Discuss Advanced Derivatives – Computational Methods for Option Pricing.
The traditional Black-Scholes model is often used to price standard options, but it cannot be used to price advanced derivatives because it assumes that stock prices follow a normal distribution, which is not always the case in reality. Therefore, more advanced models are required to price these complex instruments accurately.
There are several computational methods that can be used to price advanced derivatives. The most commonly used methods are:
Monte Carlo simulation: This method involves generating rando

Finite difference methods: This method involves approximating the option’s value by solving a partial differential equation. This method is particularly useful for pricing options with early exercise features, such as American options.
Binomial tree methods: This method involves building a binomial tree to model the possible stock price movements and calculating the option’s expected payoff at each node. This method is particularly useful for pricing options with discrete features, such as barrier options.
Fourier transform methods: This method involves transforming the option’s payoff function into the frequency domain and using numerical integration techniques to calculate the option’s value. This method is particularly useful for pricing options with complex payoff structures, such as Asian options.
In addition to these methods, there are also several specialized numerical techniques that have been developed for pricing specific types of advanced derivatives. For example, the Longstaff-Schwartz algorithm is commonly used to price American options, while the fast Fourier transform method is often used to price options on commodity futures.
Overall, the pricing of advanced derivatives requires specialized computational methods that are tailored to the specific characteristics of the instrument being priced. These methods are constantly evolving as financial markets become more complex and new financial instruments are developed.
