Stocks Slide as Netflix Guidance Disappoints and TSMC’s Capex Raise Stokes AI-Spending Worries
U.S. equities fell broadly on Thursday, July 17, in the heaviest one-day selloff in several weeks. The S&P 500 (SPY) declined 0.99% to $743.29, the Nasdaq-100 (QQQ) fell 1.50% to $695.33, the Dow (DIA) slipped a comparatively modest 0.77% to $520.81, and the Russell 2000 (IWM) declined 0.52%. The CBOE volatility-tracking VXX jumped 4.80%, while crude oil (USO) rose 3.91% on the day.
The session’s biggest single mover was Netflix, which fell 7.3% to $68.95 after reporting record second-quarter revenue of $12.56 billion, up 13% year over year and slightly ahead of analyst estimates. The stock dropped anyway because forward guidance disappointed: management guided third-quarter revenue growth to 11.7%, the company’s slowest pace in three years, alongside EPS guidance below consensus. Reports after the print noted shares fell as much as 9% in after-hours trading before settling into Thursday’s regular-session decline.
Semiconductor and AI-infrastructure names were broadly weaker. Taiwan Semiconductor raised its 2026 capital-expenditure forecast to $64 billion, a figure some investors read as confirmation that AI-buildout costs keep climbing rather than moderating. IBM fell sharply — its worst single-day decline since 1987 — after management acknowledged customers are redirecting software budgets toward hardware purchases. Alphabet fell roughly 2.2% following reports that its next-generation Gemini AI model is running behind its internal schedule, and Meta Platforms declined roughly 2.8% amid a new employee lawsuit tied to AI-linked layoffs and continued scrutiny of its $125–145 billion spending plans.
Elsewhere on the tape
Travelers rose 7.9% after posting earnings of $10.26 per share, roughly double analyst estimates, and UnitedHealth Group added 2.2% — two of the few clear winners in an otherwise red session. SanDisk, up more than 3,000% over the trailing twelve months on AI-storage demand, fell 3.99% in an apparent pullback. SpaceX declined roughly 5.4% as its post-IPO share lockup nears expiration.
