## Definition of 'Binomial Option Pricing'

Binomial option pricing is a mathematical model used to determine the value of a call or put option. The model is based on the assumption that the underlying asset's price follows a binomial distribution.

The binomial distribution is a discrete probability distribution that describes the number of successes in a sequence of independent experiments, each of which has a constant probability of success. In the case of option pricing, the experiments are the daily changes in the underlying asset's price, and the success is a daily increase in the price.

The binomial option pricing model works by calculating the probability of the underlying asset's price ending up at each of a number of possible values on the expiration date of the option. The value of the option is then determined by the payoffs that would be received if the option were exercised at each of these possible prices.

The binomial option pricing model is a relatively simple model, but it can be used to price options with a wide range of characteristics. It is also relatively easy to implement, making it a popular choice for option pricing in practice.

However, the binomial option pricing model has some limitations. One limitation is that it assumes that the underlying asset's price follows a binomial distribution. This assumption is not always accurate, and can lead to inaccurate option prices.

Another limitation of the binomial option pricing model is that it does not take into account the effects of volatility. Volatility is the degree of uncertainty in the underlying asset's price, and it can have a significant impact on option prices. The binomial option pricing model does not account for this effect, and can therefore lead to inaccurate option prices.

Despite its limitations, the binomial option pricing model is a valuable tool for option pricing. It is a relatively simple model that can be used to price options with a wide range of characteristics. It is also relatively easy to implement, making it a popular choice for option pricing in practice.
