Remember when Facebook was the hot stock a few months ago? Look at it now:
A bit of a struggle to say the least. Good thing you didn't buy any stock a few months ago....or did you?
As for Mr. Zuckerberg and his half a billion shares, he has lost about $9 BILLION in 3 months. That's gotta hurt. Until you realize that Facebook can lose 99% of its current value of $20.04 and he can still be worth over $100 million. I don't feel too bad for you sir!
