Bank of America (BAC -1.59%) and its stock have been on a hot streak, but some signs suggest that to the party will end sooner rather than later.

In this segment of The Motley Fool's financials-focused show, Where the Money Is, banking analyst David Hanson is joined by John Reeves to discuss John's upcoming piece on the long-term sustainability of Bank of America's business model.

John acknowledges that Bank of America has a powerful strategy in place, but he voices his concerns that reputational risk from its larger, less-profitable customer base could eventually affect the bank's relationships with its high-end, more profitable clientele.
