Stryker pulled back after running hard in January, and now the bulls are looking for more upside.
OptionMONSTER's tracking systems showed the purchase of some 2,100 March 65 calls for $0.60. Volume was more than triple previous open interest at the strike.
Calls lock in the price where investors can buy shares, so they have the potential to generate significant leverage in the event of a rally. But these options also will become worthless if the stock doesn't move by the mid-March expiration.
