 12 November), NetApp 8.8%, Credo 8.7%, Arista 8.3% and TeraWulf 8.0%, where B. Riley trimmed its target to $26. Oracle fell 6.4%, with Investing.com running both a "why is Oracle sliding" piece and one on its AI backlog meeting its debt burden, plus a separate note that Alphabet dropped 12% on capex. Broadcom was off 5.5%, Taiwan Semi 5.9%, Micron 5.3%. None of these were read in full, so treat the attributions as headline-level only.
SpaceX headline cluster
SPCX fell 6.4% with a dense run of headlines and no full text: a Cursor malware incident said to affect up to 5,000 users, a Binance hack story referencing a SpaceX stake, two Investing.com pieces on why Beijing could block the SpaceX-Tesla merger, and one claiming SpaceX relies on Anthropic for a third of its revenue. A separate X post lists SPCX down 31.2% from its June 2026 peak, alongside AVGO at -31.9%, GOOGL -30.4%, MU -26.1% and META -21.5%.
The green side: Stagwell, Exelixis, Incyte, Kosmos
Gains were modest and mostly biotech and small-cap. Kosmos Energy rose 6.3% ahead of 2 November Q3 results. Stagwell was up 5.2% with Wells Fargo, B. Riley and Needham all raising to $12.00 and an 8-K/A on officer departures and appointments. Exelixis gained 4.8% after Q3, with Morgan Stanley, Truist and BMO all going to $60, RBC to $58 and Barclays to $54. Incyte rose 3.1% on an Oppenheimer upgrade to Outperform with a $144 target, raised fiscal 2026 revenue guidance, and target rises from RBC ($117), Barclays ($143) and Evercore ($127), with Wells Fargo cutting to $127 against the grain. Accenture was up 4.5%, mostly on fund-flow and commentary items rather than company news.
Quiet names and noise
Apple was down only 1.2% but carries by far the most items, nearly all of them GuruFocus 13F and ETF-flow summaries about BlackRock and Amundi positions in unrelated companies, which have nothing to do with Apple. The genuine Apple content is headline-level: BofA lowered its iPhone forecast on staggered launch concerns while separately arguing Wall Street may be misreading the stock, UBS reiterated neutral on iPhone wait times, and earnings are imminent. Netflix, PayPal, Adobe, Axsome, Joby and SoundHound all moved less than 3.5% with routine headlines behind them. One macro item is in the list: Q3 employment cost index +0.8% against +0.8% consensus, down from +0.9% in Q2, with wages at +0.7% and benefits +0.9%.
