Auxilium Pharmaceuticals continued to rally on Friday even as the broader market fell, but option traders remain cautious.
optionMONSTER's Depth Charge system shows that 2,000 September 15 puts were bought for $1.50 and $1.60. The volume was well above the strike's open interest of 1,124 contracts before the session began, indicating that these are new positions.
These puts, which lock in the price where shares can be sold, were not tied to any stock trading identified by our systems on Friday. They could have been bought to protect existing long positions or to make speculative bets that the stock will fall by expiration in mid-September. (See our Education section)
