The Last Step To Successful Investing
Paul starts this letter beginning with a letter from a listener. The letter ends with the reason why our work has had more impact than John Bogle and Benjamin Felix (Both Truth Tellers). The rest of the podcast is focused on a recent article- ⁠The Evolution of Financial Advice, by Ben Carlson. The focus is on the math, history and psychology of investing.Paul concludes that most steps to successful investoring are well documented. But two areas are still open for fine tuning: Portfolio construction and fund selection.

The Biggest Mistake Investors Make
On this podcast, Paul Merriman dives into three big investor questions: Why would anyone add bonds to their portfolio—even in retirement? How has the Ultimate Buy and Hold Portfolio performed in 2025? And how much Small Cap Value should an investor add to VTSAX? Along the way, Paul explains why diversification and balance matter just as much as chasing higher returns.During the podcast Paul references ⁠Table G-1b, Fine Tuning Table: S&P 500 vs. US SCV Equity Porfolio - Out-Performance⁠ and ⁠Table H2a - Sound Investing Portfolios: Comparison Data ⁠, Quilt Chart K1a. He also points to Chris Pedersen’s Best In Class ETF Recommendations and his 2 Funds for Life returns table. These resources provide valuable context for comparing U.S. vs. international returns, equity vs. bond allocations, and how small-cap value can enhance a long-term strategy.
