In discussions regarding investment strategies and risk management, responses from managers and allocators converge into three primary categories when addressing previous failures and lessons learned.
A robust response occurs when a manager identifies a specific drawdown and articulates the structural assumption that was proven incorrect. In these cases, they differentiate between adjustments to model settings—such as lookback windows or position sizes—and modifications to foundational assumptions, which may involve rethinking how signals interact or how conflicting information is evaluated. This type of answer also includes a rationale for why the same type of failure is less likely to happen again, linking the lesson learned to broader model assumptions about market behavior.
Conversely, a standard response tends to focus on superficial changes like adjusting settings without delving into whether the underlying logic of the model was altered. Engaging in follow-up questions can reveal whether deeper issues were acknowledged, with managers capable of candid reflections standing out from those who may rely on vague language about structural changes.
The concerning response comes in three forms: an inability to recall any significant past failures, an external attribution of all struggles to market conditions without introspection, or a defense of the model’s accuracy despite evident shortcomings. Managers who fail to recognize any structural assumptions that may have been flawed either lack a logical framework for their models or have opted not to scrutinize them.
Why this story matters
- Understanding how investment managers respond to failures can reveal their critical thinking and adaptability.
Key takeaway
- Effective risk management goes beyond surface-level adjustments; innovation often requires reevaluating foundational models.
Opposing viewpoint
- Some may argue that external factors can overshadow even the most sound investment strategies, making it unfair to evaluate model assumptions in isolation.
