SK Hynix's U.S.-listed ADR (SKHY) fell roughly -5.5% during Thursday's regular session, extending Wednesday's -2.36% decline. Primary catalyst: Samsung's preliminary Q3 results missed estimates — record 107.4 trillion won operating profit, but revenue and profit came in below consensus.

AAOI fell -13.52% to $105.97 during the regular session, from a prior close of $122.54. The drop led a broader selloff in optical-communications names (Coherent, Lumentum, Credo, Corning) as investors took profits after a roughly +221% year-to-date run.

CBRS is trading down -4.03% to roughly $168 during regular market hours, after closing at $175.05 in the prior session. The decline came amid a broad selloff in AI cloud-infrastructure names, as a BlackRock note warned hyperscalers are burning cash and leaning heavily on debt markets to fund AI buildouts.

TSM is trading down -3.34% to about $456.45 in regular hours, after closing at $472.20 in the prior session. The drop came despite record Q3 revenue of NT$1.49 trillion (+50% YoY) and September sales up +54.6% YoY, both beating estimates.

NBIS fell -7.65% to $219.00, versus a prior close of $237.15, with the decline occurring during regular market hours. The move was part of a broader sell-off in debt-financed AI infrastructure names, with CoreWeave, IREN, and Oracle also trading sharply lower.

ALAB is down -9.36% intraday to roughly $346.49, a sharp reversal from its prior close of $382.25 during regular market hours. The decline occurred during the regular trading session, not premarket or after-hours.

MRVL traded down -4.09% during regular-session hours, falling from a prior close of $284.68 to roughly $273.05. The decline tracked a broad semiconductor selloff, as the 10-year Treasury yield held near 5.3% and crude oil climbed above $91, pressuring growth and tech names.

WULF fell -4.51% to $13.75 during regular trading, extending its recent slide. The primary catalyst was a jump in long-term Treasury yields, which raises borrowing costs for capital-hungry AI data-center builders.

ASTS fell -6.43% to about $56.75 in afternoon trading, extending a two-day slide from the prior session's $60.65 close. Primary catalyst: the FCC authorized rival SpaceX to build a direct-to-phone satellite constellation using its own spectrum, waiving the usual carrier-leasing requirement.

CIFR fell -6.8% during Thursday's regular session to about $13.57, down from the prior close of $14.56. The primary catalyst was a broad selloff in AI data-center and crypto-mining infrastructure names as long-term Treasury yields climbed, raising financing costs and shrinking the present value of future lease income.

IREN is down -7.52% to about $35.78 during regular trading, extending a slide after closing at $38.69 on Oct 7. The primary catalyst is a critical SemiAnalysis report citing repeated power outages, network disruptions, and storage failures at its legacy British Columbia sites (Prince George, Mackenzie).

NVDA fell -2.92% during Thursday's regular session, sliding to roughly $230.54 from a prior close of $237.47. Primary catalyst: an FT report that OpenAI's annualized revenue is ~$20B below prior figures, reigniting doubts about the sustainability of the AI-spending boom that drives Nvidia demand.

AMD fell -4.49% during regular market hours, dropping from a prior close of $645.86 to roughly $616.89. The decline was driven by a broad semiconductor selloff, with the sector ETF (SOXX) off about -2% and Nvidia also lower.

Micron (MU) is down roughly -4.70% to about $1,036.82 in regular Thursday trading, versus its prior close of $1,088.00. The decline follows a Taiwan union at its Taoyuan DRAM/HBM plant voting 99% to authorize a strike over a profit-sharing dispute, raising supply-risk concerns at a critical AI-memory hub.

INTC fell -5.55% on Thursday, sliding to $106.84 from the prior session's $113.12 close, with losses deepening through the regular session after a soft premarket. The primary catalyst was a macro-driven chip selloff: Brent crude jumped above $104/bbl after a tanker attack near the Strait of Hormuz, and the 10-year Treasury yield climbed toward 5.3%, its highest since 2002, pressuring high-multiple growth stocks.

SNDK fell -5.77% to roughly $1,594.74 in Thursday's regular session, down from the prior close of $1,692.42. The primary catalyst was a broad memory-chip selloff after Samsung's preliminary Q3 results missed elevated estimates (about 195T won revenue vs ~199T won expected).

Oracle (ORCL) shares fell roughly 16.7% over the last 30 days, dropping from about $162.52 on September 8 to near $135.33 in early October. The decline reversed a sharp summer rally, as the stock gave back much of a roughly 47% surge from its late-July lows even after Oracle posted strong fiscal Q1 results.

Oracle (ORCL) fell -5.73% to $135.33 during Thursday's regular session, down from a $143.56 prior close. Primary catalyst: a report that OpenAI's annualized revenue is near $50B, roughly $20B below the ~$70B previously signaled, rattling AI names broadly.

BBAI is down -6.37% in regular trading, sliding from a $2.51 prior close to about $2.35. No company-specific news drove the move; it extends a multi-day selloff from $2.74 on Oct 1.
