Dimensional Founder David Booth | Investing, Market Uncertainty and True Wealth

Episode 16 Published 8 hours ago

Description

How should investors navigate market uncertainty without letting fear derail their long-term plans? Dimensional Fund Advisors Founder and Chairman David Booth, a New York Times bestselling author, joins Creative Planning President and CEO Peter Mallouk on Icons and Ideas to discuss the investing principles, academic research, and life lessons behind one of the world’s most influential investment firms.

David shares how studying under Nobel laureate Eugene Fama helped shape his belief in applying the science of investing rather than trying to outguess the market. He takes Peter inside the early days of Dimensional Fund Advisors, from testing the idea of a small-cap fund with institutional investors to working with Vanguard founder Jack Bogle to help launch the firm’s first mutual fund.

David and Peter also explore why uncertainty creates opportunity, the behavioral mistakes that can permanently hurt investors and why remaining invested matters during volatile markets. Beyond investing, David reflects on philanthropy, purchasing James Naismith’s original rules of basketball, the meaning of true wealth and the values that have guided his career and life.
