The S&P 500 slid 1.2% in the early going Tuesday. The Dow Jones Industrial Average fell 431 points, or 0.8%. The Nasdaq composite sank 1.7%. Palantir Technologies, which had more than doubled so far this year, fell 10% despite reporting results that beat analysts’ forecasts. Nvidia also reversed course, falling 2.8%. European markets were lower and Asian markets fell overnight. Treasury yields edged lower in the bond market.
