The Long View

Today’s guest on The Long View is David Booth. David is a repeat guest, the founder of Dimensional Fund Advisors, and has just released a new book titled Stay Calm: Learn to Embrace Uncertainty in Investing and Life. One of the interesting through lines on the episode really centered on data. David explained that without data, people are just arguing beliefs. There was so much time within the industry where investors really were in a data desert. That foundational layer was critical to everything that David, his colleagues at Dimensional, and so many others around the broader investing industry have ultimately brought to bear for the benefit of so many investors over the years. Plus, David explained that having access to a more complete dataset can really help provide a sense of calmness and reassurance for investors, even in an uncertain environment.

Our guest on the podcast today is Jeff Ptak. He’s a longtime Morningstar employee and currently serves as managing director for Morningstar Research Services. He originally joined Morningstar back in 2002 as a senior mutual fund analyst. Jeff was one of the original two co-hosts of this podcast and regularly posts his thoughts on Morningstar.com, Substack, X, and LinkedIn. Ptak’s work really focuses on investor outcomes. One of the highlights from the podcast today was when Ptak talked about how such a small number of stocks tend to generate a disproportionate amount of the market returns and what that means for diversified actively managed funds. He also discusses what target-date funds get right for investors, as well as what some of them may be missing.
