The following video is part of our "Motley Fool Conversations" series, in which senior analyst Anand Chokkavelu, CFA, discusses topics across the investing world.

Warren Buffett has held significant amounts of bank stock and securities throughout the financial crisis. A few months ago, he added an investment in Bank of America (preferred shares plus warrants). In his latest shareholder letter, he gives positive outlooks for both Wells Fargo (a long-time common stock holding) and Bank of America as well as the banking industry as a whole. Anand explains.
