Black Scholes Model

The Black–Scholes model is a mathematical model of the market for an equity, in which the equity’s price is a stochastic process. The model makes the following assumptions:

* It is possible to borrow and lend cash at a known constant risk-free interest rate.
* The price of the equity follows a geometric Brownian motion with constant drift and volatility.

Monte Carlo Simulation In Excel

Monte Carlo methods are a class of computational algorithms that rely on repeated random sampling to compute their results. The term Monte Carlo Method was coined by S. Ulam and Nicholas Metropolis in reference to games of chance, a popular attraction in Monte Carlo. You can use Excel to imitate real life situations and make predictions. When you create a model in Excel, you define the input parameters and create equations that use those inputs to give you a set of outputs (or response variables).

Calculating Historical Volatility

The goal is to calculate historical volatility in a robust way. Sometimes volatility over the past month differs from volatility over a longer period – six months or a year – so the best approach is to calculate the volatility over several time periods. Also, sometimes stocks swing widely on a day-to-day basis, but on a week-to-week basis they are not quite as wild. This is called “mean reversion” – the prices gravitate towards a midpoint.
