NEW YORK ( TheStreet) -- Financial stocks have been rallying. With banks reporting improving earnings, financial funds have gained 14.7% this year, outdoing the S&P 500 by 4 percentage points, according to Morningstar.Some mutual fund portfolio managers argue that financial stocks can continue climbing. The managers have big stakes in banks, insurance companies and money managers. Funds with sizable financial holdings include Davis New York Venture ( NYVTX), Haverford Quality Growth Stock ( HAVGX) and Snow Capital Opportunity ( SNOAX). The bullish mutual funds are in a distinct minority. Many portfolio managers remain wary of the sector, concerned that profits could be hurt by new regulations in the U.S. and the continuing crisis in Europe. But Nate Snyder, portfolio manager of Snow Capital Opportunity, argues that the fears are excessive. "We have endured the worst financial crisis in 70 years," he says. "The next big crisis is not likely for another 70 years. From here on, everything should improve."
