Professor Mean

The Mathematician

📐 Swing Trader 📅 146 years old (Born 1880)

"Price is a drunk stumbling home. It may wander, but it always returns to the mean."

Impossibly old—a walking artifact from the Victorian era. Bow tie, antique spectacles, chalk dust on his academic robes. His hands shake slightly, but his mind is sharp.

⚙️ Trading Strategy

Trade 2 standard deviation extremes back to mean

When price moves 2 standard deviations from its 20-day average, the move is statistically extreme. Professor Mean profits from the inevitable return to normalcy.

🎯 Best Suited For

Range-bound stocks and ETFs

"Everything reverts to the mean. Everything."

📜 Why This Strategy Works

Markets overreact. Good news pushes prices above fair value; bad news pushes them below. Extremes are by definition unsustainable.

📊 Entry Signal

📈 Entry Signal

Z-Score ≤ -2.0 (price is 2+ std devs below mean)
→ BUY at current close price

📉 Exit Rules

• MEAN_REVERSION: Z-Score ≥ 0 (price returned to mean)
• STOP_LOSS: Z-Score ≤ -3.0 OR price ≤ entry × 0.92 (-8%)
• MAX_HOLD: Hold time ≥ 10 days

📖 Historical Origin

Origin: Sir Francis Galton's regression to the mean

Sir Francis Galton was a polymath who, in the 1880s, discovered "regression toward mediocrity" while studying hereditary traits. The principle was universal: extreme measurements tend to be followed by less extreme ones.

📖 Understanding Score & Momentum columns
📊 Score — Lifetime Quality Score
Measures how well this strategy+symbol combination has performed across the entire simulation history. Based on return, win rate, drawdown control, profit factor, and trade count. Higher is better.
75+ Elite   60+ Good   40+ Fair   <40 Weak
⚡ Mom — 30-Day Momentum Score
Measures performance over the last 30 days only. Same quality model but calibrated for short-term activity. Captures recent regime shifts that the lifetime score may miss.
75+ Hot   60+ Active   40+ Moderate   <40 Quiet
Spread Indicators — Comparing Mom vs Score reveals regime sensitivity:
🔥 Heating Up — Mom is 20+ points above Score. This symbol is performing significantly better recently than its lifetime average. Could indicate a favorable regime shift.
🧊 Cooling Off — Mom is 20+ points below Score. This symbol is underperforming recently despite a strong lifetime track record. Could indicate an unfavorable regime shift.
No icon = Steady — Scores within ±20 points. Consistent performance.
