A New Book, A Familiar Message: Stay Calm

We’re excited about the September 1, 2026, launch of Stay Calm: Learn to Embrace Uncertainty in Investing and Life, by David Booth, Chairman and Co-Founder of Dimensional, our oldest strategic partner. Booth and St. Louis native Rex Sinquefield launched Dimensional in the early 1980’s as the first exclusively evidence-based fund company available to the public.
Clients and longtime followers will recognize the words in title because you’ve likely heard them come out of our mouths or read the words in these pages and client letters. Tune out the noise of today’s headlines. Focus on what you can control. And embrace the uncertainty of the market because that very uncertainty is precisely what will reward you as a long-term investor. Hence, it’s why we say: Take the Long View.
In Stay Calm, David shares the lessons, mindset, and stories behind the revolution that transformed investing from a game of speculation into a discipline grounded in evidence and long-term thinking.
Watch this space for details on an exclusive webinar with David Booth. Until then, read what the likes of Arnold Schwarzenegger, Barry Ritholtz, and Errol Morris are saying about Stay Calm below.

“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.”

“No one has done more to bring the SCIENCE of investing to the broader public than David Booth. His commitment to understanding markets—through deep, evidence-based, academic research—is unparalleled.”
—Barry Ritholtz, Chairman and Chief Investment Officer of Ritholtz Wealth Management
“There was a financial revolution in our time, brought about through a combination of computers, data collection, and theory. David Booth and the University of Chicago were at the center of it. Stay Calm is in part a chronicle of this financial revolution. But more relevantly, it’s a story about scientific principles of investing that shows how easy it is today for anyone to invest well.”
—Errol Morris, Academy Award®–winning filmmaker
