In the following video, Motley Fool financial analyst Matt Koppenheffer discusses how investors are looking at the nation's banks this earnings season. He notes that while some banks that have struggled to recover from the financial crisis and were hit particularly hard, such as Regions Financial (RF 2.01%), are able to thrill investors with only modestly positive earnings, others, like Bank of America (BAC 1.40%), have seen investor expectations ramp up to incredibly optimistic levels over the course of the past year, leaving the possibility of disappointing with their earnings reports high, even when the report is fairly positive.
