Stocks Fall Before Nvidia’s High-Stakes AI Results: Markets Wrap

A selloff in the world’s largest technology companies drove stocks to their longest slide since August, underscoring the American market’s narrow reliance on a handful of growth giants.

The S&P 500 lost almost 1%, falling for a fourth straight day. In the run-up to Nvidia Corp.’s results, the shares sank 2.8%. The bar is getting higher for the chipmaker to convince investors that the billions of dollars spent on artificial intelligence will pay off. Its outlook could have significant implications due to the firm’s massive influence on major indexes.
