US tech stocks stumbled overnight as a trio of industry heavyweights — Netflix, Tesla and Texas Instruments — delivered results and forecasts that fell short of expectations. The tech-heavy Nasdaq slid 0.9%, while the S&P 500 and Dow Jones also lost ground, as investors digested a mix of weaker margins, cautious outlooks and one-off surprises that undercut the sector’s recent momentum.
The pullback comes at a delicate point for markets already contending with fresh trade jitters and a crowded earnings calendar. Reports that the Trump administration is considering new software export restrictions to China added to the downbeat mood, weighing on semiconductor and hardware names.
For now, the message is clear: Wall Street’s most closely watched companies are being judged not just on growth, but on how well they manage through higher costs, slower demand and geopolitical uncertainty.
Netflix slumps on tax hit and muted guidance
Netflix Inc (NASDAQ:NFLX, ETR:NFC) shares plunged about 10% after its September-quarter earnings missed forecasts, with a one-off tax dispute in Brazil slicing roughly 11% off operating income. Revenue came in at US$11.51 billion, just shy of expectations, and investors were underwhelmed by the lack of stronger forward guidance beyond 2025.
Management said margins would have exceeded guidance if not for the tax expense and pointed to solid subscriber engagement heading into the final season of Stranger Things. But after a 40% rally so far this year, traders wanted more — and the sell-off showed how unforgiving the market has become when high-priced growth names fail to clear the bar.
Tesla’s record revenue, thinner margins
Tesla Inc (NASDAQ:TSLA) reported record quarterly revenue of about US$28.1 billion, topping forecasts, but earnings fell short as profit margins narrowed sharply. The company delivered nearly 500,000 vehicles in the quarter — boosted by a rush of US buyers looking to secure an expiring EV tax credit — yet adjusted income dropped 29% from a year earlier.
The expiry of that subsidy now looms large, with analysts warning of weaker US demand through year-end. Competition from Chinese automakers such as BYD is intensifying, and Tesla’s shrinking margins have added to investor concerns that the company is prioritising volume over profitability.
Shares fell nearly 4% in after-hours trade.
Texas Instruments rattles the chip sector
Semiconductor stocks were also hit hard after Texas Instruments Inc (NASDAQ:TXN) issued weaker-than-expected guidance, warning of slower demand recovery across industrial and automotive markets. The analog chipmaker forecast December-quarter revenue roughly 2.5% below consensus and gross margins about 250 basis points lower than expected.
The company noted that while data centre orders are holding up, recovery across its core industrial and automotive markets has been far more tentative — a sign that tariffs and cautious spending are still weighing on the cycle.
The chipmaker’s stock dropped more than 5%, pulling down peers Micron Technology Inc (NASDAQ:MU), Onsemi (NASDAQ:ON) and Analog Devices Inc (NASDAQ:ADI), and weighing on European chipmakers ASML Holding NV (NASDAQ:ASML, ETR:ASME) and STMicroelectronics (NYSE:STM) in early trade.
A fragile mood for megacaps
The setbacks added to a cautious tone already clouded by reports that the Trump administration is considering new software export restrictions to China. Apple Inc (NASDAQ:AAPL, ETR:APC), Amazon.com Inc (NASDAQ:AMZN) and Nvidia Corp (NASDAQ:NVDA, ETR:NVD) each slipped between 0.5% and 1.8%, while the broader S&P 500 fell 0.5%.
The takeaway: Wall Street’s most influential tech names are under renewed scrutiny. Investors are rewarding margin resilience and guidance clarity — not just growth. With the earnings season in full swing and trade uncertainty resurfacing, it’s shaping up to be a more testing few weeks for Big Tech than markets had hoped.
