The Dow tumbled more than 300 points Monday afternoon, or almost 2%, after a much worse-than-expected reading on manufacturing activity. The S&P 500 and Nasdaq were down more than 2%.
Companies like Microsoft and G.E. were also down 3 percent. And AT&T fell more than 4 percent. So far this year, the Dow is down 1,200 points.
