AXA Rosenberg risk model disclaimer
The firm seeks to achieve its clients’ investment objectives primarily through reliance on the modelling of proprietary and 3rd party financial and non-financial data, information, and considerations, the sources, weights, and implementation of which may be subject to change and/or the discretion of the firm regardless of whether described herein or elsewhere. Although many of its investment approaches are driven by bottom-up stock selection akin to that of a traditional fundamental investor, the firm seeks to achieve its clients’ investment objectives primarily in reliance on analytical models. The goal of the firm’s systematic approach is not to replicate a perfect “model” portfolio; instead, like other long-term, fundamentally oriented investors, it seeks to create portfolios possessing ex ante those fundamental and statistically important characteristics reflecting our investment beliefs. The firm’s ability to implement its investment objectives depends on various considerations such as the models’ economic, analytical and mathematical underpinnings, the accurate encapsulation of those principles in a complex computational (including software code) environment, the quality of the models’ data inputs, changes in market conditions, and the successful expression of the models' views into the investment portfolio construction process. Many of these have subjective elements that present the possibility of human error. While the investment process principally relies on models, the firm’s process also incorporates the investment judgment of its portfolio managers who may exercise discretion in attempting to capture the intent of the models, particularly in changing market conditions. The firm’s success in implementing its investment objectives may depend on the ability of portfolio managers and others to interpret and implement the signals generated by the models. The firm has established certain systematic rules and processes for monitoring client portfolios to ensure that they are managed in accordance with their investment objectives, but there is no guarantee that these rules or processes will effectively manage the risks associated with its investment process under all market conditions. While the firm employs controls designed to assure that our models are sound in their development and appropriately adapted, calibrated and configured, analytical error, software development errors, and implementation errors are an inherent risk of complex analytical models and quantitative investment management processes. These errors may be extremely hard to detect, and some may go undetected for long periods of time or indefinitely. The firm’s controls, including our escalation policies, are designed to ensure that certain types of errors are subject to review once discovered. However, the effect of errors on our investment process and, where relevant, performance (which can be either positive or negative) may not be fully apparent even when discovered. When the firm discovers an investment process error in one of its models, it may in good faith and in accordance with its obligations, decide not to correct the error, to delay correction of an error, or develop other methodology to address the error, if not inconsistent with the client’s interests. Also, the firm generally will not disclose to affected clients investment process errors that are not the result of a contractual or regulatory breach, or that are non-compensable, unless it otherwise determines that information regarding the error is material to its clients.
