U.S. stocks fell further on Friday, pushing the S&P 500 and Nasdaq indexes down 2 percent as a brief boost from consumer sentiment data fizzled and investors kept booking profits after a recent run-up.

Among top drags were financials and technology shares, sectors that underpinned the market's rally off 12-year lows.

The Dow Jones industrial average <.DJI> dropped 142.09 points, or 1.79 percent, to 7,782.47. The Standard & Poor's 500 Index <.SPX> fell 16.04 points, or 1.93 percent, to 816.82. The Nasdaq Composite Index <.IXIC> slipped 33.35 points, or 2.10 percent, to 1,553.65.
