optionMONSTER's Heat Seeker tracking system detected the purchase of 3,000 January 36 calls in a single print for $0.31 yesterday. This is a new position, as the volume was above the strike's open interest of 2,564 contracts before the session began.
VLO rose 0.45 percent yesterday to close at $33.83. Shares had gone on a scorching run from $20 to its 52-week high of $34.49 from early June to mid-September, then pulled back to support at $28 before resuming its climb.
Yesterday's long calls, which lock in the price where traders can buy the stock, are looking for VLO to rise roughly 9 percent in the next three weeks. If the shares are below the $36 strike price at that time, the calls will expire worthless. (See our Education section)
Overall calls in the name outnumbered puts by nearly 4 to 1.
