Performance Reporting — Reporting & Communication
Core Concepts
Return Reporting
Accurate and consistent return calculation is the foundation of all performance reporting.
Period returns: Report standard time periods — MTD (month-to-date), QTD (quarter-to-date), YTD (year-to-date), 1Y, 3Y, 5Y, 10Y, and since inception. Always state the exact inception date.
Cumulative vs annualized: Annualize returns only for periods greater than 1 year. Annualizing a 3-month return is misleading because it implies the rate is sustainable for a full year. For periods under 1 year, report cumulative (total) returns only.
- Annualized return formula:
(1 + cumulative_return)^(1/years) - 1 - For multi-year periods, always present both cumulative and annualized figures so the reader can see total wealth growth and the rate of compounding.
Gross vs net of fees: Always specify whether returns are gross or net of management fees, advisory fees, and transaction costs. Net-of-fee returns are what the investor actually experiences and should be the primary presentation. If showing gross returns, also show the fee drag.
GIPS (Global Investment Performance Standards): For institutional reporting, follow GIPS requirements — composite construction, full disclosure, verified calculations, and standardized presentation. Even for non-GIPS reports, the principles of fair representation and full disclosure apply.
