Jensen index of portfolio performance
Jensen’s Alpha, also known as the Jensen’s Performance Index, is a measure of the excess returns earned by the portfolio compared to returns suggested by the CAPM model. It represents by the symbol α. The value of the excess return may be positive, negative, or zero. 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). While measuring return performance, Jensen’s alpha measure takes an investment’s risk profile into account and so gives an overall picture of a portfolio or stock’s performance on a risk-adjusted basis. This helps investors to gauge the value which a fund manager adds or detracts from a portfolio, and helps in the comparison of funds. 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. In this respect, this paper looks at the methods that are most widely used, both in theory and in practice, to measure portfolio performance: Sharpe index, Treynor index and Jensen’s alpha or index.
