You can't really treat Facebook stock in that way, for two reasons:
a) They aren't putting in financial performance to impress investors. They are growing the company.
b) Treat it more like a resources stock were they have large mining leases and rights, have started exploration but are 2-3 years away from actually mining anything.
that's how the dot com boom happened in the turn of the century. Everybody thought the tech companies were like mining resources and silicon valley young stars were all getting rich as if they found the next petroleum site... except when it came to harvest profit, they couldn't meet the ultra high expectations... and the bubble goes "pop"
There are lots speculation that says Facebook is a bubble, I honestly think it has a lot more potentials as well, and it could potentially meet its expectations, but I don't think Mark Zuckerberg is exactly the right guy to meet the $50b or $70b expectation that investors believe.... I mean the guy is a legend and he continues to build amazing stuff for the world, but when it comes down to monetization, it's not cool, but maybe he'll find a cool way to make Facebook money.
Ye I think that is the difference. Most resources stocks have risk built into the price (from nationalization through to a drop in minerals demand) but Facebook hasn't done much wrong in the past 5-6 years.
a) They aren't putting in financial performance to impress investors. They are growing the company.
