David Booth, founder of Dimensional Fund Advisors, argues that market data benefits all investors, not just insiders. In a recent podcast interview, Booth discussed how access to complete datasets provides calmness and reassurance during market uncertainty. He traced the evolution of market data, noting that without it, investors were once left in a 'data desert' arguing beliefs rather than facts.

The conversation touched on his collaboration with Eugene Fama and the development of factor investing. Booth also promoted his new book, *Stay Calm: Learn to Embrace Uncertainty in Investing and Life*, reflecting on his Kansas upbringing and views on conventional Wall Street norms. He emphasized that the foundational layer of data was critical to bringing research-backed strategies to the broader investing public.

The discussion highlighted how diversification differs from simple indexing and the science behind factor investing. For those feeling like outsiders in the market, Booth’s perspective offers a data-driven path to confidence.
