The stalemate in debt talks dragged down stocks for a second day on Tuesday, and light volume showed investors remained reluctant to make bets despite another round of healthy earnings.

Based on the latest available data, the Dow Jones industrial average fell 90.37 points, or 0.72 percent, to 12,502.43. The Standard & Poor's 500-stock index was down 5.38 points, or 0.40 percent, at 1,332.05. The Nasdaq Composite Index  was down 2.84 points, or 0.10 percent, at 2,839.96.
