When making trading decisions, one should avoid letting costs that have already occurred and cannot be recovered (i.e., sunk costs) affect your judgment or choices. These costs have already been incurred and cannot be changed regardless of future choices, so they should no longer be included in the weighing 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.
No impact on future returns: Their existence does not have any actual impact on future decisions.
For instance, a cryptocurrency that has lost 50% requires a 100% increase to break even, while a cryptocurrency that has lost 90% requires a 1000% increase to break even.
Why not include them in decision-making:
Avoid interference from emotional factors: People often tend to continue to add resources because they are reluctant to waste, such as thinking, 'I've already invested so much, I can't give up.' This mindset can lead to even greater losses.
Focus on future value: Decisions should be based on potential future gains and costs, rather than past investments.
Key principle:
'The costs and benefits that determine the future are the future costs and benefits, not past sunk costs.'
Focus on 'marginal benefits'—the value brought by additional investments, rather than lost resources.
