How Smart Investors Think During Booms, Crashes, and Bubbles
Markets repeat because humans repeat. This page is built like a toolkit: the cycle map, signals, traps, and decision rules that keep you rational when the crowd isn’t.
What you’ll learn
This is designed to make you harder to manipulate.
The market cycle (5 phases)
Click each phase. This page updates with signals, traps, and actions.
Phase signals (what to watch)
You never identify a phase perfectly. But you can track behaviors and conditions that repeat. Think “signals,” not certainty.
Signal categories
- Narrative intensity: how extreme and confident are the stories?
- Valuation looseness: are people ignoring price and demanding “inevitable” outcomes?
- Speculation level: leverage, memes, “no downside,” chasing small caps.
- Credit & liquidity: easy money vs tight money conditions.
- Positioning: is everyone already in?
- Forced selling risk: margin, debt walls, refinancing stress.
- Everyone has a “can’t miss” list.
- Valuation stops being discussed.
- People buy because others bought.
- “It’s the future” is used as proof.
- Red days feel endless.
- People sell to stop pain.
- Good businesses get treated as doomed.
- Liquidity disappears (wide spreads, gap-downs).
Why people overpay
Overpaying usually isn’t stupidity. It’s a predictable psychological trap: people confuse recent success with future certainty.
The 8 overpay triggers
- Recency bias: “It went up, so it will keep going up.”
- Social proof: “Everyone is buying, so it must be safe.”
- Narrative addiction: stories feel better than spreadsheets.
- FOMO math: people price in perfection to avoid regret.
- Anchoring: “It used to be $200, so $140 is cheap.”
- Outcome bias: lucky wins get mistaken for skill.
- Confirmation filtering: ignoring the downside case.
- Halo effect: great company ≠ great investment at any price.
Why crashes feel permanent
In a crash, your brain treats drawdowns like danger. That’s why smart people sell at the worst time. The market doesn’t need you to panic — it needs enough people to panic.
Under the hood mechanics
- Loss aversion: losses hurt ~2x more than gains feel good.
- Liquidity stress: margin calls and forced sellers accelerate drops.
- Headline dominance: bad news has higher emotional weight.
- Time distortion: a few red days feels like “forever.”
- Correlation spikes: panic makes everything sell together.
- Volatility feedback loop: higher vol forces de-risking.
Liquidity & rates (why money flow matters)
Markets can rise while the world looks messy if liquidity is expanding. Markets can fall while companies look fine if liquidity is tightening.
Simple mental model
- Easy money: risk assets get rewarded (growth, high beta, speculative).
- Tight money: balance sheets matter (quality, cash flow, defensives).
- Rates: higher rates punish far-future profits more than near-term cash flow.
- Credit: when spreads widen, fragile businesses suffer first.
Capital rotation map
Capital doesn’t disappear — it moves. A lot of “random” market behavior becomes obvious when you track where money prefers to hide or chase.
- Recovery: leaders emerge before headlines improve.
- Expansion: cyclicals + growth often lead.
- Euphoria: most speculative assets outperform.
- Tightening: quality + cash flow wins.
- Panic: everything sells, then defensive holds.
- When others chase: become picky.
- When others panic: become patient.
- When others get “certain”: stress-test.
- When others sell everything: compare business vs price.
Position sizing rules (survival > ego)
Most people lose because they size positions based on excitement, not risk. You don’t need perfect picks — you need survivable sizing.
Practical sizing rules
- Never bet the portfolio: one position shouldn’t decide your future.
- High-risk = smaller size: volatility is a signal, not an invitation.
- Add in layers: buy in increments, not all at once.
- Know your “pain threshold”: if -35% forces you to sell, you sized too big.
- Don’t confuse conviction with leverage: conviction can be wrong.
- Separate “core” from “speculative” buckets.
Interactive tools
These tools are simple on purpose: they force clarity. No fancy indicators. Just decisions.
Position sizing (risk-based)
Convert your risk tolerance into a maximum position size.
Drawdown reality check
See what a drawdown does to your account — and how much recovery is required.
Cycle mood score (behavioral)
Quick scoring: are you acting like a rational owner or an emotional trader?
Valuation sanity check (simple)
A fast “are you paying perfection?” filter (not a full valuation model).
Cycle checklist (use this before buying)
Copy/paste this into notes. Process beats vibes.
1) Can I explain what the company sells in 1 sentence?
2) Where does cash come from — and how stable is it?
3) What would make my thesis invalid?
Cycle check
4) Is this buy driven by fear, logic, or hype?
5) Are valuations pricing in perfection?
6) Are conditions tightening or easing?
Risk check
7) Worst realistic drawdown? (and can I hold it?)
8) Any debt, dilution, refinancing risks?
9) Does position size match risk?
Behavior check
10) If price drops 30% tomorrow, do I panic?
11) Am I buying for dopamine or business value?
12) Would I still buy if nobody could see my portfolio?
