Thuldai,
Personally, I would not buy any financial stocks until the stress test result come out tomorrow afternoon. Having said that I looked at C and it looks like there is a reversal happening soon. Notice the doji in the candlestick at the top of the recent rally on the hourly chart. Doji is a bearish reversal sign when you are near a peak of a rally.
This is not a suggestion to sell or hold but to be careful!
