Stocks making the biggest moves midday: Intel, Lumentum, Sandisk, Twilio, Coinbase & more

Friday’s trading showed sharp divergence: semiconductor stocks fell, with the VanEck Semiconductor ETF down 7%, while Intel dropped 29% after forecasting Q4 adjusted EPS of $0.25 versus $0.43 expected. Roblox and Reddit each fell 20% or more on disappointing guidance, while Regeneron gained 11% after beating Q3 estimates and raising its full-year gross-margin outlook to about 86%. FedEx Freight rose 15% on stronger Q4 guidance, and Coinbase and Robinhood fell after Binance reported an estimated $6.3 billion affected by a crypto hack.

Analysis

The broad AI-linked selloff looks more like a valuation and positioning reset than evidence, on this information alone, of cancelled compute demand. The distinction matters: if cloud customers trim capex, weakness can spread from accelerators into memory, optical components and networking; if not, indiscriminate selling may create better entry points in a later stabilization. Watch hyperscaler capex commentary and order revisions over the next 1–3 months, rather than extrapolating one session. Intel is a more company-specific caution: its guide miss raises execution and share-loss questions that a sector rebound would not resolve.

Near term, elevated correlation and gap risk argue against catching falling AI hardware names immediately. Over 6–18 months, a genuine capex slowdown would hit the ecosystem broadly, while supplier-specific exposure and customer concentration determine which names suffer most. Lumentum’s reported deal-premium comment is not a verified transaction term; do not underwrite MRVL or LITE on it without confirmation. Elsewhere, REGN’s improved product gross-margin outlook supports a more durable earnings case, though it is not equivalent to a consolidated margin forecast. RBLX’s weaker bookings outlook and TWLO’s slowing organic growth point to demand/growth risks that differ from the AI multiple reset.

Contrarian risk: after sharp single-day declines, consensus may overread a sector-wide move as proof that AI demand has broken. Falsification is sustained cuts to capex or supplier estimates—not simply another volatile session.

Key Decisions for Investors

• Do not add to ALAB, LITE, MU, ANET or NVDA solely because prices are down. Reassess after stabilization and hyperscaler capex/order commentary; reduce exposure if supplier estimates or customer spending plans are cut.
• Keep INTC separate from the AI-beta basket: avoid treating a sector bounce as a thesis repair. Revisit only if subsequent guidance and execution evidence address the gap versus its outlook; a sustained estimate-revision cycle lower would reinforce avoidance.
• Consider a beta-sized REGN-long/RBLX-short relative-value position for the next earnings-guidance cycle: REGN has improved product-margin guidance, while RBLX faces a bookings-growth hurdle. Keep it modest because sector risks differ; exit if REGN revises its outlook down or RBLX bookings expectations recover materially.
• Treat the LITE/MRVL deal-premium report as an alert, not a valuation anchor. Verify transaction terms and status before trading the spread; a confirmed deal or revised terms could quickly reverse event-driven positioning.
