Calculate beta of a portfolio.

Investors often calculate beta by comparing a stock’s price changes to the movements of a benchmark index, such as the S&P 500, throughout a 12-month period. We’ll discuss calculating beta yourself in a bit. But first let’s understand why it matters, since you can use plenty of free online tools and calculators to compute it yourself.How to Calculate Beta β. To calculate Beta, you must use the formula: Beta = Variance of an Equity’s Return / Covariance of the Stock Index’s Return. To put it another way, Beta compares the volatility of a stock (or a portfolio) to the volatility of a benchmark index like the S&P 500. If a stock has a beta greater than 1, that means the ...Interpret beta and calculate the beta of a single asset or portfolio. Calculate, compare, and interpret the following performance measures: the Sharpe performance index, the Treynor performance index, the Jensen performance index, the tracking error, information ratio, and the Sortino ratio.

The formula for calculating the beta of a portfolio is: Beta = (w1 * Beta1) + (w2 * Beta2) + … + (wn * Beta n) Where: w1, w2, …, wn = the weights (proportion of each stock’s value in the portfolio) Beta1, Beta2, …, Beta n = the individual beta of each stock in the portfolio.Portfolio Volatility = (Variance (aS 1 + bS 2 + cS 3 + … xS n )) 1/2. Where: n = number of stocks in the portfolio. a, b, c, … x are the portfolio weights of stocks S 1, S 2, S 3 …S n. S = stock’s return. The formula takes the variance of each stock’s return in the portfolio and then expresses it as a standard deviation by taking the ...

Key Takeaways. Both alpha and beta are historical measures of past performances. Alpha shows how well (or badly) a stock has performed in comparison to a benchmark index. Beta indicates how ...We find a beta of 1.30 which gives us an expected return of 10.10%. Investment Analysis As shown by the comparison of these two stocks, there is a pretty big difference between 4.36% and 10.10%.

There are two methods available to measure a stock’s beta. Both are expected to result in the same numerical outcome. Beta = Covariance / Variance: Where covariance is the stock’s return relative to the market's return. Variance shows how the stock moves in relation to the market.There are two ways the SIM can be expressed, either in " raw returns " (aka ordinary returns) or in " excess returns ." The SIM formula expressed in raw returns is shown below: R i = α i + β i R m + ε i. where: R it = total return of a stock or portfolio i. β i = investment beta. R m = market portfolio return.The formula for calculating the beta of a portfolio is: Beta = (w1 * Beta1) + (w2 * Beta2) + … + (wn * Beta n) Where: w1, w2, …, wn = the weights (proportion of each stock’s value …Imagine that you had a stock which was exactly the same as a short position in another stock (realistically would probably be an ETF, but doesn't matter for argument's sake). This new stock should have exactly the opposite beta as the original stock in question since B = Cov (r,rm)/Var (rm). The only thing to change in that equation is r ...

Then, calculate the beta of the portfolio using a weighted average of all the securities. The portfolio beta is denoted by β. Step 4: Next, calculate the expected rate of return by using risk-free rate (step 1), market risk premium (step 2) and portfolio beta (step 3) as shown below.

However, if you have no portfolio to start with, unsystematic risk is more relevant to you. In this case, standard deviation is your friend because it accounts for both risk types. Beta is volatility in relation to a benchmark whereas Standard Deviation is volatility in relation to actual returns vs expected returns.

Investors use both the alpha and beta ratios to calculate, compare, and predict investment returns. Both ratios use benchmark indexes such as the S&P 500 to compare against specific securities or portfolios. Alpha is the risk-adjusted measure of how a security performs in comparison to the overall market average return.In contrast, if the market return decrease by 10%, the return of the portfolio of beta +1.00 would also decrease by 10%. From the calculation above, portfolio A has a greater than 1.00 beta. This means that portfolio A is a high risk and high return portfolio. Conversely, portfolio B has a beta of less than 1.00.

So now we know how to calculate Beta for a stock. Portfolio betas are found by multiplying the portfolio weight of a particular asset by its Beta and adding them together. So if I have 50% of my money in asset A with a Beta of 1.2 and 50% in asset B with a Beta of 0.9, then my portfolio 𝛃 is = (0.5 x 1.2) + (0.5 x 0.9) = 1.05.Oct 31, 2023 · 1.
