The break-even effect: why losing makes cautious people reckless
Ritholtz notes traders vowing to sell a junk stock the moment it gets back to break-even, and Schrager says poker players do exactly the same. The break-even effect is a corollary of loss aversion studied by John List: being down produces risk-taking you would never have accepted while up.
- Traders and poker players share the same break-even vow
- It is a corollary of loss aversion, not a separate bias
- Risk appetite inverts only when you are behind
- Related evidence: investors sell winners and hold losers
- Older, more experienced participants fall for it less
“I know this stock is a piece of junk, but dear Lord, if I get back to break even, I swear I'll sell”
“when you're down, you're so determined to win back, so you didn't experience a loss, you double down and take extra risk”
