U.S. stocks plummeted on Monday, briefly sending the S&P 500 and Nasdaq down more than 8 percent, after the U.S. House of Representatives rejected a $700 billion financial-sector bailout plan, renewing fear about frozen world credit markets and the outlook for the global economy.

The bailout's failure in the House added to losses suffered after Wachovia Corp became the latest major U.S. bank to succumb to the global credit crisis.
