SMX collapses 47.5%
SMX was down 47.5%, closing at $1.89 after a day's range of $1.70 to $5.61 on volume of 10.3 million shares against a 20-day average of about 256,000. The Yahoo Finance page gives no stated reason for the drop. What it does show is a market cap of just $2.06 million, a 52-week range running from $1.70 up to $5,496, down roughly 99% year to date, with $33.5M total cash and levered free cash flow of -$30.9M. The company's own recent messaging has been about its molecular-marking and traceability platform for gold, silver, plastics and textiles. Shares ticked up 5.3% after hours.
Vicor down 12.9%
Vicor fell 12.9% to $191.50, inside a 52-week range of $57.00 to $382.65. The GuruFocus note attaches no company news to the move; it is a valuation piece, putting GF Value at $72.20 (so 165% above fair value on their method), a GF Score of 81/100 with growth 9/10 but valuation 1/10, a trailing P/E of 61.5x against a five-year median of 74.0x, forward P/E 31.3x, and insider sales of $424.1M over twelve months with no buying.
Nebius hit hardest of the AI infrastructure names
Nebius was down 12.2%, closing at $165.47 on roughly 31 million shares, about 1.7 times its one-month average and its sixth decline in eight sessions after a 10% loss earlier in the week. GuruFocus ties it to broad weakness in the neocloud group, with CoreWeave off nearly 12% the same day. The funding question is the thread running through all four Nebius pieces: Q2 operating cash inflow of $2.246 billion against $5.657 billion of property, equipment and intangibles purchases, a $3.411 billion gap, with $8.042 billion cash plus $1.056 billion restricted at quarter end. The TradingView piece frames the same issue around roughly $8.55 billion of debt and the planned 600 MW Rotterdam data center, noting revenue of $1.36 billion, net margin 3.1%, return on equity 0.4%, and a price-to-sales of 38.1x (GuruFocus puts P/S at 34.12 versus a historical median near 7.0). Dan Ives, via TipRanks on October 15, argued the selloff was a buying opportunity on the grounds that higher rates squeeze financing rather than demand. Against that, insiders have sold $318.2M over twelve months with 33 sells to one buy; the one buy was director Arne Grimme picking up 296 shares on October 16 at $169.99, taking him to 6,181 shares. Earnings are scheduled for October 22.
Aurora Innovation off 10.1%
Aurora fell 10.1% to $4.855 on 35.7 million shares against a 29.2 million average. Yahoo's page flags a five-year US waiver that removed one deployment hurdle for driverless trucks, while pointing to continued cash burn, losses, and a valuation some analysts call stretched. Q2 FY26 revenue was $2M against a $270M loss, trailing cash $1.22B, levered free cash flow -$414M. The average one-year target shown is $12.13, and Oppenheimer on October 8 kept Outperform while raising its target from $15 to $16. Earnings October 28.
Codexis and Xometry
Codexis was down 8.8% to $1.24, with no news attached on the Yahoo page beyond the price data: 52-week range $0.96 to $2.98, Q2 FY26 revenue $14.91M and a $12.01M loss, cash $54.9M, debt/equity 220%. Earnings November 5. Xometry fell 8.7% to $90.91, with a Form 144 filed the same day. The GuruFocus piece on it is valuation only, no operating news: GF Value $48.11 against the $90.91 price, GF Score 71/100 with growth 10/10 and valuation 1/10, forward P/E 70.5x, and net insider selling of $15.9M over twelve months ($4.0M bought, $20.0M sold).
Rocket Lab's Neutron delay, eighth straight down day
Rocket Lab was down 8.0% to $50.84, its eighth consecutive decline after drops of 8% and 7% earlier in the week. The cause is specific: inspections found voids, tiny air pockets between carbon fibre layers, in the forward dome of Neutron's first-stage propellant tank, pushing the debut launch from Q4 2026 into 2027. Peter Beck said "possible success isn't our standard." The defect appeared after a switch to automated fibre placement following an earlier manual-tank qualification failure; engineers have replicated it and changed the process, and an aft dome came through the revised process better. Replacement dome manufacturing and inspection is expected to finish before Q1 2027, with first-stage assembly and hydrostatic and cryogenic testing in that quarter. No new launch date. KeyBanc's Michael Leshock cut his target to $100 from $135 keeping Overweight, modelling one fewer revenue-generating Neutron launch in 2027 and citing lower multiples across high-growth space names; Citizens' Trevor Walsh kept Market Outperform but cut to $90 from $130. ARK bought 168,633 shares, about $9.3 million, on Thursday. Backlog was $2.36 billion at end-June, up 137% year on year, with Q2 free cash flow of -$110 million. Insiders have sold $683.3M over twelve months with no purchases.
TeraWulf
TeraWulf fell 7.4% to $11.68, down 24.1% over the month and 15.7% over the year, in a 52-week range of $10.35 to $29.84. The GuruFocus piece supplies no event behind the drop, only metrics: GF Value $5.94 against the price, GF Score 38/100 with growth 0/10 and financial strength 2/10, forward P/E 174.6x, and net insider selling of $35.6M. Separately, Cantor Fitzgerald kept Overweight and lowered its target to $30, headline only.
