Concentration Risk in the S&P 500

Episode Overview

In this wide-ranging conversation, legendary investor Bill Nygren discusses how value investing has evolved since the 1980s—and why the traditional valuation metrics many investors still rely on no longer adequately measure a company’s true worth. Nygren explains how intangibles like brand and customer acquisition costs have transformed the investing landscape, why accounting conservatism can obscure opportunity, and what he learned from Warren Buffett’s purchase of Coca-Cola decades ago.

This episode is a masterclass on adapting a classic investment philosophy for the modern age—combining rigorous analysis with intellectual flexibility.
