ProbabilisticThinking

Trading isn’t just about charts, indicators, or news. It’s about how you think. The best traders rely on mental models—powerful thinking frameworks—to make better decisions, reduce risk, and stay disciplined.
Here are 30 mental models every trader should internalize to gain a lasting edge in the markets:
---

🧠 I. Psychological Models
1. Loss Aversion
Losses feel twice as painful as gains feel good. This leads to holding losers too long and cutting winners too early.
2. Confirmation Bias
You seek out information that supports your existing position and ignore contrary evidence.
3. Overconfidence Effect
A few wins can make you feel invincible, leading to risky or oversized trades.
4. Endowment Effect
You overvalue assets just because you own them, making it hard to exit.
5. Sunk Cost Fallacy
Holding a losing trade just because you've already invested too much.
6. FOMO (Fear of Missing Out)
Jumping into trades late due to hype—often near tops.
7. Status Quo Bias
Sticking to familiar trades, even when better opportunities exist.
8. Recency Bias
Overweighting recent events and ignoring long-term patterns.
9. Availability Heuristic
Making decisions based on vivid stories or recent news, not data.
10. Narrative Fallacy
Believing neat market stories over complex, messy realities.

📊 II. Decision-Making & Probabilistic Thinking
11. Expected Value
Every trade is a bet. Focus on the reward-to-risk ratio and probability.
12. Bayesian Thinking
Update your views as new information comes in.
13. Second-Order Thinking
Think beyond the obvious: “How will others react to this event?”
14. Inversion
Ask: “What would guarantee I fail?” Then avoid those actions.
15. Margin of Safety
Only take trades where downside is limited and upside is worth it.
16. Circle of Competence
Trade only what you deeply understand.
17. Opportunity Cost
Being in a weak trade means missing out on a better one.

📉 III. Market Behavior & Structural Models
18. Mean Reversion
Markets tend to revert to the mean. Extremes don’t last forever.
19. Trend Following
Momentum can continue. Ride the trend until signs of reversal.
20. Reflexivity (Soros)
Market beliefs affect prices, which in turn reinforce those beliefs.
21. Liquidity Cascades
Forced liquidations can exaggerate price moves beyond logic.
22. Fat Tails
Big, unexpected events are more common than most expect.
23. Antifragility
Some strategies gain from disorder. Volatility can be an advantage.
24. Law of Diminishing Returns
More effort, size, or leverage doesn’t always mean more profit.

⏱️ IV. Time & Process Models
25. Compounding
Small, consistent gains build massive wealth over time.
26. Time Arbitrage
Most traders focus on the short term. Long-term patience is an edge.
27. Feedback Loops
Learn from every trade. Improve by reviewing and refining.
28. Regret Minimization Framework
Ask: “Will I regret not doing this in a year?”
29. OODA Loop (Observe–Orient–Decide–Act)
Adapt quickly. Make decisions, act, and refine.
30. Stochastic Thinking
Markets are probabilistic. Focus on process, not outcomes.