The semis and AI-complex backdrop
The common driver behind several of these is visible in the index data on the pages themselves: Nasdaq closed down 2.14%, S&P 500 down 1.09%, VIX up 21.45% to 19.99, with the 10-year at 5.10%. Headline-only items in your list point the same way, including one from Investing.com that the SOX chip index posted its longest losing streak since 2008 as AI worries deepened, and an item noting Anthropic received a BB+ rating from KBRA ahead of a $35 billion chip financing, with banks assembling a further $60 billion. Among your chip and AI names, Micron was down 5.6%, Astera Labs 5.4%, Credo 4.9%, Oracle 4.6%, Arista 4.6%, Broadcom 4.5%, TSMC 2.3%, with Tower Semiconductor off 6.8%. Datadog fell 7.2%. All of these are headline-only, so I can't tell you more than that the moves happened alongside the sector selloff.
Netflix cluster ahead of earnings
Netflix was down 2.9% on a heavy run of headline-only items: Peter Rice, formerly of Disney, named chief content officer, alongside reports of layoffs and a leadership shakeup, with an October 26 handover mentioned. BMO cut its target to $125, Wedbush to $90, Rosenblatt held at $75 with a Neutral rating. Earnings land next week alongside Tesla, Meta, IBM and others.
Smaller decliners and quieter names
UiPath was down 6.3%, Revolution Medicines 6.0% with William Blair initiating at Outperform, Planet Labs 6.7% with director Kristen Robinson selling $565,560 of stock, Beam Therapeutics 5.1% with CEO John Evans selling $1.19M, NioCorp 4.1% on two 8-K filings covering results and a material agreement, Sezzle 3.6%, Modine 3.3%, Generac 2.9%, Mercury Systems 2.8%, Amphenol 2.6%. All headline-only. Apple was the main gainer at up 0.4%, with pre-orders for the foldable iPhone Duo selling out within minutes and delivery dates slipping into January 2027, while UBS kept Neutral at $296 citing iPhone Pro wait times of four days versus longer in prior cycles. Accenture up 2.1%, Aflac 1.6%, Costco 1.1%, Paychex 0.8%. SpaceX fell 1.7% amid a thick but entirely headline-level stream on Starlink in Ukraine, spectrum, and Tesla merger speculation, including Barclays calling a merger feasible with uncertain timing, and Evercore raising its target to $275. Nothing in the rest of the list carries enough behind it to need your attention today.
SMX collapses to $1.89
SMX was the day's extreme, down 47.5% to $1.89 on volume of 10.3 million shares against a 256,000-share 20-day average, roughly 40 times normal. The Yahoo page shows a day's range of $1.70 to $5.61 against a previous close of $3.60, a 52-week range running from $1.70 all the way up to $5,496 (reverse-split distortion), and a market cap now at $2.06 million. It is down 88% over a month and 98.97% year to date. The page gives no reason for the move; the only recent coverage it notes is company-authored material on its Digital Material Passport and molecular-marking work in gold, silver, plastics and luxury goods. Shares were $1.99, up 5.29%, after hours. Note the item headline here says +16.4%, which contradicts the quote and the article itself.
Vicor down 12.9%
Vicor fell 12.9% to $191.50. GuruFocus gives no news catalyst, just its valuation read: GF Value of $72.20 against the current price, which it calls 165% overvalued, a GF Score of 81/100 with growth at 9/10 and valuation at 1/10, trailing P/E of 61.5x versus a five-year median of 74x, and forward P/E of 31.3x. It also flags $424.1 million of insider selling over twelve months with no buying, and seven gurus holding with two adding and six trimming. The 52-week range is $57.00 to $382.65.
Nebius down 12.2%, funding model under scrutiny
Nebius fell 11.99% to $165.47, losing $22.94 on about 31 million shares, roughly 1.7 times the one-month average, its sixth decline in eight sessions and following a 10% drop earlier in the week. GuruFocus ties it to a broad neocloud selloff, noting CoreWeave fell nearly 12% in the same session. The substance behind the worry is cash: second-quarter operating cash inflow was $2.246 billion while purchases of property, equipment and intangibles took $5.657 billion, a $3.411 billion gap, against quarter-end cash of $8.042 billion plus $1.056 billion restricted. A TradingView piece frames the same issue around the planned 600 MW Rotterdam data center and roughly $8.55 billion of debt, with revenue of $1.36 billion, net margin of 3.1% and return on equity of 0.4%, and asks whether higher financing costs break the economics of debt-funded buildout. Valuation is stretched on P/S at 34.12 versus a historical median near 7.0 (the TradingView piece cites 38.1x), EPS is negative at -$0.13, and GF Score is 52/100 with momentum 10/10 and valuation 2/10. Against that, Dan Ives was reported by TipRanks on October 15 calling the neocloud selloff a buying opportunity on the argument that rates squeeze financing, not demand. Insiders sold $318.2 million over twelve months with no buys, though director Arne Grimme filed a Form 4 for a purchase of 296 shares at $169.99, taking him to 6,181 shares, the single insider buy against 33 sells in a year. Earnings are scheduled for October 22.
Aurora down 10.1% into October 28 earnings
Aurora Innovation fell 10.09% to $4.855 on 35.7 million shares against a 29.2 million average, which puts it down 16.7% on the week and 23.7% over a month, though still up 26.4% year to date. The Yahoo page offers no specific catalyst, describing the company as a scale-up story targeting more than 30,000 driverless trucks and about $5 billion of revenue by 2030 while still burning cash. Q2 FY26 revenue was $2 million against a $270 million loss, cash is $1.22 billion, levered free cash flow is -$414 million. Earnings are October 28. The average one-year target shown is $12.13; Oppenheimer maintained Outperform on October 8 and raised its target from $15 to $16.
