Rule Du Jour: Rule #16: Sunk Cost Fallacy

h/t to MidBandit for reminder

A Crucial Lesson for Investors: The sunk cost fallacy is a cognitive bias that leads investors to make irrational decisions based on past investments of time, money, or effort rather than focusing on current market conditions and future prospects. This fallacy can be particularly dangerous in investing, as it often results in holding onto losing positions for too long or doubling down on failing strategies.

Key Points

• Sunk costs are investments that have already been incurred and cannot be recovered.

• In investing, it's critical to ignore sunk costs and focus on present information and future potential.

• Refusing to sell a losing position solely to avoid realizing a loss is a prime example of the sunk cost fallacy. I covered it yesterday, and last week in the community, many are still clinging to dreams and holding onto losing assets with the hope of getting back to breakeven, and that is a bad idea because breakeven may never happen.

Major Takeaways

• Emotional Detachment: Getting married to any one asset can lead to emotional decision-making, clouding judgment and preventing objective analysis of market conditions.

• Opportunity Cost: Holding onto underperforming assets due to sunk costs prevents investors from allocating capital to potentially more profitable opportunities. So many crypto examples here. NOT ONLY DO YOU LOSE ONCE< BUT YOU LOSE TWICE - OPPTY COST of NOT BEING ON A FASTER HORSE!

• Risk Management: Failing to cut losses because of the sunk cost fallacy can lead to significant portfolio damage, as losing positions may continue to decline.

How to Fix SCF

To avoid falling victim to the sunk cost fallacy, investors should:

• Regularly review their positions based on current market conditions and future prospects. I do what I call "Cleaning Shop" at the end of every year - take profits, kill losers etc.

• Implement strict pain levels of when to get out. Know your exit before you enter to both the upside and downside.

• Develop and adhere to a well-defined trading plan that includes exit strategies.

To win at this game, you need to make rational decisions. Otherwise, the market will rip your face off. Respect it.
