Defining Base Rates and the 100-Bagger Study

This episode brings together Robert Hagstrom and Chris Mayer to explore how investors should think about base rates, extreme outcomes, and the realities of long-term wealth creation in markets. Drawing on Michael Mauboussin's work, the conversation challenges conventional ideas like mean reversion and highlights why a small number of companies drive most stock market returns—and what that means for portfolio construction.

Matt Zeigler and I had the privilege of hosting Robert Hagstrom (The Warren Buffett Way) and Chris Mayer (100 Baggers) for a special 100-Year Thinkers Edition of the Excess Returns Podcast.
