Markets Tuesday face the triple challenges of U.S. corporate earnings, Chinese economic reports and random headlines about Europe's sovereign debt crisis.

Early morning earnings reports are expected from Bank of America , Goldman Sachs , Coca-Cola, and Johnson and Johnson . IBM could also be a factor for the market Tuesday, weighing on the Dow after its nearly 4 percent after hours decline Monday.IBM said its profits rose 7 percent and it raised its 2011 outlook. But revenues were just shy of forecasts and it reported a disappointing number of signed service contracts, triggering profit taking in what has been a favorite stock setting an all-time high just last Friday.
