The BlackScholes formula (also called BlackScholesMerton) was the first widely used model for option pricing. The model assumes the price of heavily traded assets follows a geometric Brownian motion with constant drift and volatility. This is in contrast to American options that can be exercised at any timeprior to expiration.A European option modsl used in order to reduce the variables in the equation.
This is acceptable, since most U.S. company stock options are notexercised until their expiration (vesting) date. They have closedform pricing equations, derived from the traditional BlackScholes analysis. This means American options are more expensive than European optionsAmerican options do not have closedform pricing equations. Accordingly, many numerical techniques and approximations for pricing American options have been developed.
Several of the most popular methods are summarized below. Some statistics required.We walk through the context and assumptions behind the Black Scholes equation then blaack a simple statistical tool to estimate the sholes that the terminal spot price (St) will be greater than or equal to the strike price (X).For a more detailed text based writeup please see the original writeup behind this video on FinanceTrainingCourse.com.
BlackScholes Option ModelThe BlackScholes Model was developed by three academics: Fischer Black, Myron Scholes and Robert Merton.
