Downbeat consumer sentiment data and weak revenues from GE and two big banks slammed stocks on Friday, driving major indexes down more than 2.5 percent.

The Dow Jones industrial average <.DJI> slid 261.41 points, or 2.52 percent, to end unofficially at 10,097.90. The Standard & Poor's 500 Index <.SPX> dropped 31.60 points, or 2.88 percent, to finish unofficially at 1,064.88. The Nasdaq Composite Index <.IXIC> fell 70.03 points, or 3.11 percent, to close unofficially at 2,179.05.

The three major U.S. stock indexes erased their weekly gains; each index closed down roughly 1 percent for the week.
