## Beta of stock formula cfa

A stock's beta coefficient is a measure of its volatility over time compared to a market benchmark. A beta of 1 means that a stock's volatility matches up exactly with the markets. I know to calculate beta the formula is : Covariance / Market Variance. however, I came across this: to work out portfolio A's beta coefficient: E(ra) - rf / E(rm) - rf. Why does this calculation of beta differ from the initial one and when should I use each one? Any help is much appreciated.

## Below is the formula to calculate stock Beta. Stock Beta Formula = COV(Rs,RM) / VAR(Rm) Here, Rs refers to the returns of the stock. Rm refers to the returns of the market as a whole or the underlying benchmark used for comparison. Cov(Rs, Rm) refers to the covariance of the stock and market.

Beta is Calculated using below formula. Beta = Return on risk taken on stocks/ Return on risk taken on Market; Beta = 5 /7; Beta = 0.71; So, value for beta is 0.71 which company is less volatile than the market. Calculation of Beta for the stock profile. Now, let us see a calculation of Beta for the stock profile. Calculate Stock’s Beta using one of the two methods. Method 1 – Calculate Beta using the formula. Method 2 – Calculate Beta using excel’s slope function. Beta = SLOPE(range of % change of equity, range of % change of index). A stock whose returns vary less than the market's returns has a beta with an absolute value less than 1.0. A stock with a beta of 2 has returns that change, on average, by twice the magnitude of the overall market; when the market's return falls or rises by 3%, the stock's return will fall or rise (respectively) by 6% on average. Beta coefficient is a measure of sensitivity of a company's stock price to movement in the broad market index. It is an indicator of a stock's systematic risk which is the undiversifiable risk inherent in the whole financial system. Beta coefficient is an important input in the capital asset pricing model (CAPM). How to Calculate the Beta Coefficient for a Single Stock. The beta coefficient is a metric used to measure the difference between the average market return and the return on an individual stock or portfolio of stocks. The beta of the market equals one, so portfolio or stock betas close to one will emulate the A stock's beta coefficient is a measure of its volatility over time compared to a market benchmark. A beta of 1 means that a stock's volatility matches up exactly with the markets.

CFA Level 1 Exam Takeaways for Asset Beta and Equity Beta in the Context of Pure-Play Method. The asset beta (unlevered beta) is the beta of a company on the assumption that the company uses only equity financing. The equity beta (levered beta, project beta) takes into account different levels of the company's debt. A higher beta indicates that the stock is riskier and a lower beta indicates that the stock is less volatile as compared to the market. Mostly Betas generally fall between the values of range 1.0 to 2.0. The beta of a stock or fund is always compared to the market/benchmark. The beta of the market is equal to 1. Steps in the Pure-play Method for Calculating Beta. Step 1: A comparable company is selected. Step 2: The equity beta of the comparable company, B L,comparable is estimated. Step 3: The comparable company’s beta is then unlevered by removing the effects of its financial leverage and leaving its business risk. The stock betas of the three firms are taken and found to be 2.73, 2.23, and 1.73 respectively. The ratio of debt to equity for the three firms averages to 0.67. The marginal tax rate is 36%. The average stock β works out to 2.23. Beta is Calculated using below formula. Beta = Return on risk taken on stocks/ Return on risk taken on Market; Beta = 5 /7; Beta = 0.71; So, value for beta is 0.71 which company is less volatile than the market.

### In finance, the capital asset pricing model (CAPM) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio. Contents. 1 Overview; 2 Inventors; 3 Formula; 4 Modified Betas; 5 Security market line CFA Institute Conference Proceedings Quarterly.

The average stock β works out to 2.23. Translating these numbers into the formula for unlevered firms, we get: β U = β L / (1 + (1 - T)(D/E)) = 2.23/(1+0.64 x 0.67) = 1.56. This suggests that on an all-equity basis the β of the project would be 1.56.

## beta’s are apparently stationary over the long-term, so there is mean reversion to 1, so while historical betas use past regressions to estimate beta, forward looking beta includes the (1/3)*1 to account for future mean reversion of beta to 1. Remember that betas in a portfolio are the weighted average of each beta.

A positive beta indicates the asset moves in the same direction as the market, whereas a negative beta would indicate the opposite. The beta of a risk-free asset is zero because the covariance of the risk-free asset and the market is zero. The beta of the market is by definition 1 and most developed market stocks tend to exhibit high, positive betas. Below is the formula to calculate stock Beta. Stock Beta Formula = COV(Rs,RM) / VAR(Rm) Here, Rs refers to the returns of the stock. Rm refers to the returns of the market as a whole or the underlying benchmark used for comparison.
