An equation for determining the fair market value of a European-style option when the price movement on the underlying asset does not resemble a normal distribution. The gamma pricing model is intended to price options where the underlying asset has a distribution that is either long-tailed or skewed, where dramatic market moves occur with greater frequency than would be predicted by a normal distribution of returns.

While the Black-Scholes option pricing model is the best known, it does not provide accurate pricing results under all situations. In particular, the Black-Scholes model assumes that the underlying instrument has returns that are normally distributed. As a result, the Black-Scholes will misprice options on instruments that do not trade based on a normal distribution. Many alternative options pricing methods have been developed with the goal of providing more accurate pricing for real-world applications such as the Gamma Pricing Model. Generally speaking, the Gamma Pricing Model measures the gamma, which is how much fast the delta changes with respect to small changes in the underlying asset's price.

You can use this information to make better decisions about your investments because you know what factors affect them most significantly.

Some examples include stocks, commodities and foreign exchange.

While it is very accurate, it does have its limitations.

To account for situations where returns were not normally distributed or where dramatic market moves occurred more frequently than predicted by a normal distribution.

It assumes that returns are normally distributed and that there will be no dramatic market moves.

Alternative methods tend to be applied towards stocks, commodities and foreign exchange instruments .

Gamma measures how much fast delta changes with respect to small changes in the underlying asset's price.

Yes, there are many other methods used for calculating options prices besides these two models discussed here .

The gamma pricing model is an equation for determining the fair market value of a European-style option when the price movement on the underlying asset does not resemble a normal distribution.
