Stocks jumped Tuesday as easing worries about the fallout from debt struggles in Dubai and a mostly upbeat array of economic reports gave investors who had jumped out of the market last week reason to return. A drop in the dollar drove up commodities prices and lifted the stocks of energy and materials companies that produce them.

The Dow Jones industrial average rose 126.74, or 1.2 percent, to 10,471.58.

The Standard & Poor's 500 index rose 13.23, or 1.2 percent, to 1,108.86.

The Nasdaq composite index rose 31.21, or 1.5 percent, to 2,175.81.

The Dow is up 161.66, or 1.6 percent.
