Stocks extended losses on Tuesday after data showed contracts for pending home resales fell to a record low and factory orders declined more than expected in June.

The Dow Jones industrial average <.DJI> dropped 56.54 points, or 0.53 percent, to 10,617.84. The Standard & Poor's 500 Index <.SPX> fell 7.58 points, or 0.67 percent, to 1,118.28. The Nasdaq Composite Index <.IXIC> lost 19.28 points, or 0.84 percent, to 2,276.08.

The market opened lower as disappointing results from Dow Chemical Co and Procter & Gamble pushed investors to the sidelines after the S&P 500 hit a 10-week high.
