stocks have worst day since 9/11

from ap/yahoo: Stocks had their worst day of trading since the Sept. 11, 2001, terrorist attacks Tuesday, hurtling the Dow Jones industrials down more than 400 points on a worldwide tide of concern that the U.S. and Chinese economies are stumbling and that share prices have become overinflated.

The steepness of the market's drop, as well as its global breadth, signaled a possible correction after a long period of stable and steadily rising stock markets that had not been shaken by such a volatile day of trading in several years.
