Stocks fell on Friday after the market opened, extending the previous session's steep losses, on fears the economy may slip back into recession and European banks could be severely damaged by another credit freeze.

The Dow Jones industrial average was down 88.09 points, or 0.80 percent, at 10,902.49. The Standard & Poor's 500 Index was down 8.72 points, or 0.76 percent, at 1,131.93. The Nasdaq Composite Index was down 17.68 points, or 0.74 percent, at 2,362.75.
