Sealed Air has been rocking since August, and the bulls apparently think that it will keep on rolling.
OptionMonster's real-time scanners detected the purchase of 5,100 January 20 calls late in Friday's session for $3.60 and $3.70 in volume that dwarfed the strike's previous open interest of just 137 contracts. Sealed Air immediately jolted higher and ended the session up 0.77 percent to $22.38.
These calls lock in the price where investors can buy shares. That will provide significant leverage if the bubble-wrap maker continues to climb this year, but even a relatively small decline could erase all their value.
