I have a theory about FB stock but I maybe wrong.
My theory is that insiders who didnt want or couldnt sell their shares in the quite period sold their shares quietly at a discount to the under writers and brokerage firms. Now these guys are trying to pump the stock and sell it any sucker they could find. So if your broker is recommending FB stock to you just run.
Again, this is just my opinion.
Let FB fall and become a bargain. I agree, it is horribly manipulated, but if you want to watch massive manipulation in action, watch GMCR when earnings are released. There will be so many forces at work it will be ugly (shorts versus longs versus market makers).
