What is the Beta Stock Calculator & How does it work?
Beta is a measure of a stock’s volatility in relation to the overall market. A beta value of 1 indicates that the stock’s price will move with the market. A beta greater than 1 means the stock is more volatile than the market, while a beta less than 1 indicates it’s less volatile.
beta = frac{Cov(R_m, R_s)}{Var(R_m)}
beta = Beta
Cov(R_m, R_s) = Covariance between market returns and stock returns
Var(R_m) = Variance of market returns
To calculate beta, you need historical data on the stock’s returns and the market’s returns. The covariance between these two sets of returns is divided by the variance of the market returns.
