Even with the turmoil caused by Wells Fargo and Deutsche Bank, nearly a quarter of all financial stocks rated by Weiss are still a BUY. Almost half of them (45.7 percent), fall under the HOLD category and 29.7 percent are a SELL.

Out of all rated financial stocks, only two were at the very top with an A+ Weiss investment rating: Farmers National Banc Corp. and Stock Yards Bancorp, Inc. Both provide excellent reward with low risk, and can offer consistent one-, three-, and five-year returns. However, due to a relatively small size they represent just over 0.01 percent of the financial sector. Stock Yard Bancorp has $742.1 million in market capitalization, and Farmers National Banc has only $291.6 million, while the average market capitalization for the sector is $4.9 billion.

Besides Framers National Banc and Stock Yard Bancorp, there are other 345 BUY companies that could be a good investment.
