While I'm not a fan of theirs, I have recently bought GS myself. Seems like its undervalued because they got lumped in with other financial stocks that had a lot of housing market exposure, while they don't and the market was a bit slow to realize it.
Specifically, I'm going for a bunch of day trading long positions on the dips--being that I expect it to eventually bounce its way back up to 180 or so making me bucks along the way.
I'm in at around 121 trying to sell around 126 or more tomorrow morning...wish me luck.
I'll bet you get 135+
