When making trading decisions, one should avoid allowing sunk costs (i.e., costs that have already occurred and cannot be recovered) to influence your judgment or choice. These costs have already been incurred and cannot be changed regardless of future choices, and therefore should not be considered in the decision-making process.
For example, a common mistake in contract trading: holding onto losing positions.
Characteristics of sunk costs:
Irrecoverable: This amount has been consumed and lost, yet you fantasize about breaking even.
Does not affect future earnings: Their existence does not have any actual impact on future decisions.
For instance, if a cryptocurrency has lost 50%, you need a 100% increase to break even; if it has lost 90%, you need a 1000% increase to break even.
Why not include them in decision-making:
Avoid emotional interference: People tend to continue adding resources because they are reluctant to waste, such as thinking “I have already invested so much, I cannot give up,” this mindset may lead to even greater losses.
Focus on future value: Decisions should be based on potential future returns and costs, rather than past investments.
Key principle:
"What determines the future are future costs and benefits, not past sunk costs."
Pay attention to "marginal benefits" — the value brought by additional investments, rather than the resources that have already been lost.
