Ratio Calendar Spread

An option spread in which an investor buys options with a long maturity while buying more options with a shorter maturity. All options have the same strike price and may be either calls or puts, but not a combination of the two. A ratio calendar spread is used to reduce risk on price movements to the underlying security.
