Today Citigroup (C), the second big bank to report its first quarter earnings, reported profit growth that exceeded analyst expectations. That's caused most of the financial stocks on the Dow Jones to get a large bump in price this morning. Bank of America (BAC), Goldman Sachs (GS), and American Express (AXP) are all up at least 1%. Citigroup is up almost 5%, as of 12:25 PM New York Time. It seems then that many who warned of "regulatory woes" over-estimated the effect of Dodd-Frank on the markets.
