Chip Stocks Face Worst Two-Day Decline Since October

Chip stocks sold off sharply, dragging U.S. markets lower as the semiconductor rally paused. The iShares Semiconductor ETF (SOXX) fell 6.34% over the past two trading days—its worst two-day drop since Oct. 10, 2025, when it fell 6.71%—highlighting broad weakness in names such as Nvidia and Advanced Micro Devices. The sector downturn weighed on major indices, with the Dow, S&P 500 and Nasdaq all finishing lower. The piece frames the move as a meaningful sector-led pullback rather than an isolated event, increasing near-term downside risk for semiconductors and related tech stocks.