Rocket Lab down 8% on Neutron slipping to 2027
Rocket Lab fell nearly 8% to $50.84, an eighth straight down day after drops of 8% and 7%, and is down about 13% on the week. The cause is specific: inspections found voids, tiny air pockets between carbon-fiber layers, in the forward dome of Neutron's first-stage propellant tank, produced via an automated fiber-placement process adopted after an earlier qualification failure on a manually built tank. Peter Beck said "possible success isn't our standard" and chose to redesign rather than fly. Engineers have replicated the defect and changed the process, and an aft dome passed with better results. Replacement dome manufacture and inspection should finish before Q1 2027, with first-stage assembly and hydrostatic and cryogenic testing in that quarter; no new launch date was given. Analysts cut targets but held ratings: KeyBanc's Michael Leshock to $100 from $135, stripping out one revenue-generating 2027 Neutron launch and citing lower multiples across high-growth space names, and Citizens' Trevor Walsh to $90 from $130 at Market Outperform. Cathie Wood's ARK bought 168,633 shares worth about $9.3 million on Thursday as the stock fell nearly 7%. Offsetting the delay, backlog was $2.36 billion at the end of June, up 137% year on year, plus an agreement covering 20 Electron launches; Q2 free cash flow was -$110 million. GuruFocus puts GF Value at $39.19, GF Score at 77/100 with growth 10/10 and profitability 3/10, P/S at 38.78 versus an 18.88 median, and insider selling at $683.3 million over twelve months with no buys. A TradingView post argues the pullback has reached the 61.8%–78.6% Fibonacci zone on long-term trendline support with oversold momentum.
Codexis and Xometry
Codexis fell 8.82% to $1.24 on below-average volume, 980,000 shares against a 1.14 million average, with no catalyst on the page. It is down 51% over six months and 53% over a year, with a 52-week low of $0.96. Q2 FY26 revenue was $14.91 million on a $12.01 million loss, cash $54.9 million, debt-to-equity 220%. Earnings are November 5; Piper Sandler kept Overweight on August 17 while cutting its target from $9 to $8. Xometry fell 8.7% to $90.91, again with no news attached, only GuruFocus's valuation note: GF Value $48.11 against the price, GF Score 71/100 with growth 10/10 and valuation 1/10, forward P/E of 70.5x, and net insider selling of $15.9 million over twelve months ($4.0 million bought, $20.0 million sold).
TeraWulf down 7.4%
TeraWulf closed down 7.5% at $11.68, off 24.1% over a month and 15.7% over a year, against a 52-week range of $10.35 to $29.84. No news driver is given; GuruFocus has GF Value at $5.94, GF Score at 38/100 with growth 0/10 and financial strength 2/10, a forward P/E of 174.6x, and net insider selling of $35.6 million. Separately, and headline-only, Cantor Fitzgerald kept Overweight while lowering its target to $30.
The AI and semi complex, headline-only
The common thread under most of the rest is the same risk-off tape the Nebius and Rocket Lab pieces describe. The Nasdaq closed down 2.14% at 26,140, the S&P 500 down 1.09%, and VIX up 21.45% to 19.99, with a headline on the Investing.com page noting the SOX chip index posted its longest losing streak since 2008 on AI worries. On the watchlist: Datadog down 7.2%, Tower Semiconductor down 6.8%, UiPath down 6.3%, Micron down 5.6% with a GuruFocus headline attributing it to the Nasdaq tech selloff, Astera Labs down 5.4% with Stifel reiterating a $460 target, Credo down 4.9%, Oracle down 4.6%, Arista down 4.6%, and Broadcom down 4.5%, with one headline flagging a signal in AI chip stocks not seen since 2015 and another noting Anthropic received a BB+ rating from KBRA ahead of a $35 billion chip financing deal, with roughly $60 billion more being assembled. TSMC fell 2.3% despite record Q3 results, a Barclays target raise to $670, and headlines on a planned $4 billion Taiwanese AI hub in Texas serving Nvidia's supply chain. These are all headline-only, so the moves are what I can state, not the reasoning behind each.
Netflix, Apple, SpaceX
Netflix fell 2.9% on a leadership story: Peter Rice, formerly of Disney, was named Chief Content Officer, alongside reported layoffs. Rosenblatt held Neutral at $75, BMO lowered to $125 and Wedbush to $90. Netflix reports next week alongside Tesla, Meta and others. Apple was one of the few green names, up 0.4%, with headlines on the iPhone Duo foldable selling out within minutes of pre-orders opening and delivery slipping toward January 2027, UBS reiterating Neutral at $296 on softer Pro wait times, and the UK CMA proposing changes to tap-to-pay access. SpaceX fell 1.7% despite Evercore raising its target to $275, with a cluster of items on Tesla merger speculation (Barclays calling it feasible but uncertain on timing, prediction markets at 77% odds by 2028) and the Starlink Ukraine access question. All headline-only.
Everything else quiet
The remainder of the list is routine, mostly Form 4 filings and small moves: Planet Labs down 6.7% with director Kristen Robinson selling $565,560 of stock, Revolution Medicines down 6.0% with William Blair initiating at Outperform, Beam down 5.1% with CEO John Evans selling $1.19 million, plus sub-4% moves in NioCorp, Sezzle, SoundHound, Modine, Netflix peers and the usual ETF flow notes. Nothing there needs a closer look on its own.
