# Option price models

The binomial option pricing model is an options valuation method developed in The binomial option pricing model uses an iterative procedure, allowing for the specification of nodes, or points option price models time, during the time span between the valuation date and the option's expiration date.

Key Takeaways The binomial option pricing model values options using an iterative approach utilizing multiple periods to value American options. With the model, there are two possible outcomes with each iteration—a move up or a move down that follow a binomial tree.

The model is intuitive and is used more frequently in practice than the well-known Black-Scholes model. The model reduces possibilities of price changes and removes the possibility for arbitrage. With a pricing model, the two outcomes are a move up, or a move down.

Option pricing theory uses variables stock price, exercise price, volatility, interest rate, time to expiration to theoretically value an option. Essentially, it provides an estimation of an option's fair value which traders incorporate into their strategies to maximize profits.

Yet these models can become complex in a multi-period model. In contrast to the Black-Scholes modelwhich provides a numerical result based on inputs, the binomial model allows for the calculation of the asset and the option for multiple periods along with the range of possible results for each period see below.

The advantage of this multi-period view is that the user can visualize the change in asset price from period to period and evaluate the option based on decisions made at different points in time. For a U.

If the option has a positive value, there is the possibility of exercise whereas, if the option has a value less than zero, it should be held for longer periods. However, a trader can incorporate different probabilities for each period based on new information obtained as time passes.

The tree is easy to model out mechanically, but the problem lies in the possible values the underlying asset can take in one period time. In a binomial tree model, the underlying asset can only be worth exactly one of two possible values, which is not realistic, as assets can be worth any number of values within any given range.

The binomial model allows for this flexibility; the Black-Scholes model does not. The binomial model can calculate what the price of the call option should be today.
