Roll

1. To buy or sell an option and then later buy or sell the same option with a different strike price because one believes the price trend will continue. For example, suppose one buys a call option giving one the right but not the obligation to buy a stock at $10. One does this if one believes the underlying price will be above $10 when the option expires. However, if it appears near expiration that the option is well above $10 and likely will continue to, say, $20, one may buy another call option with a longer expiration and a strike price of $14 in order to capture higher gains. Rolling options may provide an investor with time to take full advantage of a prolonged price trend. It may be done with both call options and put options.

2. See: Roll over.