SMX collapses with no stated reason
SMX (Security Matters) is down 48.6%, the worst move on the list by a wide margin. The alert line that generated the item described a 16.4% gain on volume 6.5 times the 20-day average, but the Yahoo quote page behind it shows the stock closing at $1.89, down $1.71 or 47.5%, with a day's range of $1.70 to $5.61 and volume of 10.1 million against an average of 93,576. That is the whole of the material, a quote page, with no news attached explaining the move. Context from the same page: market cap is $2.06m, the stock is down 88% over one month and roughly 99% year to date, the 52-week range runs from $1.70 to $5,496, and the company carries $33.5m cash against levered free cash flow of -$30.9m. If you hold this, the page itself offers no cause.
Nebius down 12.2% on funding-gap worries
Nebius fell 12.2%. GuruFocus framed it as a cash question rather than a demand question: in the second quarter Nebius generated $2.246bn of operating cash inflow while spending $5.657bn on property, equipment and intangibles, a $3.411bn gap. Quarter-end cash and equivalents were $8.042bn with a further $1.056bn restricted. The piece noted Dan Ives had argued on October 15 via TipRanks that the neocloud selloff was a buying opportunity because higher rates squeeze financing rather than underlying demand, and the article's point was that the buildout still has to be paid for. GuruFocus puts its GF Score at 52/100 with momentum well ahead of the other categories. Separately, a Form 144 filing for Nebius Group dated 15 October appeared, headline only with no detail in the item.
Codexis off 9.2%, no news behind it
Codexis is down 9.2%, trading around $1.245 intraday on volume of 975k against a 1.14m average, so a large move on unremarkable volume. The item is a quote page with no accompanying story, so there's no stated cause. For reference from that page: Q2 FY26 revenue of $14.91m and a $12.01m loss, $54.92m cash, next earnings November 5, and Piper Sandler maintaining Overweight back on 17 August while cutting its target from $9 to $8.
AST SpaceMobile down 8.6% after a day-earlier gain
ASTS fell 8.6% today. The article covering it is dated the prior session and describes a 5.5% rise to $44.46 on October 15, so it doesn't address today's drop. What it does give: a 52-week range of $39.87 to $133.86, a GF Score of 44/100 with profitability at 1/10 and growth 0/10, and insider activity of $0.8m bought against $451.6m sold over the past twelve months, a net $450.8m of selling. GuruFocus's own GF Value of $582.48 against the $44.46 price is flagged in the article as unreliable for a loss-making, cash-flow-negative company.
Rocket Lab down 8.0% on the Neutron delay
This is the most heavily covered name in the list, with eight separate items, and they all trace to one event. On October 14 CEO Peter Beck said the first Neutron launch slips into 2027 from Q4 2026. The cause is manufacturing defects in the forward dome of the first stage's carbon-composite propellant tank: inspections found small air pockets, or voids, between carbon fibre layers, traced to a recent design change that thickened parts of the tank for strength and made those sections harder to cure without trapping air. Beck said the voids would not necessarily cause a failure but the tank missed the company's safety margins, hence "Possible success isn't our standard." Rocket Lab says the manufacturing process has been fixed and validated on a second tank section, with replacement dome manufacture and inspection finishing before Q1 2027 and first-stage assembly plus hydrostatic and cryogenic testing during that quarter. Needham's read is a minimum four-month delay, with key tests possibly as early as January and no launch before Q2 2027.
The analyst response to Rocket Lab splits on targets, not ratings
Every firm covered kept its rating and only moved numbers. Citizens' Trevor Walsh held Market Outperform and cut to $90 from $130. KeyBanc's Michael Leshock held Overweight and cut to $100 from $135, citing one fewer revenue-generating Neutron launch in 2027 plus lower multiples across high-growth space stocks. Needham kept Buy and $120 while trimming its FY2027 revenue estimate. Stifel reiterated Buy at $132 and Cantor Fitzgerald Overweight at $122. Against that, ARK Invest bought 168,633 shares worth about $9.3m on Thursday as the stock fell nearly 7%. Other figures across the pieces: the stock is down roughly 19% on the week and about 21% year to date, versus the S&P Aerospace & Defense ETF down about 7.6% and the Russell 3000 up about 12%; backlog was $2.36bn at end-June, up 137% year on year, with an agreement covering 20 Electron launches; Q2 free cash flow was negative $110m; insiders sold about $26.96m over three months and $683.3m over twelve, with no buying. GuruFocus scores it 77/100 and calls it roughly 41% overvalued against a GF Value near $39 at a $55.25 price. One further headline-only item, "Company News for Oct 16, 2026" from Nasdaq, is tagged to RKLB with no detail given.
TeraWulf down 7.4% as Cantor trims target
WULF fell 7.4%. Cantor Fitzgerald kept its Overweight rating on October 12 but cut the target to $30 from $37. GuruFocus is considerably more negative on the name than the rating implies: GF Score of 38/100, financial strength 2/10, profitability 2/10, valuation 1/10, momentum 7/10, and a GF Value of $5.94 against a $12.62 price. Insiders bought $189,949 and sold $5,321,200 over the last three months. Market cap about $6.3bn.
Butterfly Network and other filing-only items
Butterfly Network is down 7.8%, and the only item attached is a Form 4 for director Michael Noonen dated 13 October, with no transaction detail in the material. Nothing in the list explains the move. Planet Labs is down 6.7% with a Form 144 filing headline and an unrelated Truth Social post about a Texas Senate race; UiPath is down 6.3% with a Form 144 and a chart alert noting the move came on half the usual volume. None of these carry an explanation.
