U.S. stocks tumbled on Monday, pushing the Dow Jones industrial average down more than 320 points after reports of sluggish U.S growth added to investor worries about the global economy. The slump follows the Dow's worst January performance since 2009.
The market stumbled from the get-go, with U.S. markets opening lower after declines in European and Japanese indexes. Then it quickly turned into a slide as a spate of discouraging economic data on everything from manufacturing to auto sales to construction spending poured in.
The Dow Jones industrial average fell 326.05 points, or 2.1 percent, to 15,372.80.
The Standard & Poor's 500 index dropped 40.70 points, or 2.3 percent, to close at 1,741.89.
The Nasdaq composite fell 106.92 points, or 2.6 percent, to 3,996.96.
For the year so far:
The Dow is down 1,203.86 points, or 7.3 percent.
The S&P 500 is down 106.47 points, or 5.8 percent.
The Nasdaq is down 179.63 points, or 4.3 percent.
