100 Year Thinkers, Ep. 6 | Chris Mayer & Robert Hagstrom: Most Stocks Don’t Matter & The Outliers That Break Base Rates

About this episode

The episode discusses how a small number of companies drive most stock market returns and the implications for investors.

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.
