A trader bought 12,000 January 50 calls in a single print for $1.60 and sold two blocks of 6,000 January 55 calls for $0.60 and $0.65, according to OptionMonster's tracking systems. There was straight call buying in the November 49 strike, as well.

The January bullish call spread, which cost about $1 to establish, is looking for the stock to rally by expiration early next year. The independent energy and chemical company, which was spun off from Conoco in April, will release third-quarter earnings results on Oct. 31.

Phillips 66 shares gained 4.75 percent yesterday to close at $46.49, bouncing off its 50-day moving average after drifting lower this month. The stock came into June trading below $30 and ran all the way to a 52-week high of $48.22 on Sept. 14, with bullish option activity lighting up OptionMonster's systems repeatedly along the way.

Total option volume in the name yesterday was more than six times its daily average. Calls outpaced puts by 23 to 1.
