With the S&P 500 (^GSPC 0.07%) down nearly 3% in the past week, and the S&P's bank stocks down 3.5%, Motley Fool financials analysts Matt Koppenheffer and David Hanson take a look at which banks may be bucking the downward trend this week. They highlight one banking merger that's gone against this trend in a big way, discuss why Canadian banks are often viewed as a safer bet in times of turmoil, and tell us why Wells Fargo (WFC -0.32%) consistently keeps its head above water, even in rough seas. 

Wells Fargo's dedication to solid, conservative banking helped it vastly outperform its peers during the financial meltdown. Today, Wells is the same great bank as ever, but with its stock trading at a premium to the rest of the industry, is there still room to buy, or is it time to cash in your gains?
