In this episode, Robert Hagstrom , Chris Mayer , Bogumil Baranowski and Matt Zeigler return for a wide-ranging conversation on how great investors really think. Rather than focusing on formulas, factor labels, or short-term market predictions, the discussion explores investing as a discipline grounded in philosophy, language, psychology, and long-term business fundamentals. Drawing on ideas from Warren Buffett, Charlie Munger, Bill Miller, and thinkers from outside finance, this conversation challenges many of Wall Street’s most common assumptions and offers a deeper framework for making better long-term investment decisions.
