Fact → Principle → Simulation

• 🟢Daily volatility (ATR): 1.3% of price — Housel's core point: the boring, low-volatility holding is the one you can actually stay invested in long enough to compound.

Fact → Principle → Simulation

• 🟡Composite risk score: 58/100 — Loeb's rule was capital preservation first — missing a gain is far better than absorbing a large loss.
• 🟢Daily volatility (ATR): 1.3% of price — Loeb watched volatility closely — a wild swinger is a much harder position to cut losses on cleanly.

• 🟢Distance above 200-day average: +3.5% — Mackay's delusions always shared one trait: prices detached from any reasonable anchor.
• 🟢RSI(14): 52 — An extreme, sustained RSI is one signature of a crowd already 'all in.'
• 🟡News sentiment score: 80/100 — Near-universal enthusiasm in the coverage is exactly the pattern that preceded every mania Mackay documented.
• 🟢12-period rate of change: +1.5% — A sudden, sharp acceleration is more consistent with mania than with steady, sustainable demand.

Fact → Principle → Simulation

• 🟢Market structure: uptrend — Livermore's first rule: trade with the established trend, not against it.
• 🔴ADX(14): 15 — A strong trend (not a directionless chop) is exactly the setup Livermore waited for.
• 🟢MACD histogram: 0.54 — Positive momentum confirmation supports staying with the trend.
• 🟡12-period rate of change: +1.5% — Livermore read price momentum itself as the most reliable signal available.
• 🟢Volume vs. 20-day average: 1.37x — Livermore looked for volume confirming a move, not a thin, unconvincing rally.

• 🟡Composite risk score: 58/100 — Marks' central argument is that risk-awareness matters more than raw return-seeking.
• 🟢Distance above 200-day average: +3.5% — A stock far above its long-term average is one where the crowd has likely already gotten excited — worth extra caution, not extra conviction.
• 🟡News sentiment score: 80/100 — Marks is explicitly wary when sentiment is near-universally positive — that's exactly when expectations get hardest to beat.

• 🟡RSI(14): 52 — Nelson read cyclical exhaustion and renewal in price oscillation, not just trend direction.
• 🟢Stochastic %K: 39 — A cycle nearing its low end offers more room to move than one already stretched to its high end.
• 🟢Williams %R: -61 — A second, independent read on the same overbought/oversold question.
• 🟡CCI(20): 40 — An extreme reading here is exactly the kind of cyclical extension Nelson's method watched for.
• 🟡Bollinger %B: 0.62 — Position within the recent trading range, a purely statistical cycle marker.

• 🟡Recent insider transactions: 0 buys, 0 sells — Whether management is putting its own money behind the growth story is a real, hard-to-fake signal.

Fact → Principle → Simulation

• 🟡Spread across the other methodologies' scores: ±16 points — Real, independent methodologies converging on a similar view is weak evidence of a genuine, findable edge — wide disagreement suggests there isn't one.
• 🔴Average conviction away from neutral: 8 points — A near-neutral average is exactly the case Malkiel/Bogle expect most stocks to be — no strong signal to act on.
• 🟢Average real-data availability: 75% — A case built on real, available data is at least a fair test — one built on missing data is no case at all.

Fact → Principle → Simulation

• 🟢Distance from 200-day average: +3.5% — Marks' cycle framework treats distance from a long-term anchor as the clearest single cycle-position signal.
• 🟢RSI(14): 52 — An extended oscillator reading is one more sign of a late-cycle position, not early.
• 🟢3-month relative strength vs. S&P 500: +2.1pp — Wild outperformance or underperformance vs. the broad market often marks a crowded, late-cycle trade.
• 🟡News sentiment score: 80/100 — Marks: risk is highest exactly when everyone agrees things look great.

• 🔴ADX(14): 15 — Schwager's wizards consistently avoided directionless chop — a real, tradeable trend is the precondition.
• 🟡Reward/risk to resistance vs. support: 1.18 — Schwager's central lesson: trade setups with real, favorable reward-to-risk, not just a hunch about direction.
• 🟢Volume vs. 20-day average: 1.37x — Real conviction shows up in volume — a setup without it is a much weaker bet.
• 🟢Market structure: uptrend — A defined trend gives a real setup to trade; a range is exactly what disciplined traders wait out.

• 🔴Dividend payments on record: 0 — Smith's central finding was that stocks with reinvested dividends beat bonds over time — a real dividend record is the evidence.
