The Nasdaq 100 ETF (QQQ) lost 5.5%. Every chipmaker on the chart fell further than that.
Chipmakers have done much of the market’s heavy lifting in 2026. Nvidia, Micron, AMD and Intel added about $2.35 trillion in market value through October 15, 28% of the combined gain in S&P 500 stocks. A six-to-one gap in a single week shows how fast that trade can turn.
