Stocks plunged again Wednesday as investors turned their attention back to the weak economy and Europe's debt problems. Most of the big gains that followed a Federal Reserve pledge to extend super-low interest rates vanished.
The Dow Jones industrial average fell 520 points, or 4.6 percent, to 10,719. The S&P 500 fell 52, or 4.4 percent, to 1,120, and the Nasdaq fell 101 points, or 4.1 percent, to 2,381.
On Tuesday, the Dow gained 429 points after the Fed said it planned to keep interest rates extremely low at least through the middle of 2013.
