Unisys (UIS): An investor sold 2,500 July 17 calls for $2.15 and purchased about 6,400 July 19 calls for $0.95. Volume was below open interest in the 17s, indicating that a winning trade was rolled to the higher strike. It's especially bullish because they more than doubled the number of contracts owned. UIS rose 6.22 percent to $19.31. (See related story)
Bank of America (BAC): Some 23,000 January 10 calls were purchased, mostly for $0.40 and $0.41, but volume was far below open interest in the strike. BAC rose 3.62 percent to $8.02.
Vivus (VVUS): An investor sold 7,215 July 30 calls for $2.58 and bought an equal number of July 35s for $0.77. Volume was below open interest in both, so it probably results from a bullish call spread being closed. VVUS rose 0.70 percent to $28.72.
International Game Technology (IGT): A block of 12,000 July 15 puts was bought for $0.30, reflecting a belief the stock may head lower. IGT rose 1.36 percent to $15.61.
