JPMorgan's ( JPM) solid third-quarter earnings performance only adds to the pressure on Citi's ( C) embattled CEO Charles Prince. While Jamie Dimon's bank clearly isn't immune to the credit crunch that has crushed earnings at rivals including Citi and Merrill Lynch ( MER) -- JPMorgan reported a $1.3 billion writedown -- JPMorgan demonstrated how a bank can be big without being clumsy. JPMorgan made $3.4 billion, or 97 cents a share, for the quarter ended Sept. 30, up from the year-ago $3.3 billion, or 92 cents a share. The results, which beat Wall Street estimates by 7 cents, stood in sharp contrast to the sorry notes struck Monday by Prince at Citi, where net income tumbled 57% from a year ago due to some massive writedowns in leveraged lending and structured debt. So while Citi shares touched a new 52-week low in heavy trading Wednesday, dipping below $44 for the first time since September 2005, JPMorgan rose 4%. Prince famously said this summer that Citi would "keep dancing" to the music of easy money that fostered the huge buyout boom. But now that the leveraged-deal dancing's done, the bust has caused much embarrassment to Citi's chief -- to the point where the 57-year-old Prince's future is debated in the media daily. This morning rumors were floating that Citi's board may be in a special meeting to consider Prince's resignation. The company rebutted that report, but there's no denying that investors are eager to see the board take some sort of action.
