The closing bell ended an ugly week without ending the argument. The S&P 500 fell 1.01% Friday to 7,457.69, the Nasdaq dropped 1.4% to 25,520.24, and the Dow shed 406 points — 0.77% — to 52,146.42. For the week: S&P down 1.6%, Nasdaq down 2.9%, Dow down 0.9%. The VanEck Semiconductor ETF lost almost 9% on the week, its third weekly decline in four, as the chip complex that entered a bear market Thursday found no Friday floor.
Here’s the part that should get your attention: the companies getting hit are mostly delivering. Netflix beat on earnings and came in a hair light on revenue — $12.56 billion against roughly $12.6 billion expected — with a softer-than-hoped third-quarter revenue forecast. The stock closed down almost 9%. Intuitive Surgical topped estimates on both profit and revenue; it lost 11.3% as investors fixated on slowing procedure growth and a stretched valuation. Chip-design software names Synopsys and Cadence fell 12% and 11.8%. Meanwhile Travelers, which posted a record quarter of unglamorous insurance profit, jumped 8.1% to lead the market.
The macro story hasn’t changed since Monday — it’s compounding. Moonshot’s Kimi K3, the giant open-weight model China unveiled in Shanghai this week, keeps chewing at the “more compute forever” thesis, and TSMC’s higher-than-expected capex guidance stoked margin worries down the whole supply chain. Global semiconductor stocks have now shed roughly $3.3 trillion in value since late June. The selling is hitting the most crowded positions hardest — the triple-digit year-to-date runners fell further than the megacaps — which looks less like a verdict on AI demand and more like a positioning unwind in the names everyone already owned.
Our take: The bar moved, and the market told you exactly where it moved to. In a tape priced for perfection, “slightly better than expected” now trades like a miss, while boring, present-tense cash — an insurer having a record quarter — gets bid like a growth stock. That’s not the AI trade dying. That’s the AI trade being repriced from faith to invoices. If you own the leaders, be honest about which side of that line your holdings sit on.
What to watch
- Hyperscaler earnings. Whether the big AI spenders reaffirm 2026 capex plans is the whole ballgame for semis. A single trimmed guide extends this selloff; unanimous reaffirmation likely ends it.
- TSMC’s next monthly revenue print and Nvidia’s upcoming report — the two hard-data checkpoints that can settle the “rotation vs. demand problem” debate.
- Whether the semiconductor ETFs stabilize after a third down week in four. Watch the breadth of any bounce: leadership-only rallies fade; broad ones stick.
