Stocks open mixed now

U.S. stocks opened mixed Wednesday as investors considered the latest corporate earnings and awaited a second day of Congressional testimony from Federal Reserve chairman Ben Bernanke.

Dow Jones industrial average (INDU) was down 38 points, or 0.3%, shortly after the opening bell. The S&P 500 (SPX) fell 3 points, or 0.2%, and the Nasdaq (COMP) added 5 points or 0.2%.

Bank of America reported strong quarterly results before the opening bell. IBM and American Express will post their quarterly data after the close.

Bernanke will give his semi-annual monetary policy testimony before the House Financial Service Committee at 10 a.m. ET. It's unlikely he'll veer far from Tuesday's testimony before the Senate Banking Committee, when he raised concerns about Europe's debt crisis and the so-called "fiscal cliff" in the United States.

The Fed chief offered few hints about whether the Fed will engage in further economic stimulus, such as a new round of buying up securities, in the months to come.

David Abuaf, chief investment officer at Hefty Wealth Partners, said uneasiness remains rampant. "People just don't know what to expect yet," Abuaf said.

Anxieties continue to loom over Europe's debt crisis. A decision is not expected for another eight weeks from Germany's highest court on the legality of the eurozone's multinational bailout fund, the European Stability Mechanism. And in Spain, Finance Minister Cristóbal Montoro said tax collection must improve soon or the country won't be able to pay its public employees.

The International Monetary Fund said eurozone authorities need to act quickly to form a banking union and take other steps to prevent the crisis from escalating further.
