There are several financial stocks that are taking a beating today after a rash of downgrades by Merrill Lynch (NYSE: MER) this morning.

It has definitely been a couple of tough months for the financials as investors worried about what impact the declining housing market would have on their bottom lines. In the past week or so things have seemed to at least level off,, but according to Merrill Lynch there may still be some troubles ahead for a handful of Mid-Cap banks out there.

Banks that Merrill views as possessing "asset sensitive" balance sheets (meaning their assets reprice quicker than their liabilities) were on the top of the list of downgrades.
