NEW YORK, May 21 Wall Street was slightly higher in volatile trade on Friday as the S&P 500 fell below the level reached during the market "flash crash" earlier this month before muscling into positive territory.
The S&P rebounded from several days of declines that had driven the index down 12 percent from an April high.
Stocks fell at the open as concerns over the euro-zone debt crisis and uncertainty over the effects of U.S. financial reform fractured investor confidence in risky assets.
Bank shares rose a day after the U.S. Senate approved a sweeping Wall Street reform bill, capping months of wrangling over the biggest overhaul of financial regulation since the 1930s. For details, see [ID:nN20244272]
JP Morgan Chase & Co (JPM.N) advanced 3.3 percent to $39.08, and Bank of America Corp (BAC.N) rose 1.4 percent to $15.50. The KBW Bank index .BKX gained 1 percent.
"We were way oversold coming into today," said Angel Mata, managing director of listed equity trading at Stifel Nicolaus Capital Markets in Baltimore. "What we are seeing is a bounce after having some tremendous selling pressure in the market."
The Dow Jones industrial average .DJI gained 19.80 points, or 0.20 percent, to 10,087.81. The Standard & Poor's 500 Index .SPX rose 5.36 points, or 0.50 percent, to 1,076.95. The Nasdaq Composite Index .IXIC climbed 7.83 points, or 0.36 percent, to 2,211.84.
The S&P hit a session low of 1055.90 before shooting as high as 1080.67 within a half-hour, led by the turnaround in financial stocks.
The closing low on the benchmark index for the year was 1056.74 in February.
At Thursday's closing level, the S&P 500's 14-day Relative Strength Index had fallen below 30 for the first time since the benchmark hit 12-year lows in March 2009, indicating the index was oversold.
Germany's parliament approved a plan to allow its government to contribute to a 750 billion euro ($940 billion) emergency debt package despite wide public opposition to the move. [ID:nLDE64K0S1]
The Chicago Board Options Exchange Volatility index .VIX, Wall Street's so-called fear gauge, fell 6.2 percent to 42.97 after hitting a high of $48.20.
May equity options and some options on stock indexes will stop trading at Friday's close and settle on Saturday, which may increase volatility. (Reporting by Chuck Mikolajczak; editing by Jeffrey Benkoe)
