By Pete Najarian, co-founder of OptionMonsterNEW YORK -- LyondellBasell Industries ( LYB) is pushing a 52-week high, and traders are rolling with the name. OptionMonster's tracking systems detected buying in the October 55 calls for $1.15, while the September 52.50 calls were sold for 80 cents. It looks as if traders were closing the September contracts and opening a long position at the higher strike. Calls lock in the price where traders can buy shares in the chemicals company, which manufactures polymers, refines crude oil, and produces gasoline-blending components. By adjusting the options forward in time, the traders won't have to purchase the stock at expiration this Friday and can keep riding the rally without needing to own shares. The stock rose 1.08% to $52.50 Wednesday after RBC initiated coverage of the name with an outperform rating. At one point during the session it traded as high as $53.62, not far from the record high of $53.77 reached last week. More than 10,800 contracts traded in LyondellBasell Wednesday, compared with 2,500 in a typical session. Calls outnumbered puts by more than 4 to 1, indicating the bullish sentiment.
