21 May 2015 In layman terms, academic finance defines beta as a measure of a stock's volatility in relation to the overall market and/or a benchmark. 8 Jul 2016 Stock beta is used by investors to examine the risk-return estimation period increases - the estimate of beta improves in terms of precision.

To determine the beta of an entire portfolio of stocks, you can follow these four steps: Add up the value (number of shares x share price) of each stock you own and your entire portfolio. Based on these values, determine how much you have of each stock as a percentage Multiply those percentage Beta is a measure of how sensitive a firm's stock price is to an index or benchmark. A beta greater than 1 indicates that the firm's stock price is more volatile than the market, and a beta less To calculate the Beta of a stock or portfolio, divide the covariance of the excess asset returns and excess market returns by the variance of the excess market returns over the risk-free rate of return: Advantages of using Beta Coefficient One of the most popular uses of Beta is to estimate the cost of equity (Re) in valuation models. Beta is a measure of a particular stock's relative risk to the broader stock market. Beta looks at the correlation in price movement between the stock and the S&P 500 index. Beta can be calculated using Excel in order to determine the riskiness of stock on your own. The formula for calculating beta is the covariance of the return of an asset with the return of the benchmark divided by the variance of the return of the benchmark over a certain period. In financial/investment terminology, beta is a measurement of volatility or risk. Expressed as a numeral, it shows how the variance of an asset – anything from an individual security to an entire portfolio – relates to the covariance of that asset and the stock market (or whatever benchmark is being used) as a whole. Beta is a measure of a stock's volatility in relation to the market. By definition, the market has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market. A stock that swings more than the market over time has a beta above 1.0. If a stock moves less than the market,
