U.S. stocks are opened mixed as solid corporate earnings reports fail to offset worries about the debt crisis in Europe.

Big U.S. companies including 3M, Hershey and AT&T posted better-than-expected profits before the market opened Tuesday. U.S. Steel posted a wider loss than analysts had forecast, but its revenue beat Wall Street's estimates.

Apple, the biggest company by market value, reports after the market closes.

In Europe, stocks rose modestly after some of their worst losses in months. Weak bond auctions in Spain and Italy augured more pain ahead for those debt-strapped nations.

The Dow Jones industrial average rose 42 points to 12,969 in the first 10 minutes of trading. The Standard & Poor's 500 index rose 1 to 1,368. The Nasdaq composite index fell 5 to 2,965.
