Financial stocks were volatile in trading Wednesday, after weak demand at an auction of federal bonds weighed on a rally sparked by stronger-than-expected economic data.

Treasury's $34 billion auction of five-year notes was weaker than expected and far weaker than Tuesday's $40 billion auction of two-year notes, according to RealMoney.com contributor Tony Crescenzi. With the government borrowing heavily to fund its bailout efforts, including the Public-Private Investment Program unveiled Monday that will help private investors buy toxic assets weighing on bank balance sheets, a rally in the financials and the wider market fizzled.

The Commerce Department on Wednesday reported that orders for durable goods, or manufactured products expected to last at least three years, increased 3.4% last month. The consensus analyst estimate was a drop of2%. The department also reported that new home sales rose to a seasonally adjusted annual rate of 337,000 from an upwardly revised January figure of 322,000. The results, while better than the drop to 300,000 units that analysts expected, still were the second-worst on record.

Stocks that had been trading higher earlier in the day gave up gains. The NYSE Financial Sector Index closed up 2.6% to 3,010.

Bank of America ( BAC) shares closed up 6.7% to $7.70 and Wells Fargo ( WFC) shares added 5.9% to $16.42, after Moody's Investors Service cut their credit ratings.

JPMorgan Chase's ( JPM) stock closed up 8.2% to $28.56.

Troubled Citigroup ( C) shares finished down 2% to $2.95, after Treasury Secretary Timothy Geithner said in a speech Wednesday that the Obama administration wanted to push Congress to grant new powers quickly that would allow the administration the power to take over financial institutions whose collapse could jeopardize the U.S. economy, like troubled insurance giant American International Group ( AIG).

AIG shares shed 13.7% to $1.20.
