I am new to option and little confused with a microsoft May 2008 call. Zecco shows two symbols for the same strike price of $25. The premium on Symbol RISEY is $1 where as the other symbol for the same strike price is higher. Can any one pl. explain the differece between the two. In case if I am able to get RISEY for $1 will I be able to excersie that for $25.
pardon my ignorance
Thanks
