European stocks were lower, while the euro hit a three-week low on worries about a possible delay of a second bailout for Greece.

Banks were under pressure after Moody's warning that it may cut the ratings of 17 global and 114 European financial institutions because of more fragile funding conditions and increased regulatory burdens.

Among banks in the U.S., Moody's said it was reviewing the long-term ratings and standalone credit assessments of Bank of America , Citigroup , Goldman Sachs , JPMorgan Chase and Morgan Stanley .

Among earnings, General Motors posted its highest profit ever last year , though the automaker reported its quarterly results fell short of expectations.

Google could be in focus as the Chinese commerce ministry said it was reviewing Google's $12.5 billion deal to buy Motorola Mobility, as part of routine anti-monopoly checks.

Meanwhile, foreclosure rates gained again with one in every 624 U.S. households receiving a foreclosure filing in January, up 3 percent from the previous month, according to RealtyTrac.
