For investors, February is starting off even rougher than January. 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. It was the biggest one-day decline for the blue-chip index in more than seven months. And the drop followed the Dow’s worst January performance since 2009.
The market stumbled from the get-go and quickly turned into a slide as a spate of discouraging economic data on everything from manufacturing to auto sales to construction spending poured in. By late afternoon, the sell-off accelerated further, bringing the Dow down more than 7 percent for the year.
