Vistra  (MEX:VST) Beta Explanation

Beta is a measure of the volatility, or systematic risk, of a security or a portfolio in comparison to the market as a whole. We usually compare beta to 1. A beta of 1 indicates that the security's price will move with the market. A beta of less than 1 means that the security will be less volatile than the market. A beta of greater than 1 indicates that the security's price will be more volatile than the market.

Cost of Equity = Risk-Free Rate of Return + Beta of Asset * (Expected Return of the Market - Risk-Free Rate of Return)
