Expert Solution
Step 1

Beta helps in measuring the systematic risk of a security or portfolio compared to the market as a whole. Beta is used in the capital asset pricing model (CAPM) which helps in describing the relationship between systematic risk and expected return for the assets usually stocks. The stocks with betas higher than 1.0 tend to be more volatile than the S&P 500 which has a beta of 1.
