Geometric Brownian Motion

What It Is

Geometric Brownian motion --- multiplicative random walk (dS/S = μdt + σdW), the basis of Black-Scholes option pricing. Log-normal distribution with positive skew

Interpretation

Standard analysis sees: long-range memory (persistent); nonstationary / drifting. The atlas finds no named structure, but the source is distinctively extreme on Dodecagonal (Stampfli):pisot_triplet_coherence (+3.4z) — beyond what the standard bank predicts for it.
