On November 19, U.S. stock markets fell sharply, with the Nasdaq Composite down 1.8% and the S&P 500 losing 1.2%, driven by steep drops in major AI-related technology stocks. Nvidia declined 3.5% ahead of its upcoming earnings, while other leading AI names fell around 3%. Analysts warned of late-cycle market risks tied to elevated valuations in the sector, adding to the broader weakness in tech shares seen throughout November.
