How to Calculate Beta using Covariance and Variance

This video shows how to calculate the beta of a stock using the covariance of the stock with the market index. Beta is equal to: (1) the covariance of a company's stock returns with the returns of the market index (e.g., the returns of the S&P 500) divided by (2) the variance of the returns of the market index. Covariance / variance = beta For example, if we are examining monthly stock returns for a company called Fluffy Love and the S&P 500 for the past five years, and we find that the covariance between the returns of Fluffy Love and the returns of the S&P 500 is 0.8, while the variance of the returns of the S&P 500 is 0.4, this means that Fluffy Love has a beta of 2.— Edspira is the creation of Michael McLaughlin, an award-winning professor who went from teenage homelessness to a PhD.
