Calculating the beta of a portfolio.

A beta coefficient for a portfolio of assets measures how that portfolio value changes compared to a benchmark, like the S&P 500. A value of 1 suggests that it fluctuates as much as the index and in the same direction. A beta coefficient of less than 1 suggests a portfolio that fluctuates less than the benchmark.If an asset has a beta above (below) 1, it indicates that its return moves more (less) than 1-to-1 with the return of the market-portfolio, on average. In ...Calculating CAPM Beta. In this paper, we will look at the capital asset pricing model (CAPM), a simple but widely used factor model in finance.

Essentially, beta measures the volatility of a stock relative to the broader market. A beta of 1 indicates that the stock’s price will move in lockstep with the market.CAPM Formula. The calculator uses the following formula to calculate the expected return of a security (or a portfolio): E(R i) = R f + [ E(R m) − R f] × β i. Where: E(R i) is the expected return on the capital asset,. R f is the risk-free rate,. E(R m) is the expected return of the market,. β i is the beta of the security i.. Example: Suppose that the risk-free rate is 3%, …Since the beta coefficient of Microsoft is lesser, it represents that it is a less volatile stock and thus, more investment can be placed in Microsoft and less in Apple Inc.
