The Dow plummeted nearly 1,200 points on Thursday — its biggest one-day point drop ever — as worries over the coronavirus possibly spreading sent stocks spiraling lower. The 30-stock average closed in correction territory along with the S&P 500 and Nasdaq Composite.

Concerns over the coronavirus have also led several companies to issue earnings and revenue warnings. Microsoft said Wednesday one of its key divisions may not meet the company’s previous revenue guidance. PayPal also warned about its outlook on Thursday.
