NEW YORK (MarketWatch) - U.S. stocks extended losses into a fourth session Thursday after the European Central Bank failed to live up to its president's advance billing. "It's disappointing they are not coming up with any concrete steps," said Andrew Fitzpatrick, director of investments at Hinsdale Associates Inc. The major indexes recouped much of their slide by the end of the day. After falling as many as 193 points, the Dow Jones Industrial Average DJIA-0.71% lost 92.18 points, or 0.7%, to end at 12,878.88. The S&P 500 index SPX-0.74% shed 10.32 points, or 0.8%, to 1,365. The Nasdaq CompositeCOMP-0.36% declined 10.44 points, or 0.4%, to 2,909.77.
