Jensen’s measure, Jensen’s alpha, capital asset pricing model. Developed by American economist Michael Jensen in 1968, the model is used to monitor the performance of mutual fund managers on a risk-adjusted basis. Jensen's Alpha is also known as the Jensen's Performance Index. It was first used in the 1970s by Michael Jensen to evaluate the performance of fund managers. Specifically, it is measuring the difference between the actual returns of a portfolio during a period and the expected returns of the portfolio using the Capital Asset Pricing Model (CAPM). Jensen's alpha is used to determine the abnormal return of a security or portfolio of securities over the theoretical expected return.

Alpha is also known as Jensen Index. It is important to understand the concept of alpha formula because it is used to measure the risk-adjusted performance of a portfolio. It is also recognized as the excess return or the abnormal rate of return of a portfolio. The Jensen’s Alpha is a popular risk-adjusted performance measure used by portfolio managers to determine how much excess returns their portfolio has generated over and above the market returns as suggested by the CAPM model. A positive alpha indicates that the portfolio has outperformed the market, and vice versa. Alpha or Jensen Index (invented my Michael Jensen in the 1970s) is an index that is used in some financial models such as the capital asset pricing model (CAPM) to determine the highest possible return on an investment for the least amount of risk. In other words, Alpha measures how well an investment performed compared to its benchmark.

Sharpe ratio. The Sharpe ratio (aka Jensen in 1968 and known as a measure that represents the average return on an asset predicted by the Capital Asset Pricing Model (CAPM), given the portfolio's El Alfa de Jensen (o Alpha de Jensen) es un ratio que mide la habilidad de un gestor de carteras de inversión por obtener rentabilidades por encima del índice The Jensen's alpha, also known as Jensen's Performance Index or ex-post alpha , is used to determine the abnormal return of a security or portfolio of securities
The Jensen's alpha is the intercept of the regression equation in the Capital Asset Pricing Model and is in effect the exess return adjusted for systematic risk.
In finance, Jensen's alpha (or Jensen's Performance Index, ex-post alpha) is used to determine the abnormal return of a security or portfolio of securities over the theoretical expected return. It is a version of the standard alpha based on a theoretical performance index instead of a market index. Using these variables, the formula for Jensen's alpha is: Alpha = R(i) - (R(f) + B x (R(m) - R(f))) For example, assume a mutual fund realized a return of 15% last year. The appropriate market index for this fund returned 12%. The beta of the fund versus that same index is 1.2, and the risk-free rate is 3%.
