When Investment Conviction Becomes a Cognitive Trap for Investors
Imagine you have a limited amount of brain energy every day.
If you use it all up making lots of decisions, your brain gets tired, like a phone battery running low.
This tiredness is called cognitive depletion, and it can make you act without thinking clearly.
When your brain is tired, you make worse choices, like buying things you do not need or picking a weak password.
The article explains how this affects grown-ups who invest money in stocks.
When a stock they bought goes down, they often refuse to sell it because selling feels like admitting they were wrong.
People also feel losses more painfully than gains and value things they already own too much.
The author advises making a plan for exits, setting stop-loss limits, and keeping the brain strong with sleep, exercise, and meditation.
Learning to quit at the right time is a good skill, not a failure!
The article argues that investors often hesitate to exit positions even when their initial premise is wrong, accumulating losses in the process.
Cognitive depletion is described as mental exhaustion from prolonged focus, stress, or making too many choices, leading to low concentration and impulsive decision-making.
A 2016 Newcastle University study found that cognitive depletion diminishes people's capacity to choose strong passwords.
Loss aversion, the sunk cost fallacy, and the endowment effect are cited as reasons investors hold losing positions well past the point of value addition.
The author recommends structuring the investing process with defined stop-loss levels, documented feedback loops, and routines such as good sleep, exercise, and meditation.
