Episil Technologies (ROCO:3707) 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.
Beta is primarily used in the Capital Asset Pricing Model (CAPM) to calculate the Cost of Equity, which can be used in the calculation of WACC %. The formula of Cost of Equity is:
Cost of Equity = Risk-Free Rate of Return + Beta of Asset * (Expected Return of the Market - Risk-Free Rate of Return)
