# Unlock the Power of Binomial Option Pricing Model in Excel with MarketXLS

## Introduction

Option pricing is a complex subject, and understanding the mechanics of how options work can be a daunting task. However, the Binomial Option Pricing Model is an excellent way to understand how options work and how they can be priced. Excel is a widely used tool in the financial industry, and it has a vast range of applications. One such application is the Binomial Option Pricing Model, which can be implemented in Excel to price options accurately. In this blog post, we will explore how to use MarketXLS to implement the Binomial Option Pricing Model in Excel and unlock its power.

## Understanding the Binomial Option Pricing Model

The Binomial Option Pricing Model (BOPM) is often used by finance practitioners and academics to value options and other derivative securities. With a BOPM, you can evaluate option prices and their sensitivities (or “Greeks”) with a few inputs, rather than relying on tedious market observations. The BOPM is based on the no-arbitrage principle, which states that no risk-free profit can be earned from entering into a set of transactions. This principle is often used to derive the model and its inputs, such as the stock price, volatility, strike price, and the risk-free rate.The best way to understand the BOPM is to think of a binomial lattice. It’s a series of nodes, sometimes referred to as a tree, that graphically depicts the different prices of a stock/asset. At each node, the asset price can either increase or decrease. The Bottom of the lattice is the expiration price, which is either the intrinsic value of the option or zero. The root of the tree is the node at the current moment in time.

For the more tech-savvy, the BOPM is fairly easy to implement in a spreadsheet or with the aid of a calculator. Most spreadsheets have model formulas already built into the cells, so you can quickly and easily input the variables and get the option price results. You can find free tutorials, Excel spreadsheet models and calculators on sites such as marketxls.com. On this site, you have the option to use the Binomial Option Pricing Model Excel spreadsheet, Black-Scholes Excel calculator, and the Option Premium Calculator. It’s important to understand the assumptions and principles behind this method of pricing options, as well as the stochastic differential equation and probability π.

## Advantages of the Binomial Option Pricing Model

The Binomial Option Pricing Model has several advantages over other option pricing models, such as the Black-Scholes model. One of the main advantages is its flexibility.

The Binomial Option Pricing Model can be used to price options in situations where the Black-Scholes model cannot be applied. For example, the Black-Scholes model assumes that the underlying asset price follows a log-normal distribution. However, in real-world situations, the underlying asset may not follow this distribution, and the Binomial Option Pricing Model can be used to account for this.

Another advantage of the Binomial Option Pricing Model is that it can be used to price options on assets that pay dividends. In the Black-Scholes model, the dividend yield is assumed to be zero, which can result in inaccurate pricing for assets that pay dividends. The Binomial Option Pricing Model allows for the inclusion of dividend yields, making it a more accurate pricing model for assets that pay dividends.

In addition, the Binomial Option Pricing Model is more flexible in terms of the number of time steps used in the model. The number of time steps used in the model can be increased to improve the accuracy of the pricing model. However, increasing the number of time steps increases the computational complexity of the model, making it more time-consuming to calculate the option price.

## Implementing the Binomial Option Pricing Model in Excel with MarketXLS

MarketXLS is an Excel add-in that provides a wide range of financial functions to users, including the ability to create your own option pricing model or use the Binomial Option Pricing Model Excel template provided on the MarketXLS website.

To use the BOPM template in Excel, you first need to download and install MarketXLS. Once you have installed MarketXLS, download the Binomial Option Pricing template from the website and enter the values of the parameters.

The parameters required by the BOPM template are spot price, strike price, time period for each node, risk-free interest rate, rate of upward movement in stock price, rate of downward movement in stock price, number of steps in the tree structure, call/put option, and dividend yield (optional).

After entering the required parameters, the template will calculate the option’s price using the Binomial Option Pricing Model. However, it’s important to note that the template accommodates only two time jumps. If further tree branches are required, customization is necessary.

Disclaimer: The Binomial Option Pricing Model is a complex pricing model, and the use of the template provided by MarketXLS does not guarantee accurate pricing or investment success.

## Conclusion

In conclusion, the Binomial Option Pricing Model is an excellent tool for understanding how options work and how they can be priced accurately. Using MarketXLS we can implement this model and unlock its power to make informed investment decisions.

One of the main advantages of using the Binomial Option Pricing Model is its flexibility. Unlike other models, it can be applied in situations where the Black-Scholes model cannot be used, such as in cases where the underlying asset pays dividends or when the asset price is not normally distributed. The model’s flexibility also allows us to adjust the number of time steps used in the model to improve pricing accuracy.

In summary, by using the Binomial Option Pricing Model and tools such as Excel and MarketXLS, investors and analysts can accurately price options and make informed investment decisions. The model’s flexibility and accuracy make it an essential tool in the financial industry for understanding how options work and how they can be priced.
