Quantitative Risk Management with Python: Value at Risk, Expected Shortfall, and Portfolio Stress Testing

Reactive Publishing Quantitative Risk Management with Python is a practical guide to measuring, modeling, and analyzing financial risk using modern Python workflows. Designed for analysts, traders, students, and quantitative finance practitioners, this book explains how core risk measures are built, interpreted, and applied across real-world portfolios. Readers will learn how to calculate Value at Risk, estimate Expected Shortfall, run portfolio stress tests, analyze return distributions, and evaluate risk under changing market conditions. The book emphasizes clear implementation, practical interpretation, and reusable Python techniques. Instead of treating risk metrics as isolated formulas, it shows how they fit into a broader risk management workflow involving data preparation, volatility estimation, scenario analysis, backtesting, and portfolio-level reporting. Inside, readers will explore: Value at Risk using historical, parametric, and simulation-based methods Expected Shortfall and downside risk measurement Stress testing and scenario analysis for portfolio exposures Volatility, correlation, and distributional assumptions Backtesting risk models and interpreting model limitations Python workflows for repeatable financial risk analysis This book is written for readers who want a structured, applied approach to quantitative risk management without unnecessary theory or promotional trading claims. It provides the tools and context needed to understand risk models, implement them in Python, and use them responsibly in financial analysis.
