Applying Base Rates to AI and Macro Trends

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.
