Excess Return Calculator

Excess return, also known as alpha, measures the return of an investment relative to the return of a benchmark index or risk-free rate. It is used to evaluate the performance of a portfolio manager or investment strategy.

Historical Background

Excess return has been a critical concept in finance for evaluating the skill of portfolio managers and the effectiveness of investment strategies. It became particularly prominent with the development of the Capital Asset Pricing Model (CAPM), which introduced the idea of comparing portfolio returns to a risk-adjusted benchmark.

Calculation Formula

The formula to calculate excess return is:

\[ \text{Excess Return} = \text{Portfolio Return} - \text{Benchmark Return} \]

Example Calculation

If your portfolio return is 10% and the benchmark return is 7%, the calculation would be:

\[ \text{Excess Return} = 10\% - 7\% = 3\% \]

Importance and Usage Scenarios

Understanding excess return is vital for investors and portfolio managers as it helps assess the value added by active management. A positive excess return indicates that the portfolio has outperformed the benchmark, while a negative excess return suggests underperformance.
