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.

📖 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.
