On Wednesday morning, Bank of America (BAC -0.13%) will report first-quarter earnings. It is the last of the four biggest U.S. banks to report. Last week, investors were not overly impressed with the earnings from Wells Fargo and JPMorgan Chase as mortgage revenue fell. On the other hand, the market reacted quite positively to results reported by Citigroup (C -0.32%). So, the question is: Where does this leave B of A investors?

In this video, Motley Fool banking analyst David Hanson tells investors one major factor that the market will be watching when the megabank reports earnings.
