Geron (GERN): More than 3,000 December 6 calls were sold, mostly for $0.65. Volume was below open interest, which suggests a trader is taking profits after a big run in the name. GERN fell 1.98 percent to $4.95.
Cemex (CX): More than 7,000 December 10 calls trade in the cement maker. They were initially purchased in bullish trades, followed by selling. CX fell 0.63 percent to $10.31.
Blackstone Group (BX): A block of 3,000 November 25 puts was sold for $0.03 against open interest and an equal number of December 25 puts was bought for $0.47. That suggests a protective position in the private-equity firm was closed and rolled forward in time. BX fell 1.39 percent to $26.25.