The broad AI and semis selldown
Several of your names moved together with the tape rather than on their own news. The Nasdaq closed down 2.14% and the VIX rose 23.7% to 20.38, with Investing.com's front page running headlines on the Nasdaq's worst week in over 18 months, Barclays' Cau saying the best of the AI trade may be over, and BofA advising a risk-off stance on higher real yields. Within that, Datadog fell 7.2%, Coherent 7.1%, Micron 5.6%, Astera Labs 5.4%, NetApp 5.1%, Arista 4.6%, Oracle 4.6%, Broadcom 4.5% and TSMC 2.3%. The Micron items are headline-only and mostly routine: an "ETFs are net sellers" note, a cluster of Form 4s dated 13 October covering essentially the whole board and executive team, and a report that SVP and Chief Legal Officer Michael Ray sold $5.8m of stock. Investing.com ran a "Why is Micron stock sliding today?" piece, headline only, so I can't tell you what it says. Oracle has headline-only items on moderately bearish options sentiment and $66.8m of net ETF buying on October 14, and Broadcom items on $121.5m of net ETF buying plus a note that Anthropic received a BB+ rating from KBRA ahead of a $35bn chip financing deal with another $60bn reportedly being assembled. TSMC headlines reference a raised $670 target from an unnamed firm, DA Davidson holding at $500, Q3 earnings call highlights, and a planned $4bn Taiwanese AI hub in Texas tied to Nvidia's supply chain.
Netflix down 2.9% on a content-chief change
Netflix is the busiest headline-only cluster. Peter Rice, formerly of Disney, was named Chief Content Officer, with Bela Bajaria departing, and multiple outlets tie the share dip to that announcement alongside a workforce reduction. BMO cut its target to $125 citing engagement concerns, Wedbush cut to $90, and Rosenblatt held at $75 with a Neutral rating. Earnings are flagged as upcoming in IBD's calendar pieces. These are all headlines, so I don't have the reasoning behind the target cuts beyond BMO's stated engagement concern.
SpaceX down 1.7% amid heavy but mostly headline-level flow
SPCX fell 1.7% on a long run of headlines: prediction markets putting Tesla-SpaceX merger odds at 77% by 2028, Barclays calling a merger feasible with timing and approval uncertain, Evercore ISI raising its target to $275 on compute growth, Tesla unveiling a Roadster using SpaceX thrusters, and a Reuters-sourced report that the White House ordered SpaceX to limit Ukraine satellite service, with Trump saying neither he nor Musk was responsible and Zelenskiy saying there is no discussion of substituting Starlink. European satellite names including Eutelsat rallied on those Starlink headlines. Earnings are due.
Biotech and the smaller names
Revolution Medicines fell 5.9% with William Blair initiating at Outperform, Beam fell 5.0% with only a Form 144 attached, and CRISPR fell 4.3% with two Form 4s and a UBS initiation at Neutral with a $52 target. All headline-only, so no reasoning available on any of them.
Apple the exception on the upside
Apple rose 0.4%, one of the few green names and covered as a defensive hold with AI stocks under pressure. The foldable iPhone Duo, at $1,999, sold out within minutes of preorders opening, with delivery slipping from October 23 to November 16-23, though one item notes the fast sellout may reflect limited initial inventory. UBS reiterated Neutral with a $296 target, pointing to Evidence Lab data across 30-plus markets showing iPhone Pro wait times four days shorter than last year. The UK CMA has proposed changes to Apple's tap-to-pay access, which Apple is preparing to contest. There's also a thick layer of routine ETF flow items, including $365.1m of net ETF buying on October 14, and a Form 4 showing SVP Jennifer Newstead sold 2,399 shares for $827,655.
Quiet remainder
The rest of the list is routine. Aflac up 1.6% and AngloGold up 1.4% with only a Japan Post Form 4 and a GF Score piece behind them, Costco up 1.1% on ETF-flow and options-activity headlines, and small declines in SNX, KGS, ONON, CMP, LU, RGNX, TTWO and INCY tied to filings, routine analyst reiterations or fund-flow notes. Nothing there needs a second look today.
Datavault AI jumps on two 8-K filings
Datavault AI is up 12.3%, the largest move on the list. Two 8-K filings landed the same day: one covering officer and director changes plus compensatory arrangements and a Regulation FD disclosure, the other reporting entry into a material definitive agreement. Both are headline-only here, so the substance of the agreement and who is coming or going isn't visible from what I have. The third DVLT item is a TradingView chart post from a retail author calling for a move above $0.40 to $1.00 off a wave pattern, not company news.
Vicor and the AI infrastructure financing selloff
Vicor is down 10.4%, and GuruFocus ties the drop to worries about the cost of financing AI infrastructure buildout. Recent government reports showed hotter-than-expected consumer and wholesale inflation, raising fears that rates stay high enough to squeeze capital-intensive data centre projects. Vicor makes modular power components for data centres, telecoms, aerospace and EVs, with a $10.08bn market cap. GuruFocus puts the stock at $218.67 against a GF Value of $72.10, a 203% premium, a trailing P/E of 70.2x versus a five-year median of 74.21x, and a GF Score of 81 with valuation scored 1 out of 10. Insiders sold $424.1m over the past year with no buying, and six of seven tracked gurus trimmed. The same article names Vertiv and nVent as falling alongside it, and Vertiv does appear separately on your list down 3.6%, with Mizuho cutting its target to $280 and GuruFocus flagging a GF Value of $179.56 against a $214.75 price. Arista is down 5.0% and Coherent 4.8%, both headline-only, and the TSMC and Micron items include a GuruFocus piece headlined on chip stocks falling on inflation concerns and an Investor's Business Daily headline on chips tumbling on AI investment worries. That's the connective thread running through much of today's red.
