Why Mega-Cap Concentration Matters

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.

Two legendary investors and authors. One hour packed with timeless wisdom on long-term thinking and wealth creation. This is the conversation we’ve been wanting to have—and we think you’ll find it as valuable as we did.

I’m excited to share this episode with you—it’s reposted here with permission and blessing from both Matt and Jack. Don’t miss it! And follow their work, links below.
