Stay Calm

Learn to Embrace Uncertainty in Investing and Life

Description

"Success—in anything, from fitness to business to investing—comes from discipline and patience, not chasing shortcuts. David Booth, who is a visionary and a great friend, reminds us that staying calm, loving the process, and focusing on what we can control is the real path to lasting results. This book is about building strength the smart way—over time." —Arnold Schwarzenegger, longtime Dimensional shareholder

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.

“Uncertainty isn’t something to fear—it’s where possibility lives.” —David Booth

For more than 50 years, David Booth has been at the center of a monumental transformation in personal finance. As founder of Dimensional Fund Advisors, Booth has worked alongside Nobel laureates Gene Fama, Merton Miller, Myron Scholes, and Robert Merton, helping to transform investing from a game of speculation into a discipline grounded in evidence, diversification, and long-term thinking. In Stay Calm, he shares the lessons, mindset, and stories behind that revolution—and shows readers how to apply them in their own lives.

In this accessible and engaging book, Booth explains why trying to pick stocks or predict the market’s next move is a losing game, and why trusting markets—not gurus—gives ordinary investors a powerful advantage. Drawing on decades of data and experience, he 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.

Reviews

"A relaxed and friendly book anyone can read in a few sittings. It’s partly a memoir about [David Booth's] early years at the forefront of the index-fund revolution and partly a basic guide to lifelong buy-and-hold investing. ...  Booth’s writing is soothing, and his overall message—investing is simply a bet on human innovation and progress—is a truism worth repeating. Young people, in particular, might benefit from reading it."

Jason Zweig, The Wall Street Journal

Arnold Schwarzenegger, longtime Dimensional shareholder

"Booth is a keen observer who draws lessons from his experience as a young shoe salesman, a student, an early proponent of passive investing, and a founder, CEO, and Chairman of a successful money management firm. There are many takeaways. Most will help readers have a good investment experience. All will point readers toward a better life."

Kenneth French, Roth Family Distinguished Professor of Finance, Emeritus, Tuck School of Business at Dartmouth College and Director at Dimensional

"David Booth built one of the most successful investment firms in the world. He had a big idea, the right collaborators, and the discipline to trust evidence over instinct for five decades. 
Stay Calm is the story that legends are created from. And David Booth is the rarest kind of person to learn it from: calm in all circumstances, brilliant, and always willing to try a better way."
