What is Beta? Beta (β) is a measure of volatility, or systematic risk, of a security or portfolio in comparison to the market as a whole. (Most people use the S&P 500 Index to represent the market.) Beta is also a measure of the covariance of a stock with the market. It is calculated using regression analysis.
However, It is usually the rate at which the government bonds and securities are available and inflation-adjusted. The following formula shows how to arrive at the risk-free rate of return: Risk Free Rate of Return Formula = (1+ Government Bond Rate)/ (1+Inflation Rate)-1.
