NEW YORK ( TheStreet) -- Investors have reset their sights on big banks such as Citigroup ( C) and Wells Fargo ( WFC) after they redeemed themselves by paying back the government's bailout money, but three of their smaller rivals are more attractive as investments. A fourth bank, rebounding from a loss, warrants waiting.Shares of Citigroup and Bank of America ( BAC) have fallen in the past month, even though a brace of large banks fully repaid the government's Troubled Asset Relief Program, or TARP. Wells Fargo has risen marginally. Investors are expecting big rebounds from the country's largest banks, with Thomas Villalta, manager of the Jones Villalta Opportunity Fund, saying Bank of America's stock could double this year. The following four banks are worthy of being placed on investors' watch list. Data were provided by SNL Financial.
