Loss Aversion

Try this on a friend: "Coin flip. Heads, I pay you ₹150. Tails, you pay me ₹100." Mathematically it's a gift — a 25% expected profit per flip. Most people refuse. Push higher and you'll find they typically need around ₹200 upside to accept ₹100 of risk. That ratio — roughly 2:1 — is loss aversion: losses hurt about twice as much as equivalent gains feel good. It's not a character flaw; it's factory wiring (for our ancestors, losing a day's food mattered more than gaining one).

Now watch what this wiring does the moment money is on a screen:

A position goes into profit → the gain feels fragile, and the fear of losing the gain (a loss!) screams louder than the appeal of more upside → you snatch a quick profit. A position goes into loss → selling would convert paper pain into real, permanent pain → System 1 offers a painkiller: "it'll come back, don't book it" → you hold. Run both instincts for a year and you get the signature retail equity curve: many small wins, a few catastrophic losses — the exact inverse of every successful approach in your Legendary Traders school (Seykota, Jones, Kovner: cut losses fast, let winners run). Loss aversion is why the right way feels wrong and the wrong way feels like relief.

It shows up beyond exits, too: refusing to take excellent bets at reasonable size (the coin-flip refusal, scaled up — skipping A+ setups after two small losses); the paralysis after a big drawdown ("I just can't take another hit"); and the strange comfort of not opening the app when positions are red — if I don't look, the loss isn't real (it is).

Defense — make the loss decision before the loss exists. A stop-loss placed at entry (Kovner's rule: exit decided before entry) is a System 2 decision made while the loss is still hypothetical and painless. Once price is falling and the loss is live, System 1 owns the room — which is why "I'll decide when it gets there" is not a plan, it's a promise to your most biased self. Equally: pre-decide profit targets or trailing rules, so "protect the gain" has a script instead of an impulse.

Offense — loss aversion is why premium exists. Other people's overpayment to avoid losses is a seller's income. Insurance companies are built on it. In markets, the persistent richness of option premium — people paying up for protection against losses they dread — is partly loss aversion, monetized. As a strangle seller, a slice of your edge is this bias, collected from counterparties who pay ₹200 to avoid ₹100-shaped fears. Understanding that is also a warning: the same bias lives in you, and it will whisper "don't book the stop" on the one night that matters.
