An unprecedented drop in the stock price of Facebook’s parent firm sent other tech stocks down on Wall Street Thursday, abruptly halting the market’s four-day winning run. The 26.4% fall in Meta Platforms, as Facebook’s owner is now called, wiped more than $230 billion in market value, arguably the worst one-day loss in U.S. history. Other social media firms’ stocks, such as Twitter and Snap, have also fallen.

Because Meta is so highly valued, a large change in its stock price might influence larger market indices to fall or rise. The S&P 500 plummeted 2.4%, the most in over a year. The Nasdaq composite, which focuses on technology, fell 3.7%, the most since September 2020. The Dow Jones Industrial Average, which excludes Meta Platforms, dropped 1.5%.

Snap soared 54% and Pinterest vaulted 28% in after-market trading after each reported better-than-expected results.
