I have been concerned about the strength of the banks insured by the FDIC. One commenter asked whether there were any good banks. To that end, I have identified four that might be among the more solid. I did this by screening for regional banks with profit margins over 30%, a stock market capitalizations above $500 million, and a recent improvement in operating performance accompanied by a rise in stock price.

Here are four to consider. The list below includes their name, location, and (net profit margin):

• City Holdings (NASDAQ: CHCO) Charleston, WV (33.7%)
• First Midwest Bankcorp (NASDAQ: FMBI) Itasca, IL (32.6%)
• Valley National (NYSE: VLY) Wayne, NJ (34.4%)
• Prosperity Bancshares (NASDAQ: PRSP) Houston, TX (35.0%)

If you're nervous about where your money is currently deposited, these four might be worth considering. But before you move your money, it would be worth reading their most recent annual reports and quarterly financial statements. Red flags to watch out for include negative cash flow; rising charge-offs and loan loss reserves, and lawsuits.

MOST NOTEWORTHY: EastGroup Properties, Take-Two and Calumet Specialty were today's noteworthy downgrades:

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.

The banks that Merrill discussed today are those that the company views as being vulnerable to margin deterioration in the face of lowered earnings expectations and the possibility of future rate cuts by the Federal Reserve. 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.

Here are a couple of the banks to Merrill lowered today:

• City National Corp (NYSE: CYN) - downgraded to a sell from a neutral; stock is down 1.5%
  
• Cullen/Frost Bankers Inc. (NYSE: CFR) - downgraded to a sell from a neutral; stock is down 3.3%
  
• First Midwest Bancorp (NASDAQ: FMBI) - downgraded to a sell from a neutral; stock is down 3.1%
  
• Texas Capital Bancshares (NASDAQ: TCBI) - downgraded to a sell from a neutral; stock is down 6.7%
