Drops for computer chipmakers and other AI winners dragged down stock markets worldwide.
The S&P 500 fell 0.5 percent Thursday, even though more stocks rose within the index than fell. The Dow Jones Industrial Average dipped 0.2 percent, and the Nasdaq composite lost 1.5 percent.
Wall Street mostly rose after more U.S. companies reported better earnings for the latest quarter than analysts expected. But drops for Nvidia and other chip companies overshadowed them.
The losses were sharper in South Korea, where AI winners whipped lower.
Yields rose in the bond market, and oil prices erased an early gain to dip modestly.
