## About Beta Portfolio Calculator (Formula)

Beta is a measure of a stock’s volatility in relation to the overall market. The beta of a portfolio is calculated as the weighted average of the individual betas of the stocks in the portfolio, where the weights are the proportion of each stock’s value in the portfolio. The formula for calculating the beta of a portfolio is:

**Beta = (w1 * Beta1) + (w2 * Beta2) + … + (wn * Beta n)**

Where: w1, w2, …, wn = the weights (proportion of each stock’s value in the portfolio) Beta1, Beta2, …, Beta n = the individual beta of each stock in the portfolio.

It is important to note that a beta of 1 indicates that the stock’s price will move with the market, while a beta less than 1 means it is less volatile than the market, and a beta greater than 1 indicates higher volatility.
