Option Pricing Models - How to Use Different Option

The above-mentioned classification of options is extremely important because choosing between European-style or American-style options will affect our choice for the option pricing model.

A formal definition of an option states that it is a type of contract between two parties that provides one party the right, but not the obligation, to buy or sell the underlying asset at a predetermined price before or at expiration day. There are two major types of options: calls and puts.

• Two ways to price options are the Black-Scholes model and the Binomial model. The Black-Scholes model is used to find to find a call price by using the current stock price, strike price, the volatility, risk free interest rate, and the time until the option expires. The Binomial model uses a tree of stock prices that is broken down into intervals. This tree represents the potential value of a stock from the present date and until the expiration. From this, one can find the value of the option with the strike price, volatility, risk free interest rate and the stock price at expiration date.

Assumptions
6. All the assumptions underlying the Black-Scholes model apply
7. The current value of the project and the variance in this value are known.

We generate the random number  ↋  and solve for S(T). Afterward, the process is similar to what we did for simulation in the binomial model: find the option’s payoff at the maturity and discount it to the present value.

Under the binomial model, we consider that the price of the underlying asset will either go up or down in the period. Given the possible prices of the underlying asset and the strike price of an option, we can calculate the payoff of the option under these scenarios, then discount these payoffs and find the value of that option as of today.

The simplest method to price the options is to use a binomial option pricing model. This model uses the assumption of perfectly efficient markets. Under this assumption, the model can price the option at each point of a specified time frame.
