Tech sell-off hits chipmakers hardest
The S&P 500 closed at 7,659.44, down 84.62 points. The Nasdaq lost 572.99 points to 26,140.03, recording its first weekly decline in five weeks and its worst week since June. The Dow Jones Industrial Average held up better, slipping 175.28 points, or 0.3%, to 52,002.41.
Slightly more than half of S&P 500 stocks declined, but the losses were much more widespread within technology. Micron Technology, Advanced Micro Devices, Broadcom and Intel were among the hardest-hit chipmakers. Meta fell 3.7%, while Google parent Alphabet dropped 2.5%.
The selling came amid worries about how long the AI investment boom could continue. Higher bond yields have raised concerns about companies’ ability to keep borrowing and spending at the same pace. Those concerns formed the backdrop to the session, rather than establishing a single cause for every stock’s decline.
| Item | Details |
|---|---|
| Advanced Micro Devices | Shares fell 6.0% on October 16, 2026. |
| Intel | Shares fell 5.8%. |
| Micron Technology | Shares fell 5.6%. |
| Broadcom | Shares fell 4.5%. |
Elevated yields and oil prices complicate the backdrop
The 10-year Treasury yield slipped to 5.09% from 5.10% late Thursday. Although it had retreated from above 5.30% earlier in October, borrowing costs remained elevated. Consumer and wholesale inflation reports released during the week both exceeded economists’ expectations.
CME Group data put the probability of a December Federal Reserve rate increase at 74.3%, up from 50.2% a month earlier. Traders still expected the central bank to leave its short-term rate unchanged at its October meeting. These were market expectations, not announced policy decisions.
Brent crude rose 3.7% to settle at $109.86 a barrel as uncertainty over the U.S.-Iran conflict and oil flows through the Strait of Hormuz persisted. Exxon gained 2.5% and Chevron rose 2.6%, contrasting with the technology sector’s losses.
Company developments produce pockets of strength
Netflix fell 2.9%. The company’s announcement of Peter Rice’s appointment as chief content officer set October 26 as his start date, replacing Bela Bajaria. Netflix had also recently announced plans to cut about 6% of its workforce, or nearly 1,000 positions.
Alcoa rose 2.5% and Travelers gained 1.5% after reporting quarterly results that exceeded Wall Street forecasts. Those gains provided examples of earnings-related strength during a session dominated by technology losses.
Conclusion
The earnings season that began in earnest that week continues, providing the next check on the profit expectations that had helped U.S. stocks reach record highs.
