Thursday

Worries about Europe's debt crisis sent stocks plunging, leaving major indexes with their first correction since the start of the bull market in March 2009. The declines accelerated late in the session, leaving both the Dow Jones Industrial Average and the S&P 500 off more than 10% from their recent highs. The Nasdaq Composite Index, which first moved into correction territory on May 7, has moved back and forth above the 10%-down threshold since. After its 4.1% drop today, it is now back below the mark. DJIA -376.36 Nasdaq -94.36 S&P 500 -43.46.
