Before you make a claim for a number like a pps of $400 why don't you look for a more reasonable number like $30. Explain how it will reach that point. Then your post is not inane.
For FB to be $400, it would have to have an income of around $80 billion and with new shares issued it would be more like $100 billion. Who knows how much revenue would be but right now FB is having a hard time reaching 1 billion dollars income and none of us really have an idea of how they could report 2 billion but you can maybe make a stab at that and at least it would be more realistic.
There are many people with different convictions on this but posts like this are just screaming out numbers and are not really useful to people here.
To me Facebook is like a web site where people connect. I know it has the user base at this time, but it's still just a web site. I just don't see Facebook being worth so much money. I'm betting on put options since I believe that FB is overvalued at this time.
