The S&P 500 fell 237 points, or 4.4%, to 5,159 as of 10:56 a.m. EST. The Dow Jones Industrial Average tumbled 1,475 points, or 3.6%, and the Nasdaq Composite slid 4.6%.
The indexes' free-fall Thursday was their biggest one-day drop since 2020, with more than $2 trillion in investor wealth erased from the S&P 500. The Dow and S&P 500 each sank more than 4% yesterday, while the tech-heavy Nasdaq plunged nearly 6%.
Drops of this magnitude aren't unheard of on Wall Street, but they're rare. Over the last 25 years, the S&P 500 has fallen 4% in a single day 38 times, according to Adam Turnquist, chief technical strategist for brokerage firm LPL Financial.
