Sunk Cost Fallacy

June 10th, 2023

Making rational decisions based on accurate information and analysis is crucial in the investment world. However, human psychology often influences our decision, leading to cognitive biases that can hinder our performance, one such bias is the sunk cost fallacy. So over the next few minutes im going to help you understand the sunk cost fallacy, explore its impact on investment decisions, and provide some strategies to mitigate its effects.

Understanding Sunk Cost Fallacy

The sunk cost fallacy refers to the irrational behavior of a trader or investor who continues to invest in a failing project or asset due to the time, money and effort already invested, despite it being “a bad bet” or unlikely to turn around any time soon leading to further opportunity cost or out right loss of capital. Unfortunately people tend to let their past investments influence their decision-making, rather than objectively evaluating the future outlook.

The sunk cost fallacy is deeply rooted in human psychology. We tend to try and avoid the feelings of regret or perceiving our past efforts as wasted. We will often attach more value to our sunk cost in a position, which can effect making decisions about the future.

Impact

Investors who fall into this trap might hold on to underperforming assets, hoping to recover their initial investments or turn a profit. They are likely to disregard new information or signals that suggest that it is time to cut their losses, move on and look for the next trade. This behavior can lead to significant financial losses and missed opportunities from other trades known as “opportunity cost”, or even cause frustration and anger ultimately leading to the trader quitting.

Mitigation

  • Awareness: Accept that sunk costs are already gone and should not be factored into your decision. Acknowledge that focusing on potential future gains is more important than past investments.
  • Objective Evaluation: Regularly assess your positions to identify underperforming assets objectively. Have a trade plan with specific criteria for evaluating investments and stick to them. If an investment consistently fails to meet your expectations, it might be time to cut your losses.
  • Independent Perspective: Although I’m not condoning taking people’s advice on investment decisions, often being apart of a solid and experienced community of traders can help add an objective view to an asset or trade idea. Their perspectives can offer valuable insights and help you make rational decisions based on current circumstances.
  • Position Sizing: Understanding how to correctly size a position to avoid over investing, can help to avoid getting into these situations in the first place. Practice good diversification to avoid developing a bias or having a “favorite” that you get attached to.
  • Stop-Losses: Implementing stop-losses can be an effective strategy to limit potential draw down. These orders automatically trigger to close down a position if the asset price falls below a certain pre-determined threshold, protecting you from further losses.

Conclusion

The sunk cost fallacy can create a significant challenge to rational decision-making in the world of trading and investing. It is essential to remain aware of its influence and adopt strategies that prioritize future potential over past performance. Remember, the future always holds greater opportunities than the past; do not let sunk costs cloud your judgment.
