Facebook (FB +2.7%) is adding to Friday's gains, though shares remain down 19% from pre-earnings levels. The company's lock-up expiration begins on Aug. 15 (10% of outstanding shares), and additional releases arrive on Oct. 14 (9%) and Nov. 13 (49%). As Henry Blodget notes, Facebook's selloff will make it tough for the company to pitch a secondary offering to limit volatility, and could also prevent it from paying a $2.5B-$3B tax bill related to restricted stock by selling some of the shares.
