U.S. stocks were little changed on Tuesday as strong earnings offset German demands for new austerity measures from Greece that prompted more worries over shaky Greek debt.

Financial stocks were also in focus as the chief executive of Goldman Sachs Group Inc testified before a Senate subcommittee examining Goldman's role in the financial crisis. The stock was up 0.5 percent to $152.76.

Greek bonds sank to new lows as investors speculated on the possibility the region's rich governments will fail to agree on a bailout in time to prevent a Greek sovereign debt default.

and 3M Co posted better-than-expected quarterly profits and raised their full-year outlooks. 3M gained 2 percent to $89.08, while fellow Dow component DuPont fell 1 percent at $40.56.

On the data front, home prices fell in the month of February, but rose from a year ago for the first time in more than three years, Standard & Poor's said. Separately, the Conference Board reported consumer confidence was up more than expected in April to the highest level since September 2008.
