NEW YORK>> Wall Street swung back down on Tuesday, and its former superstars once again led the way.

The S&P 500 dropped 1.1% for its latest swerve in a scary ride, where it tumbled by 10% from its record and then rallied for two straight days. The Dow Jones Industrial Average fell 260 points, or 0.6%, and the Nasdaq composite sank 1.7%.

Tesla was one of the heaviest weights on the market after falling 5.3%. The electric-vehicle maker’s stock has been struggling on worries that it will lose sales because of anger at its CEO, Elon Musk, who has been leading efforts to cut spending by the U.S. government. EV rivals, meanwhile, continue to chip away at its business. China’s BYD on Monday announced an ultra-fast charging system that it says is nearly as quick as a gasoline fill-up.

Alphabet sank 2.2% after the owner of Google said it would buy cybersecurity firm Wiz for $32 billion. It would be the company’s most expensive purchase in its 26-year history, and it could boost the tech giant’s in-house cloud computing amid burgeoning artificial-intelligence growth.

The drop for Big Tech continues a trend that’s taken hold in the market’s recent sell-off: Stocks whose momentum had earlier seemed unstoppable have since dropped sharply following criticism they had simply grown too expensive.

Chief among them have been stocks that zoomed higher in the frenzy around AI technology. Nvidia fell 3.3% as it hosted an event known as “AI Woodstock.” Super Micro Computer, which makes servers, lost 9.6%. Palantir Technologies, which offers an AI platform for customers, sank 4%.