TeraWulf up on the AI data centre story
TeraWulf is up 9.4%. The only item is a TradingView long write-up, not company news, but it lays out the contracted position: a 20-year Anthropic lease for roughly 401 MW at the Justified Data Campus worth about $19bn over the initial term, multiple Fluidstack deals backstopped by Google credit and warrants, total contracted revenue above $27bn across roughly 839 MW, and projected run-rate rent near $1.76bn at full delivery. Muskie contracted power doubled to 1 GW with the second 500 MW phase moved to 2029, and the Kentucky PSC approved power for Justified. The author cites consensus targets in the $32–33 range against recent levels near $11–13 and references notes from TD Cowen, Wells Fargo and UBS. Treat the framing as a promotional post.
Rocket Lab down on the Neutron delay, with targets split
Rocket Lab is down 6.6% and this is the most heavily covered name on your list. On October 14 CEO Peter Beck said Neutron's first flight slips to 2027. An inspection found air pockets, or voids, in the forward dome of the first-stage carbon-composite propellant tank, traced to a recent design change that thickened sections for strength and made them harder to cure without trapping air. Beck said the bubbles wouldn't necessarily cause a failure but the tank missed internal safety margins: "Possible success isn't our standard." The manufacturing process has been fixed and validated on a second tank section, and the affected part is being rebuilt. The minimum hit is four months of qualification test and assembly; if key tests pass as early as January, a new date gets set, not before Q2 2027. Beck also said second and third rockets are already in production with upgrades pulled forward. Analysts split on magnitude, not direction: Needham held Buy and $120 while cutting its FY2027 revenue estimate on fewer Neutron flights; Citizens cut to $90 from $130, keeping Market Outperform, with Trevor Walsh noting the stock is down about 21% year-to-date against the aerospace and defence ETF down 7.6% and the Russell 3000 up 12%; KeyBanc cut to $100 from $135, Overweight; Stifel reiterated Buy at $132; Cantor Fitzgerald held Overweight at $122, with Andres Sheppard modelling a Q2 2027 debut and the first revenue-generating launch in Q4 2027. GuruFocus has the stock at $55.25 against a GF Value of $39.14, a GF Score of 77 with growth 10 of 10 and profitability 3 of 10, revenue up 53% year over year, and insider selling of $683.3m over twelve months with no buys. One headline-only item flags notable Thursday option activity in RKLB alongside OLLI and MCD.
Intuit, AST SpaceMobile and Nurix valuation notes
Intuit rose 6.4% to $330.17, but it is down 49.5% year-to-date and 48.7% over twelve months. GuruFocus puts GF Value at $831.99, a GF Score of 82 with profitability and growth both 10 of 10 and valuation and momentum both 2 of 10, a trailing P/E of 20.0x against a five-year median of 58.5x, and forward P/E of 13.9x. Insiders sold a net $357.2m over the past year. AST SpaceMobile is up 5.5% to $44.46 against a 52-week range of $39.87 to $133.86; GuruFocus shows a GF Score of just 44, growth 0 of 10 and profitability 1 of 10, with net insider selling of $450.8m. No company news behind either move in what I have. Nurix is up 5.4%: HC Wainwright kept Buy and raised its target to $36 from $34, with GuruFocus noting GF Value of $54.06 against $24.95 and a GF Score of 65. Separately, CSO Gwenn Hansen sold 1,452 shares at $25.00, total $36,300, under a 10b5-1 plan, having exercised options at $1.86; she still directly owns 117,227 shares. That article also recaps post-Q3 target moves from Stifel to $41 on the Roche collaboration, Morgan Stanley to $38, RBC to $35 and Truist to $33.
Adobe and the Nvidia expansion
Adobe is up 4.6% across several headline-only items saying it expanded its Nvidia partnership to speed up creative tools and agentic creation, with Brand Concierge using Nvidia Nemotron due for enterprise customers later this year. A separate GuruFocus headline asks whether it's too late after the rally, saying GF Value reads undervalued. Accenture is also up 4.6% on a GuruFocus valuation headline citing GF Value of $349.90 against $224.92.
Netflix content chief change
Netflix is up 2.9% with a dense headline-only cluster: Peter Rice, formerly of Disney, named chief content officer as Bajaria departs, alongside reported layoffs. Several of those headlines describe shares dipping or sliding, which sits against today's quoted gain. Rosenblatt stayed Neutral, BMO cut its target citing engagement concerns, and Jefferies assumed coverage with Buy at $85. Another headline notes heavy options activity ahead of earnings.
SpaceX headlines, stock lower
SPCX is down 2.3% despite the heaviest headline flow of any name. Tesla unveiled a redesigned Roadster at a SpaceX facility with SpaceX thrusters and a claimed 0.81-second 0-60. Evercore ISI raised its SPCX target to $275 on compute growth. On the geopolitics, Reuters reported the White House ordered SpaceX to limit Ukraine satellite service, a US official later clarified there are no Trump restrictions on Starshield for Ukraine, and Zelenskiy said there's no discussion of substituting Starlink; European satellite stocks extended a rally on the Starlink curb story. The EU plans to fast-track antitrust approval of a SpaceX rival. Musk also posted about a Star Mind computer co-engineered with Nvidia reaching volume production next year. All headline-only.
