US stocks tumbled again on Wednesday, leaving the benchmark S&P 500 on pace for a sixth straight decline as frustration with the euro zone's debt crisis coupled with weak Chinese factory data sank investor sentiment. Debt problems that have plagued Europe and the United States have pressured markets, knocking the S&P down more than 7 percent over the last six sessions.
The Dow Jones industrial average dropped 192.65 points, or 1.68 percent, to 11,301.07. The Standard & Poor's 500 Index fell 21.25 points, or 1.79 percent, to 1,166.79. The Nasdaq Composite Index lost 50.51 points, or 2.00 percent, to 2,470.77. All 10 S&P sectors were negative, with financials among the biggest decliners over concerns about exposure to European debt. J.P. Morgan Chase & Co dropped 3.1 percent to $28.49 and Citigroup Inc lost 4.4 percent to $23.38.
