Facebook Stock Issued By Israeli Jeff Zuckerberg Has Lost 50% Of It’s Initial Price

Shares of Facebook are plunging to all-time lows after the expiration of a lock-up period, which has provided early investors and insiders with an opportunity to exit.

The stock fell 7%, or $1.49, to $19.71 in Thursday morning trading.

If the stock hits $19, it will have lost half its value since Facebook (FB) went public in May.
