Alpha is a term used in finance to describe the excess return of an investment relative to the return of a benchmark index. It is a measure of the performance of an investment relative to the market or a specific benchmark. Alpha is often used to evaluate the skill of a portfolio manager or investment strategy in generating returns above what would be expected based on the level of risk taken. A positive alpha indicates that the investment has outperformed the benchmark, while a negative alpha indicates underperformance.
