This document discusses the importance of selecting an appropriate benchmark for evaluating investment performance. It explains that benchmarks should reflect the portfolio's strategy, asset allocation, and investment options. For multi-asset portfolios, the benchmark is typically constructed by combining various market indices weighted to represent the portfolio. Static benchmarks keep index weights constant to assess asset allocation decisions, while dynamic benchmarks adjust weights to evaluate individual managers. In summary, selecting the right benchmark is key to understanding what a portfolio's performance is communicating about the manager's investment decisions.
