The stock market is having an excellent start to the short trading week on Tuesday. As of 11:20 a.m. EDT, the Dow Jones Industrial Average was up by 2.7% and the S&P 500 index was above 3,000 for the first time since early March.

Throughout the stock market rally since hitting bottom in late March, we've seen financial stocks -- particularly credit card companies -- outperform the market on strong days, and Tuesday wasn't an exception. American Express (NYSE: AXP) was nearly 6% higher on the day, while Discover (NYSE: DFS) and Capital One (NYSE: COF) were doing even better, up by 7.6% and 7.8%, respectively.
