Alpha and Beta

Definition

Alpha and Beta are financial metrics used to evaluate the performance of an investment compared to a benchmark. Alpha measures the excess return generated by an investment relative to its expected return, while Beta assesses the investment's volatility in relation to the market. Understanding these terms is crucial for analyzing the performance of international mutual funds and ETFs, as they help investors gauge risk and return.

1. Alpha is often expressed as a percentage and indicates how much an investment outperformed or underperformed its benchmark.
2. A positive alpha suggests that the investment has performed better than expected based on its risk profile, while a negative alpha indicates underperformance.
3. Beta values greater than 1 imply that the investment is more volatile than the market, whereas values less than 1 suggest lower volatility.
4. International mutual funds may exhibit different alpha and beta characteristics due to currency fluctuations and geopolitical risks.
5. Investors use alpha and beta together to assess an investment's potential for reward against its inherent risks, especially in diverse international markets.

Review Questions

• How do alpha and beta metrics help investors assess the performance of international mutual funds?
  • Alpha provides insight into how well an international mutual fund has performed relative to its expected return based on its risk profile, while beta indicates the fund's volatility compared to the overall market.
