NEW YORK – U.S. stocks plunged in the biggest selloff since the financial crisis, driving the Dow Jones Industrial Average down more than 500 points, as investors appeared to lose faith in the ability of the world's policy makers to revive the global economy and stave off a rolling debt crisis in Europe.
The Dow cascaded lower throughout the session. It finished just off the lows with a 512.76-point decline, or 4.31%, to 11383.68, erasing all its gains for 2011. The slump of the past few weeks has driven the Dow down more than 10% from its May intraday highs, putting the index officially in correction territory.
It was the measure's biggest single-day loss since Dec. 1, 2008, when the Dow plunged 679.95 points at the height of the financial crisis, one of the market's worst days ever.
