The 100 Year Thinkers: Long-Term Compounding in a Short-Term World

In a world where most investors think in quarters, The 100 Year Thinkers offers insights from investors who think in decades. Hosted by Matt Ziegler and Bogumil Baranowski and featuring Robert Hagstrom, and Chris Mayer, this monthly roundtable will tackle many of the issues all of us face as investors, but look at them through the lens of investors who operate over very long time frames. We will cover a wide range of topics ranging from stock selection to portfolio construction to the economy and behavioral finance, but we will do it by focusing on what matters over the long-term.
