How to build a Black Scholes VBA Option Pricer

Introduction

The Black Scholes Model of Stock Prices

Fischer Black, Myron Scholes and Robert Merton made significant advances in the development of choices pricers with the papers published in 1973.

According to the Black Scholes unit, the price course of shares is described by the pursuing stochastic partial differential formula

The development of a transparent and reasonably robust options pricing unit underpinned the transformational growth of the options industry over the years to follow.

dS = (r - q -1/2sigma^2)dt + sigma dz

In this record the key presumptions of the Dark Scholes version are described, the analytical solutions to the Black Scholes differential equations stated.

in which dz is known as a standard Brownian motion, defined by dz = epsilon * sqrt(dt) where epsilon is a common normal randomly variable; dS is the difference in stock value, r is the risk-free rate of interest, q is a dividend of the stock, sigma the movements of the stock.

The version implies that dS/S follows a typical distribution with mean

Having shown the solutions, this kind of document shows the development of the VBA end user defined features required for rendering of Dark Scholes VBA analytical pricing solutions using Excel.

r - q -1/2sigma^2, and standard change sigma 5. epsilon 2. sqrt(dt))

The key benefits of defining a personalized function in Excel pertaining to using Dark-colored Scholes in VBA contain

St = S0 2. exp( (r – q - ½ sigma^2) dt + sigma * epsilon * sqrt(dt))
