Jensen's Alpha

Definition

Jensen's Alpha is a measure of the excess return that a portfolio or investment generates over the expected return based on its risk level, as determined by the Capital Asset Pricing Model (CAPM). It reflects how well a portfolio manager has performed relative to the market, taking into account the risk taken to achieve those returns. This concept is especially significant for philanthropic funds, as it helps assess the effectiveness of investment strategies and asset management in achieving financial goals while supporting charitable missions.

5 Must Know Facts For Your Next Test

1. Jensen's Alpha is calculated using the formula: $$\alpha = R_p - (R_f + \beta \times (R_m - R_f))$$ where $R_p$ is the portfolio return, $R_f$ is the risk-free rate, $\beta$ is the portfolio's beta, and $R_m$ is the market return.
2. A positive Jensen's Alpha indicates that a portfolio has outperformed its expected return based on its risk level, while a negative alpha suggests underperformance.
3. In philanthropy, measuring Jensen's Alpha helps organizations evaluate whether their investment strategies align with their mission and maximize returns for future funding.
4. Investors often use Jensen's Alpha alongside other performance metrics, like the Sharpe Ratio, to gain a comprehensive view of both return and risk in their portfolios.
5. Jensen's Alpha can help philanthropic funds adjust their investment strategies by highlighting areas of strong or weak performance relative to market expectations.

Sharpe Ratio:

A ratio that measures the performance of an investment compared to a risk-free asset, accounting for its risk; it is calculated by taking the difference between the portfolio return and the risk-free rate and dividing it by the standard deviation of the portfolio return.
