The shares of Regions Financial Corporation (NYSE: RF) surged this afternoon after the regional bank said it expects to report a first-quarter profit. In a regulatory filing with the Securities and Exchange Commission (SEC), Chairman and CEO Dowd Ritter attributed the unexpectedly profitable quarter to recent strength in new account openings and customer deposit growth.

If Wall Street seems shocked by the news, it's because analysts were predicting Regions to swallow a quarterly loss of about $290 million, or 42 cents per share, according to Thomson Reuters. Plus, with nearly 5% of the equity's float sold short, it seems that many investors were also betting on the bank to report gloomy earnings.

It's a dismal day on Wall Street for financial stocks, and Regions Financial Corp. (NYSE: RF) is no exception. The Alabama-based bank today reported an eye-popping quarterly loss of $6.22 billion, or $9.01 per share, as results were pressured by a $6 billion writedown in its banking and Treasury operations.

On an operating basis, Regions' loss of 35 cents per share exceeded the consensus estimate for a loss of 20 cents per share. Net charge-offs for the quarter soared to $796 million, compared to $107.5 million in the year-ago period. Additionally, the company confessed to "emerging stress" in its Florida-based real estate and mortgage businesses.

"Although we're encouraged by steps the government has taken to stabilize the housing market and revitalize the economy, there is no quick fix for credit quality issues currently plaguing the financial services industry," commented Dowd Ritter, RF's chairman, president and chief executive officer.

Ritter added that he doesn't expect unemployment to peak or real estate values to bottom in 2009, and he warned that bank earnings won't improve until such a trough is reached. He doesn't foresee the need to seek new capital from the government, though Regions will look for opportunities to shore up its capital position as market conditions allow.
