Stocks plunged on Wall Street again today in the latest reverberations of the crunch in the American credit market.
At 1 p.m., the Dow Jones industrial average was down more than 330 points, or 2.5 percent. And the Standard & Poor’s 500-stock index and the Nasdaq composite were down by comparable amounts, bringing the losses for all three indexes to more than 10 percent since their peak last month — the threshold at which the market’s fall is considered to have reached a correction.
