More drops for superstars caught up in Wall Street’s artificial-intelligence frenzy knocked the U.S. stock market off its record highs.

The S&P 500 fell 1.1% Friday from its all-time high and had its worst day in three weeks. The weakness for tech stocks yanked the Nasdaq composite down a market-leading 1.7%, and the Dow Jones Industrial Average fell 0.5% from its own record set the day before.

Broadcom dragged the market lower even though the chip company reported a stronger profit for the latest quarter than analysts expected. Treasury yields rose to crank up the pressure on stocks.
