U.S. stocks opened sharply lower Friday, at risk of snapping a three-day winning streak as cases of the novel coronavirus continued to spiral higher.

The Dow Jones Industrial Average opened about 842 points, 3.7%, lower, near 21.711, while the S&P 500 was 89 points, 3.4%, lower, to start trading near 2,541. The Nasdaq Composite Index lost 243 points or 3.1%, opening at about 7,557. Shares of ViacomCBS Inc. slid at the open after the company warned COVID-19 could have a "material" impact on its operations.
