Reactive PublishingMarkets do not move randomly. They evolve across hidden geometric structures that traditional linear models fail to capture.Manifold Learning & Geometric Regime Detection for Financial Markets introduces a new framework for understanding market behavior by modeling price, volatility, and correlation dynamics as motion on nonlinear manifolds. Instead of forcing financial data into Euclidean assumptions, this book shows how markets occupy curved, high-dimensional state spaces whose shape encodes regime shifts, structural risk, and instability long before they appear in conventional indicators.Written for mathematically literate quants and advanced practitioners, this book bridges modern geometric machine learning with real-world financial applications. You will learn how spectral methods such as diffusion maps, Laplacian eigenmaps, and graph-based embeddings reveal latent market structure, uncover regime transitions, and expose fragility in volatility and correlation networks. These techniques allow you to detect when markets are compressing, fragmenting, or deforming under stress, signals that classical econometrics routinely misses.Through rigorous explanation and hands-on Python implementations, the book demonstrates how to reconstruct nonlinear state spaces from financial time series, identify persistent geometric features, and build regime-aware risk and trading systems. Emphasis is placed on interpretability, structural insight, and robustness rather than black-box prediction.This book is ideal for quantitative traders, researchers, risk managers, and advanced data scientists seeking deeper structural models of market behavior, beyond factors, beyond correlations, and beyond linear assumptions.If markets have shape, this book teaches you how to see it, and how to act on it.
