PUT ON A PUT

One of the four types of compound options, this is a put option on another underlying put option. The buyer of a put on a put has the right but not the obligation to sell the underlying put option - also known as the vanilla option - on the expiration date. This type of option is used when leverage is desired, and the trader is moderately bullish on the underlying asset. The value of a put on a put changes in direct proportion to the price of the underlying asset, i.e. it increases as the asset price increases, and decreases as the asset price decreases.
