Unleashing Alpha: Demystifying Jensen's Formula for Superior Returns

Jensen's alpha, also known as the Jensen index or Jensen's performance measure, is a financial metric used to assess the risk-adjusted performance of an investment or portfolio. It was developed by Michael Jensen, an economist, and Nobel laureate. Jensen's alpha compares the actual return on an investment or portfolio to the expected return based on its level of systematic risk, as measured by the capital asset pricing model (CAPM). The CAPM predicts the expected return of an investment based on its beta, which is a measure of its sensitivity to systematic risk compared to the overall market. The formula for Jensen's alpha is as follows: Jensen's alpha = Actual Return - (Risk-free Rate + Beta × (Market Return - Risk-free Rate)) In this formula, the actual return represents the realized return on the investment or portfolio, the risk-free rate is the return on a risk-free investment such as government bonds, beta measures the systematic risk of the investment or port...