Semis, Micron insider filings and TSMC
Micron is up 1.9% on a very large batch of Form 4s dated 13 and 14 October covering CEO Sanjay Mehrotra, CFO Mark Murphy, COO Manish Bhatia and most of the board, plus chief legal officer Michael Ray selling $5.8m of stock. These are headline-only filings, so I can't say what's routine vesting versus discretionary. TSMC is down 1.8% after reporting a record quarter, with headlines describing a sell-off anyway and the CEO saying the gap between demand and supply remains large. Taiwan is reported to be planning a $4bn Texas hub for Nvidia's AI supply chain. Broadcom is down 0.6% on ETF-flow and chart headlines, plus a note that Anthropic secured a BB+ rating from KBRA ahead of a $35bn chip financing deal with another $60bn reportedly being assembled.
Everything else is quiet
The rest is low-signal: Take-Two up 4.0% on GTA VI optimism headlines and a Form 144, UiPath up 5.0% and Red Cat, Beam, Planet Labs and Nebius each with only a Form 144, Comcast up 3.4% and NetApp down 3.4% on GuruFocus valuation screens, TD Synnex down 3.3% with chair Dennis Polk selling $629k, AngloGold up 3.1%, Oracle up 3.0% on ETF buying and valuation headlines, Paychex up 2.2% declaring a $1.19 quarterly dividend, CRISPR up 2.6% with UBS initiating at Neutral and a $52 target, and a long tail of Apple ETF-flow items around the $5trn market cap with Apple itself down 0.3%. Datadog is down 1.1% even as Mizuho raised its target to $330. Nothing there needs a closer look on today's tape.
Datavault AI leads the board on a chart post
DVLT is up 12.2%, and the only item behind it is a TradingView chart post from GNRI_Maker, not news. The author argues DVLT finished a correction at $0.1200 and is in a final ending-diagonal wave with a false breakout, naming $0.4000 to $1.00 as where the stock is free to move. That's one trader's technical read with TradingView's own disclaimer attached, and there's no company announcement in the material to go with the move.
Surf Air signs fifth OperatorOS customer
SRFM is up 10.9% after announcing a definitive agreement with Flying Zebra for its OperatorOS flight operations software, the fifth commercial contract for the platform and enough to meet its stated goal of five operators live by end-2026. Surf Air earns a percentage of revenue on every Flying Zebra trip run through the software; Flying Zebra operates four aircraft. The platform is powered by Palantir, handles aircraft and crew scheduling, flight management and reporting for Part 135 operators, has run Surf Air's own Southern Airways and Mokulele since 2025, and was recently approved by the FAA as an authorized system of record for electronic signatures and recordkeeping. Barrett Brown, president of SurfOS, said getting each signed operator actually onto the platform is the priority. GuruFocus covered the same release with the balance-sheet side: market cap $111 million, P/S around 0.75x against a historical median of 0.5x, no meaningful P/E because the company is still lossmaking and cash-flow negative, GF Score 47/100 with growth at 9/10 but financial strength at 2/10, GF Value of $0.65 versus a $0.83 price, and roughly $0.2 million of insider selling over twelve months with no buys.
Morgan Stanley overweight on TeraWulf
WULF is up 9.2%. Morgan Stanley started it Overweight with a $65 target, which it frames as 392% upside, arguing the recent share price decline is disconnected from contract value. The catalysts cited are a credit backstop tied to the Hawesville project, lease agreements for the Muskie site, cash-generating existing assets and European expansion. GuruFocus's counterweight in the same piece: P/S of 28.2x against a 12.7x median, GF Score 38/100, financial strength and profitability both 2/10, debt-to-equity of 35.56, an Altman Z-Score of -0.8, TTM EPS of -4.4, and insiders selling $36.1 million against $0.4 million of buys over the past year.
Upstart rises despite a target cut
UPST is up 8.7% on a day when the only item is a negative one. Citizens kept its Market Underperform rating and cut the target from $20 to $18. GuruFocus notes the stock at $22.51 against a GF Value of $61.72, a GF Score of 66/100 with growth at 8/10 and valuation at 2/10, P/E of 41x versus a five-year median of 65.25x, and insider activity of $1.28 million of buys against $4.37 million of sales over three months. Worth noting the article dates the Citizens action to October 13, 2023, which looks like a stale date stamp in the piece rather than something I can resolve.
SoundHound at a 52-week low
SOUN shows up 7.9% on the quote, but the article covering it is about the stock touching a new 52-week low of $4.46, trading at $4.45 with a $2.01 billion market cap, 80% below its $22.17 high and down 78.18% over a year. InvestingPro puts Fair Value at $5.04 and flags RSI in oversold territory. The piece also recaps Q2 2026: record revenue of $61.9 million, up 45% year over year and 40% sequentially, with an adjusted loss of $0.02 per share against the $0.12 loss analysts expected. Yorkville Ives started coverage In Line with a $6.50 target. The article doesn't explain today's bounce, so take the low as the reported event and the move as the quote.
