In this episode you will learn: - Standard deviation measures an investment's total risk, which is the combination of systematic and unsystematic risk. - Beta is a narrower metric that measures only the systematic, or market, risk of an investment relative to a benchmark like the S&P 500. - Alpha represents the excess return an investment earns above its expected return, given its beta, serving as a measure of manager performance. - R-squared indicates how much of a portfolio's movement is explained by its benchmark, and a high R-squared is necessary for alpha and beta to be considered reliable statistics. - A common Series 65 exam trap involves a security with a high alpha but a low R-squared, which implies the alpha is not a meaningful indicator of performance.
