How We Manage Bias in Our Investment Process
A structured process for objective decisions
Reducing the impact of bias on financial decisions has been shown to improve the reliability of decisions and the repeatability of investment performance. That is why we not only encourage clients to adopt strategic habits, but also work deliberately to guard against bias within our own investment practice.
The 4 tools we use to manage bias
1. Quantitative Security Selection
We manage each mandate using quantitative security selection and tactical rebalancing. Each security must meet defined criteria and align with the portfolio’s role in the mandate, helping to keep decisions evidence-based rather than reactive.
2. Procedure Flow-Charts for Buy/Sell Discipline
After a security passes our selection criteria, it still must follow a documented procedure flow-chart before we invest.
Similarly, when a security is no longer suitable for the mandate, we sell it—regardless of the current price—avoiding emotional attachment or anchoring.
3. Investment diary and decision logs
We maintain a rigorous investment plan and diary of trade decisions. This log allows us to:
- Record the rationale behind each decision
- Recall the strategy over the security’s time horizon
- Evaluate outcomes honestly and avoid hindsight bias
4. Client documentation and Investment Policy Statements (IPS)
From a client perspective, we collect and maintain thorough notes and scheduled activities to stay aligned with each client’s needs and objectives.
For every client, we develop a customized Investment Policy Statement (IPS).
Your IPS sets:
- The framework for managing your portfolio
- Strategic asset allocation
- Investment strategy
- Key parameters that must remain aligned with your investment objectives and risk profile
