Hot-Hand Fallacy

The mistaken belief that a winning streak signals durable skill rather than noise. Causes traders to size up dangerously after consecutive wins, producing drawdowns larger than the streaks that preceded them.

Psychology Recency Bias Overweighting recent events when forming judgments. In memecoins: treating the last three trades as definitive evidence of skill or its loss. Produces the hot-hand fallacy (size up after wins) and the cold-hand fallacy (stop trading after losses), both of which are expensive errors. → Psychology Cold-Hand Fallacy The mirror error to the hot-hand fallacy: believing a losing streak signals lost skill rather than variance. Causes traders to stop trading entirely after consecutive losses, often missing the rotation into a new meta. → Psychology Stake-vs-Survive The sizing principle that a -100% outcome on any position must not compromise the trader's ability to continue trading. Stake is what you risk; survive is what you must preserve. Critical for memecoins because -100% is the modal outcome (98.6% of Pump.fun tokens end below $1,000 in liquidity), not a tail event. →
