Wall St plummets: Dow slides 1033 pts, S&P drops by 100 amid selloff

The US stocks plunged around 4 percent on Thursday in another dramatic session, confirming a correction that has thrown the market's nearly nine-year bull run off course.

The bottom of this recent slide remained elusive for investors, who have been whipsawed this week by huge swings that have shaken a market that had only climbed steadily for months.

With Thursday's drops, the benchmark S&P 500 and the Dow industrials confirmed they were in correction territory, both falling more than 10 percent from Jan. 26 record highs. The S&P 500 slumped 3.8 percent on Thursday, while the Dow dropped 4.2 percent as losses accelerated late in the trading day.
