Jesse is joined by Rubin Miller—former Dimensional Fund Advisors insider, founder and CIO of Peltoma Capital Partners, author of the Fortunes and Frictions blog, and national chess master—for a wide-ranging conversation about how investment philosophy, behavioral discipline, and real-world client psychology intersect. Rubin pulls back the curtain on how factor tilts like small-cap, value, and profitability work. The discussion moves beyond theory into practice, tackling commoditization in passive investing, the tradeoffs between index funds and structured tilts, and the uncomfortable truth that great investment decisions can look wrong for years. Rubin also challenges spreadsheet-only thinking, defending dollar-cost averaging for large windfalls as a behavioral risk-management tool rather than a return-maximization tactic. Throughout, he emphasizes that the most important portfolio design principle isn't squeezing out incremental expected return—it's building a strategy clients can stick with when markets inevitably deliver noise, volatility, and surprise. The result is a candid, technically grounded, and deeply human look at what long-term investing actually demands.

Key Takeaways: • Factor tilts—such as small-cap, value, and profitability—are grounded in decades of academic research but require patience to endure long droughts. • Expected returns dominate over long horizons; unexpected returns dominate in the short run. • Spreadsheet-optimal strategies are not always behaviorally optimal strategies. • The best portfolio is one an investor can stay invested in during extreme volatility. • Financial advisors add value not just through portfolio construction but through expectation management. • Long-term investing success depends less on brilliance and more on discipline, humility, and staying on the bus.
