Dow makes largest one-day gain in history

Just when it looked like the stock market was headed for an overdue correction, the Dow Jones industrial average exploded up 499 points to 10,630.60 on Thursday, its largest single-day jump in history

Technology stocks, which spent most of the day in the red, caught fire in late trading as the Nasdaq composite roared up 135 points to finish at 4,717.29. Better than expected economic news, combined with a generally oversold market, made Thursday's rally possible.

The Producer Price Index, which shows inflation at the wholesale level, came in at 0.3 percent for February. The report was slightly ahead of estimates and clearly helped lift stocks. "This is just a real awakening to the fact that the old stocks weren't dead," said Larry Rice, chief investment officer at Josephthal Lyon & Ross. "I find it incredulous that you can take a two-year bear market in the Dow and reverse it in two days. So I'm not sure this is too sustainable past another day or so before the money flows back into Nasdaq."
