Loss Aversion — Definition and Impact on Finances

Definition

Loss aversion is a psychological phenomenon where the pain from a loss is felt approximately twice as strongly as the pleasure from an equivalent gain. Losing 1,000 PLN hurts more than gaining 1,000 PLN feels good.

The concept was introduced by Daniel Kahneman and Amos Tversky as part of prospect theory (1979).

How does this affect investing?

Holding losing positions too long

You don't want to "realize the loss," so you hold falling stocks, hoping for a recovery. Meanwhile, the money could be working in a better investment.

Selling winning positions too quickly

Stock grew 20%? You sell because you're afraid of losing the profit. Meanwhile, it could have grown another 100%.

Avoiding investing altogether

Fear of loss causes money to sit in savings accounts with interest rates below inflation. "At least I won't lose" — but inflation eats your savings.

Disposition effect

Combination of the above: you sell winners too early and hold losers too long. This is exactly the opposite of a rational strategy.

Loss aversion in everyday finances

• Subscriptions — you don't cancel Netflix because you'd "lose" access, even though you haven't watched for months
• Insurance — you buy excessive insurance to avoid even small loss risks
• Shopping — you don't return items because you'd "lose" what you bought (even though you don't use it)
• Negotiations — you don't ask for a raise because you fear "losing" a good relationship with your boss

Thought experiment

Choose:

• A: You definitely get 500 PLN
• B: 50% chance of 1,000 PLN, 50% chance of 0 PLN

Most people choose A, even though the expected value of both options is identical (500 PLN). This is loss aversion in its pure form.

Now choose:

• C: You definitely lose 500 PLN
• D: 50% chance of losing 1,000 PLN, 50% chance of 0 PLN

Most choose D — they risk to avoid a certain loss. In finance, this means we take greater risks to recover losses.

How to defend yourself?

1. Automation — regular investments (DCA) eliminate emotional buy/sell decisions
2. Stop-loss — set the level at which you'll sell in advance. Don't negotiate with yourself
3. Think in percentages, not amounts — a 5% loss sounds different than "I lost 5,000 PLN"
4. Look at portfolio as a whole — one losing position in a diversified portfolio is normal
5. Check portfolio rarely — the more often you look, the more "losses" you see (myopic loss aversion)
6. Write down your investment plan — and stick to it regardless of emotions
