If you buy FB for immediate profit and you dont do the due diligence, and falling the victim of the short, it is your problem.
The intention of FB is for the connection, and openness, and not the making money. Now the IPO is going to put a lot of pressure to FB for making more money. There are lots of ways to make money, especially easy to get money out of students pocket.
Don't worry, FB would make money, if shareholder push it to do so. So for the shorts, this would turn itself into money maker of FB...., No worry, hold your shares tight.
The problem with your statement is people already did their DD and they seen this falling knife. Kinda says something when even the CEO gets out, right? I'd be a little squeamish getting into a stock that not even a CEO likes. Not telling you what to do here but it's going to take a while for this to turn around imo,..J
