Boot Camp #2: The Ultimate Buy & Hold Portfolio

In this second session of our 10-part Boot Camp series, we dive into the piece that’s helped shape decades of investing decisions: The Ultimate Buy & Hold Portfolio.

For nearly 30 years, this research—co-created with the late Rich Buck—has explored a simple but powerful question: What happens when you go beyond the S&P 500 and build a lifetime portfolio across 10 equity asset classes?

Starting with data back to 1970, we walk through the math of compounding, diversification, and disciplined rebalancing. You’ll see how adding small amounts of large value, small cap, REITs, international equities, and emerging markets historically increased returns—without meaningfully increasing risk. The result? A dramatic difference over time, powered by patience and structure.

Whether you’re new to these concepts or have followed this work for years, this episode breaks down the numbers, the lessons, and the real-world implications for long-term investors.

This recording is also a tribute to Rich Buck—an extraordinary collaborator whose work on this topic has reached millions of investors.

Download the tables and watch the video, follow along, and join us as we revisit one of the most impactful investing frameworks we’ve ever created—and set the stage for next week’s deep dive into the Sound Investing portfolios.
