Stocks move lower on Wall Street as coronavirus cases surge

Stocks moved broadly lower on Wall Street in early trading Wednesday as investors turned cautious after new coronavirus cases in the U.S. climbed to the highest level in two months.

The S&P 500 was down 1.3%, giving back all of its gains for the week. Financial, health care and communication services sector stocks accounted for a big slice of the losses.

The Dow Jones Industrial Average was down 391 points, or 1.5%, to 25,764. The Nasdaq, which was coming off its second all-time high this week, was down 0.9%. The Russell 2000 index of small company stocks gave up 2.2%.
