I don't see this happening. You can only punish businesses for being successful so much. If Obama does this now the MA. senate vote/referendum will evolve into a shitstorm for his administration.
Their trading and direct investments accounted for 76% of their 2009 income and that's not just taking brokerage and spreads off client trades. Compare that to someone like Westpac which was 5%. I know a prop guy who's traded at a number of the wall street banks and he says I'm naive to think it's not about using client flow for the banks' own advantage. It's goodbye to Goldman glory trading years and back to reality of taking fees from advisory. Just annoyed I didn't put my money where my mouth was on my first post and taken the 4% drop in their stock - doh!
