Performance Attribution

Definition

Performance attribution is the process of breaking down the returns of an investment portfolio to understand the sources of its performance. It connects the dots between overall portfolio performance and the specific decisions made, such as asset allocation and security selection. By analyzing these factors, investors can determine which strategies worked well and which did not, providing insights for future investment decisions.

1. Performance attribution can be divided into two main categories: allocation effect and selection effect. The allocation effect measures how well an investor has done in choosing different asset classes, while the selection effect evaluates the performance of individual securities within those classes.
2. This process is essential for active managers who need to justify their investment decisions and demonstrate their value relative to passive investment strategies.
3. The methodology behind performance attribution often involves comparing the actual portfolio returns with those of a benchmark, highlighting areas where the portfolio has outperformed or underperformed.
4. In addition to helping assess past performance, performance attribution can also serve as a tool for future investment strategy development by identifying strengths and weaknesses in decision-making.
5. Many investors use sophisticated software and models to perform detailed performance attribution analysis, allowing them to analyze large sets of data efficiently.
