Review Questions

• How does Jack Treynor's development of the Treynor Ratio enhance the evaluation of investment performance?
  • Jack Treynor's development of the Treynor Ratio enhances evaluation by focusing on how well an investment performs relative to its market risk, measured through beta. This metric allows investors to see not just raw returns but how much return they are getting per unit of systematic risk taken. It shifts the conversation from absolute performance to risk-adjusted outcomes, making it a valuable tool for comparative analysis among investments.
• Compare and contrast the Treynor Ratio with the Sharpe Ratio in terms of their approach to measuring investment performance.
  • The Treynor Ratio and Sharpe Ratio both measure investment performance but do so differently based on their consideration of risk. The Treynor Ratio uses beta to assess systematic risk, making it suitable for diversified portfolios where only market risk matters. In contrast, the Sharpe Ratio considers total risk by using standard deviation, thus providing a broader view of an investment’s risk-adjusted performance. This difference makes each ratio useful in distinct scenarios depending on an investor's focus.
