Stocks making the biggest moves midday: Micron, Tesla, Tripadvisor, AppLovin, Nvidia & more

A broad tech sell-off drove steep losses in AI infrastructure and semiconductor stocks: the SOXX ETF fell more than 9%, while several individual names dropped 12%–15%; Tesla fell 11% and SpaceX 9%. Company-specific moves were mixed: AppLovin rose 26% after beating revenue and adjusted EBITDA estimates, and EPAM gained 22% after raising earnings guidance and increasing its buyback authorization by $1.5 billion, while Tripadvisor fell 22% on leadership changes and a forecast of a low-teens sequential Q4 revenue decline. Guidance and earnings also drove sharp moves across other companies, including Motorola Solutions (+5%), Dutch Bros (-22%), and Fastly (-25%).

Analysis

The broad AI-infrastructure selloff is more consistent with crowded-position and duration-risk unwinds than evidence of cancelled projects: one political result in Texas is not yet a measurable change in customer capex. The second-order risk is tighter financing and lower equity-based funding capacity for leveraged compute providers such as CoreWeave, which could eventually delay orders to networking, optics, power and cooling suppliers. Conversely, if hyperscaler capex plans remain intact, the sharpest supplier drawdowns may rebound faster than the software and platform names whose earnings actually disappointed. Watch capex guidance and order/backlog conversion—not one-day price action.

The clearest company-level dispersion is advertising: AppLovin's operating beat contrasts with Snap's revenue and user shortfalls. That supports a relative-share-gain thesis, but the market may already have rewarded APP heavily; validate durability in the next quarter and avoid treating one report as proof of a persistent share shift. Qualcomm's weaker-than-expected near-term outlook matters more than its small quarterly beat, while Arm's beat did not protect it from multiple compression—evidence that results are being subordinated to positioning and forward expectations.

Over 1–3 months, the key catalysts are revisions to AI capex, advertising demand/share trends, and consumer same-store sales. Over 6–18 months, sustained AI spending would support infrastructure demand, but funding, power availability and project returns could constrain conversion. A broad tech rebound or reaffirmed capex would falsify the near-term de-risking thesis; weakening order growth would validate it. The tape is unusually volatile, so favor relative-value exposure over unhedged directional bets.

Key Decisions for Investors

• Consider a small, beta-hedged long APP / short SNAP pair on a post-reaction entry rather than chasing APP's gap. Thesis: relative monetization and execution improve APP's position versus Snap. Reassess after the next results; exit if APP's growth or EBITDA momentum fades, or Snap restores user growth and monetization. Valuation and borrow costs should be checked before sizing.
• Do not add to a broad AI-infrastructure short solely on this session. Put CRWV and a basket of exposed suppliers on watch; add only if hyperscaler capex guidance, supplier backlog/order conversion, or financing access deteriorates. A reaffirmation of capex alongside stabilization in the basket is a signal to cover or avoid the short.
• Favor guidance quality over headline beats: monitor QCOM's next-quarter revenue and handset demand for confirmation of the outlook pressure, and BROS same-store sales/EBITDA for whether its guidance cut is isolated or broadening. Avoid averaging down until those operating indicators stabilize.
• Keep exposure modest and use defined-risk structures where available: the unusually wide cross-stock moves create gap risk around earnings revisions and macro headlines, making outright single-name shorts vulnerable to sharp reversals.
