IMPORTANT: The backtested performance data and validation studies presented by ERS are subject to the limitations and disclosures described below.
Backtested performance is hypothetical and does not reflect actual trading. The performance figures presented in our validation studies, including the 25-year FSN™ study and other rating validations, represent what would have occurred if specific strategies had been implemented during the historical period examined.
Backtested results have inherent limitations:
Past performance, whether actual or backtested, is not indicative of future results. The following limitations apply to all backtested performance data:
Backtested returns generally do not reflect the deduction of transaction costs, management fees, or other expenses that would reduce actual returns. Actual trading would incur brokerage commissions, bid-ask spreads, market impact costs, and other expenses.
Backtested strategies are evaluated using historical market conditions that may not recur. Future market conditions, including volatility, liquidity, and correlation patterns, may differ materially from historical periods.
While we have taken steps to eliminate look-ahead bias, certain aspects of our methodology were developed with knowledge of historical data. The strategies were not implemented in real-time during the backtested periods.
Historical financial data may contain errors, omissions, or subsequent revisions that were not available at the time of the original reporting. We rely on third-party data providers for historical financial statements and pricing data.
Our rating methodologies have been refined over time. The backtested results assume consistent application of current methodology across historical periods, which may differ from how decisions would have been made in real-time.
Our model portfolios have been tracked live since their inception dates. Live performance is verified by independent third parties including BX Partners and IndexOne. Live performance reflects actual implementation and is subject to different considerations than backtested data.
ERS welcomes independent verification of our validation studies. We invite interested parties to submit any 2 of our 9 proprietary ratings to McKinsey, PwC, Deloitte, or another qualified firm for independent audit. Contact us for more information about our audit process.
References to expected future performance or the potential benefits of our ratings constitute forward-looking statements. These statements involve risks and uncertainties that could cause actual results to differ materially. We make no guarantees regarding future performance.
