U.S. stocks fell at the open on Friday as proposed sweeping restrictions on U.S. banks and the delayed confirmation of Fed Chairman Ben Bernanke unnerved investors after a 10-month rally.

The Dow Jones industrial average <.DJI> was down 57.21 points, or 0.55 percent, at 10,332.67. The Standard & Poor's 500 Index <.SPX> dipped 4.94 points, or 0.44 percent, at 1,111.54. The Nasdaq Composite Index <.IXIC> fell 9.98 points, or 0.44 percent, at 2,255.72.
