Calculation of beta of a stock
To calculate the beta coefficient for a single stock, you'll need the stock's closing price each day for a given period of time, the closing level of a market benchmark -- typically the S&P 500 -- over the same time period, and you'll need a spreadsheet program to do the statistics work for you. How to calculate beta. The beta of a stock is a measure of its price volatility in comparison to the volatility of the market. If beta equals 1, then its variability is exactly the same as that of the market as a whole. If the beta is higher than 1, then the price of a stock is more volatile than the market level. 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 calculated for stock and for a stock portfolio value of each stock Beta is added up according to their weights to create the portfolio beta. The formula for same is as follows:- The beta of Portfolio = Weight of Stock * Beta of Stock + Weight of Stock * Beta of Stock…so on
Beta values range from 0 to 1, with a value of 1 indicating the highest degree of correlation between the stock and the benchmark. R-Squared is measure that reflects the reliability of a given Beta figure, and should be included in every calculation of a stock's Beta.
Thus, we first estimate the beta of each individual stock in our database for each year as described in Section 3.2.

A stock with a high beta indicates it's more volatile than You can compute beta values of stocks yourself using a statistical formula and details about the price of the stock and the benchmark, or you can use an online arkowitz1 (1952) began modern portfolio theory (MPT) which can be used to explain the relationship between risk and return for assets, particularly stocks.

The risk free interest rate (Rf) is the interest rate the investor would expect to receive from a risk free investment. 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. The beta of Portfolio = Weight of Stock * Beta of Stock + Weight of Stock * Beta of Stock…so on Beta of Portfolio = (0.40*1.20) + (0.60*1.50) Beta of Portfolio = 0.48 + 0.9 Calculating the volatility, or beta, of your stock portfolio is probably easier than you think. A beta of 1 means that a portfolio's volatility matches up exactly with the markets. A higher beta indicates great volatility, and a lower beta indicates less volatility.
The following formula is used for calculating the value of Beta. Beta = Covariance (Rate of Return of Stock, Rate of Return of Market) / Variance of Market It is the slope coefficient obtained through regression analysis of the stock return against the market return.