Aurora Mobile's GPTBots into Japan
The item tagged AUR, up 6.9%, is actually about Aurora Mobile (NASDAQ: JG), whose GPTBots.ai platform has partnered with Tokyo-listed AI Storm to deploy AI tools in the contact centres of its wholly owned subsidiary Nihon Telesystem. NTS has run contact centres for over 38 years and will use GPTBots to digitise veteran agent knowledge across three stages: AI role-play simulations for training, surfacing information during live calls, and automatic post-call summaries. The framing is "Human-Led AI", support rather than replacement, aimed at Japan's contact-centre labour shortage. The article's own ticker box shows JG down 8.35%, so the quote on your line and the stock in the story don't obviously match.
Rocket Lab's Neutron slips to 2027
RKLB is down 6.7%, and this is the busiest story in the list. An October 14 8-K pushed Neutron's first flight into 2027 with no quarter named. The cause is a manufacturing quality problem: voids, small air pockets between carbon-fibre layers, found in the forward propellant dome of the first-stage tank. An earlier tank failed qualification testing in January, which pushed Rocket Lab to automated fibre placement, and the voids then showed up in thicker sections of the forward dome during curing. Peter Beck says the revised process has already produced a good aft dome. A replacement forward dome is in production, with curing, inspection, first-stage assembly, hydrostatic and cryogenic testing all expected to complete in Q1 2027, after which the company will set a launch date. Beck says the second and third rockets are already in production with upgrades pulled forward. Neutron is designed for up to 13,000 kg to low Earth orbit and is the vehicle meant to take Rocket Lab beyond small-satellite launch.
Analysts split on how much the delay matters
The sell side largely stayed positive while trimming. Stifel reiterated Buy with a $132 target, calling it a manufacturing refinement issue from scaling some of the largest carbon composite structures ever built for a launch vehicle, not a fundamental Neutron problem, and noting demand remains strong, more cash than debt on the balance sheet, and 53% revenue growth over the last twelve months. KeyBanc kept Overweight but cut from $135 to $100. TD Cowen's Gautam Khanna reiterated Buy at $90 on October 9. Cantor's Andres Sheppard held Overweight at $122 and now models a Q2 2027 debut with the first revenue-generating launch in Q4 2027, his estimate rather than a company commitment. Raymond James has Outperform at $80, Berenberg Buy at $83. The Investing.com round-up adds the detail that the CFO had tied positive adjusted EBITDA to a successful Neutron test flight and sold about $9.9 million of stock under a pre-arranged plan in early October, that this is the fourth schedule slip (2024 to 2025 to late 2026 to 2027), and that insiders sold roughly $26.96 million over three months. Shares closed $59.18 on Oct 14, down 13% on the week; GF Value sits at $39.14. Forward consensus in that piece: FY2026 revenue $959.7 million, FY2027 $1.39 billion, with the next report tentatively Nov 16. Headline-only items also flag notable RKLB option activity and Cantor's reiteration.
Intuit, Adobe, Accenture gain on headline-only items
Intuit is up 6.3%, with headlines noting the shares rising amid a mixed market, an acquisition of Sequence for AI revenue management tools, and a GuruFocus valuation piece. Adobe is up 4.6% on an expanded Nvidia partnership, with the Deltaone post saying Brand Concierge with Nvidia Nemotron will be available to enterprise customers later this year. Accenture is also up 4.6%, carrying a cluster of analyst notes: TD Cowen raised to $201, Susquehanna to $230, and Stifel reiterated on an AI growth outlook. These are headline-only, so that's all the detail available.
The other notable decliners
Cognition Therapeutics is down 5.7% alongside an H.C. Wainwright reiteration on a patent grant. OpenWorld is down 5.2% with a term sheet for a $1 billion tokenized AI financing programme and a matching 8-K. Coherent is down 5.1% with a B. Riley target cut to $297. Arista is down 5.0% and appears in market-cap-mover lists with Lam Research. Vertiv is down 3.5% after Mizuho cut to $280. All headline-only.
AI credit stress and the chip tape
A connected thread runs through several of your names today, all headline-only. Oracle is up 3.1% but the headlines around it are about credit: default insurance on its debt at a record, credit default swaps widening across US tech, and FTC subpoenas to Anthropic and OpenAI pushing Oracle credit risk higher. The same driver shows in CoreWeave and Nebius headlines, with Nebius up 1.3% and Dan Ives quoted calling the selloff a buying opportunity. On the semis side, TSMC is down 1.8% despite record Q3 profit, up 69%, and 41.1% revenue growth with a strong Q4 outlook; headlines attribute the stock fall to CFO comments on margin pressure and a broader chip selloff tied to inflation data and rising yields. Needham raised TSM to $560. Micron is up 1.9% with headlines on a chip-sector selloff, Chinese competition and a Taiwan bonus dispute. Apple is down 0.3% on a very long but low-substance list, mostly ETF flow notes, plus headlines that it closed above a $5 trillion market cap and is working with Meta to run the Muse AI model on Macs.
Quieter names
The rest of the list is thin. PayPal is up 1.9% despite BofA resuming coverage at underperform and a Glance agentic commerce partnership. Netflix is up 2.9% ahead of earnings with Jefferies at Buy and an $85 target. Take-Two is up 4.0% on GTA VI headlines, Comcast up 3.4% ahead of its Oct 22 report, Paychex up 2.2% with a $1.19 quarterly dividend. Broadcom, Costco, Credo, Datadog, Teva, Beam and the various ETF-flow entries carry no real movement or substance today.
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.
