Why Losing $100 Hurts More Than Winning $100
💔 A coin flip: heads you win $150, tails you lose $100. Most people refuse — even though the math favors them — because a loss hurts about twice as much as an equal gain feels good. That glitch quietly wrecks portfolios.
💡 Key idea
Losses hurt ~2x as much as gains feel good — so people sell winners early and cling to losers. Exactly backwards.
🧠 Why it matters
LOSS AVERSION means losses hurt about twice as much as equivalent gains feel good. Sounds harmless, but it drives some of the worst money behavior: people sell their WINNERS too early (to lock in the good feeling) and hold their LOSERS too long (because selling makes the loss feel real). The result is a portfolio of your worst decisions, lovingly preserved.
🌍 In the real world
💡 Classic experiment: offered a coin flip to win $150 or lose $100, most people refuse — even though the odds clearly favor them. The fear of the $100 loss outweighs the bigger potential gain. Scaled up, that instinct wrecks portfolios.
📌 Takeaways
- Losses feel about twice as painful as equal gains
- It makes people sell winners early and hold losers
- Judge by the future, not by the pain of selling
