Performance & Backtesting Policy
How MCH classifies performance outputs and the disclosures that accompany backtests, simulations and forecasts.
This policy governs how MCH Publications classifies and discloses performance information: model returns, simulation portfolios, historical alpha, backtests, portfolio comparisons, return forecasts and options scenario payoffs. It forms part of the MCH Publications policy framework and is one of the research-governance standards, alongside the Research Integrity Policy.
Scope
This policy applies to every page and publication that shows:
- model returns
- simulation portfolios
- historical alpha
- backtests
- portfolio comparisons
- return forecasts
- options scenario payoffs
Required classifications
Every performance output should be classified as one of:
- actual/live
- audited actual
- hypothetical
- simulated
- backtested
- paper
- forecast/expected
Different classifications must not be merged into one apparent historical-performance series without clear disclosure.
Backtest disclosures
Backtests are hypothetical unless explicitly identified otherwise. Where relevant, a backtest should disclose its assumptions, including:
- starting universe
- delisting treatment
- survivorship controls
- data availability
- point-in-time treatment
- rebalance date
- transaction costs
- slippage
- liquidity assumptions
- taxes
- dividends
- corporate actions
- execution assumptions
- leverage
- shorting costs
- options pricing assumptions
Expected returns
Expected returns, target prices and probability-weighted outcomes must be described as estimates, not as realised performance.
Historical returns
Historical model or simulation results must not be labelled in a manner that suggests they are returns actually earned by clients or by MCH, unless that is demonstrably true.
Charts
Every performance chart should carry a concise classification label near the chart, not only in a distant footer. Examples:
- BACKTEST — hypothetical, not actual investment performance
- SIMULATED PORTFOLIO — transaction costs and other assumptions apply
