From one of the pioneers of index investing and a founder of factor investing comes a clear, calming, and empowering guide to building true wealth—rooted not in predictions, hacks, or market timing, but in the science of how markets actually work.
​

In this accessible and engaging book, Booth explores:

​

• Why market prices reflect information faster than any individual can, and why this is good news for investors
• How to build a resilient, low-stress investment strategy using diversification, discipline, and patience
• How to avoid the emotional traps that cause investors to buy high, sell low, and miss long-term gains
• Why uncertainty is not a danger to be eliminated but a source of opportunity
• What “true wealth” really means—and how money can support a life of purpose, freedom, and meaning

​

Warm, wise, and refreshingly free of jargon, Stay Calm is both a practical guide to long-term investing and a philosophy for living with clarity and confidence. Whether you’re just starting out, rethinking your financial plan, or guiding others, this book will change the way you think about markets, risk, and what really matters.
