Performance Attribution

Definition

Performance attribution is a method used to evaluate the performance of an investment portfolio by breaking down its returns into components that explain how and why those returns were achieved. This analysis helps investors understand the contributions of individual assets and investment decisions, allowing them to assess the effectiveness of their investment strategies and identify areas for improvement.

Review Questions

• How does performance attribution enhance an investor's understanding of their portfolio's returns?
  • Performance attribution enhances an investor's understanding by breaking down overall portfolio returns into specific components. This process identifies which investments contributed positively or negatively to the overall performance. By analyzing these contributions, investors can discern whether returns were driven by strategic asset allocation or effective security selection, providing insights into what worked well and what didn't.
• Discuss the significance of both allocation effect and selection effect in the context of performance attribution.
  • The allocation effect in performance attribution reflects how effective a manager's asset allocation decisions were in contributing to overall portfolio returns. In contrast, the selection effect assesses the impact of individual security choices compared to their benchmarks. Understanding both effects allows investors to differentiate between successful investment strategies based on asset class allocation versus those based on stock picking skills, providing a clearer picture of a manager's effectiveness.
• Evaluate how effective performance attribution can influence future investment strategies for portfolio managers.
  • Effective performance attribution provides valuable feedback for portfolio managers by highlighting successful and unsuccessful aspects of their investment strategies. By analyzing past performances through attribution analysis, managers can identify patterns and adjust their approaches accordingly. This evaluation allows them to refine their asset allocation and security selection processes, potentially leading to better future performance as they learn from both successes and shortcomings.
