De Molina's strength was in communicating with investors, the analyst wrote. Credit Suisse analyst Christopher Mutascio, who has an "Outperform" rating on shares, likewise said de Molina is well liked by analysts for his candor. "His sudden departure after taking on the role of CFO roughly a year ago will take many by surprise and could certainly conjure up concerns about the quarter," wrote Mutascio. But Merrill Lynch analyst Edward Najarian, who has a "Buy" rating on shares, said he doesn't expect the CFO change to affect the company's finances or structure. "While this news could cause BAC shares to decline on Monday, we expect any weakness to be modest and short-lived," wrote Najarian.
