What does Jensen's Alpha measure in finance?

• A. The excess return of a portfolio compared to the market
• B. The volatility of an asset over time
• C. The correlation between two financial instruments
• D. The likelihood of defaults in a security portfolio

Answer: (A)

Jensen's Alpha is a key performance metric used in finance to gauge the excess return of an investment relative to the return expected based on its risk level, measured by the Capital Asset Pricing Model (CAPM). Specifically, it quantifies how much more (or less) a portfolio or investment has returned compared to what would have been anticipated based on its systematic risk, represented by its beta. When an investment has a positive Jensen's Alpha, this indicates that it has outperformed the market after accounting for the risk taken, signifying that the portfolio manager has added value. Conversely, a negative Jensen's Alpha suggests underperformance relative to the market’s expectations. This characteristic makes Jensen's Alpha particularly valuable for investors looking to evaluate the performance of asset managers or individual portfolios against a benchmark that reflects the risks involved. The measure captures both return and risk, emphasizing the efficiency of the investment strategy employed. In this context, it aligns perfectly with the definition of excess return, confirming the appropriateness of the chosen answer.
