This is a question regarding the WM call option (WMGQ), with strike 7.50 and expiration Jul 18, 2008: Last Friday, the volume for this contract was 231 and the open interest increased by 331 to 21,601. How is this possible? I assumed that nobody exercised the out of the money calls... I took all this info from http://quote.
