Facebook shares hit new low as lock-up period expires

Facebook’s stock plunged to an all-time low Thursday after the expiration of a lock-up period that has provided some early investors and insiders with an opportunity to exit.

Firms ranging from Accel Partners to Goldman Sachs, Zynga CEO Mark Pincus and Facebook board members James Breyer, Peter Thiel and Reid Hoffmanare among those free to sell stock they own. Microsoft Corp., an early Facebook investor, is another one, though it’s unlikely to sell because of partnerships it has with social-networking leader.
