Jeff Ptak: The Simple Secret to Becoming a Better Investor

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.
