Return Measurement and Attribution

Portfolio-return methods, benchmark selection, and attribution concepts used to calculate and explain investment performance.

Return measurement establishes what a portfolio earned; attribution examines why it differed from a benchmark or policy allocation. The result depends on valuation dates, external cash flows, income, currency, fees, taxes, and whether the return is historical or hypothetical.

Use Return Calculation Methods to distinguish basic return, return on investment, time-weighted return, money-weighted return, and Modified Dietz. Use Performance Attribution, Benchmarks, and Capture to choose comparison portfolios and interpret allocation, selection, and market-condition effects.

Return figures should not be compared until their period, cash-flow treatment, benchmark, currency, and gross- or net-of-fee basis are aligned.
