Portfolio management has always been a blend of art and science—but today, machines can handle the science far better than humans ever could. In this practical, no-hype guide, Grace Lin Mercer shows you how artificial intelligence reshapes portfolio construction, rebalancing, and risk control. You will learn how machine learning models uncover non-obvious relationships between assets, how reinforcement learning adapts to changing market regimes, and how natural language processing turns news into trading signals. But this is not a get‑rich‑quick manual. Every chapter confronts the harsh realities: most algorithmic strategies lose money, past performance never predicts future results, and leverage can wipe out your account. You will discover how to design robust backtests, avoid overfitting, and evaluate AI systems honestly. Whether you are a self‑directed investor curious about automation or a professional seeking a balanced perspective, this book delivers clarity without exaggeration. Let the machines find your edge—but keep your eyes wide open. Part of The AI Trading Library.
