Stocks close lower, Dow falls more than 300 points as Salesforce plunges 20%: Live updates

Stocks closed lower Thursday as Salesforce logged its worst day in around two decades. Traders also looked ahead to the release of key U.S. inflation data.

The Dow Jones Industrial Average slid 330.06 points, or 0.86%, to 38,111.48. The S&P 500 lost 0.6% to close at 5,235.48. The Nasdaq Composite dipped 1.08% to 16,737.08, underscoring the weakness in technology names.

Salesforce plunged 19.7% after missing revenue expectations for the fiscal first quarter and providing a weak outlook, marking its worst session since 2004. Artificial intelligence darling Nvidia also slid more than 3%, notching its first negative session following its blockbuster earnings report last week. Microsoft declined more than 3% for its worst day since October.

Those drops dragged on the major indexes given the companies' weight in the market, masking strength elsewhere. For example, though the S&P 500 as a whole took a leg down, more than 360 member stocks recorded gains. Meanwhile, the small cap-focused Russell 2000 rose 1%.

Thursday's moves come amid a tough, holiday-shortened trading week. The S&P 500 has slipped around 1.3%, while the Nasdaq Composite has shed 1.1%, putting both on track to snap five-week winning streaks. The Dow has tumbled more than 2%, on pace for its second straight losing week.

"At this point, we're kind of in that one step forward, one step back kind of mentality," said Jason Heller, executive vice president at Coastal Wealth. Following recent all-time highs, traders are "taking some risk off the table."

An uptick in the 10-year Treasury yield has hurt investor sentiment this week. Higher yields can be bad news for stock investors, as they reduce the multiples traders are willing to pay for equities and make safer
