    The Math an the History of Investing

    WATCH THE VIDEO Want to build a multi-million-dollar retirement portfolio without gambling on single stocks? This is the first session of the four-part series I recorded for the teachers of Next Gen Personal Finance — and I’m sharing it here with you. In it, I break down the timeless principles, the math and the market history every long-term investor needs to know. WHAT YOU’LL LEARN IN THIS EPISODE• The Math of Compounding [01:43] — how finding an extra 0.5% to 1% in returns — or starting just five years earlier — can add millions to your lifetime wealth.• The Power of Starting Early [09:48] — why your initial investment years build your foundation, and how both bull and bear markets work in favor of young, disciplined savers.• Budgeting Strategy [19:43] — applying the “Pay Yourself First” rule and the 50/30/20 framework to establish sustainable saving habits.• Stocks vs. Bonds [22:44] — understanding why stocks are low-risk for long-term growth, while bonds carry inflation risk over decades.• Market Diversification [30:08] — why 4% of companies generate nearly all stock-market gains, and how owning total-market index funds ensures you don’t miss out on them.• Equity Asset Classes [37:59] — comparing large-cap blend, large-cap value, small-cap blend and small-cap value to reduce volatility and boost returns.• Target-Date Funds [49:38] — why automated, age-tailored allocation helps investors stay the course and avoid emotional mistakes. Tune in to discover how staying the course, keeping expenses low, and letting history guide your strategy can transform your financial future. Join us next week for The #1 Reason to Invest in Index Funds.

    Get Out While You Can or Stay the Course

    Paul opens with news of a new opportunity to reach young investors: a five-part series for Next Generation Personal Finance (NGPF.org), available to some 150,000 teachers who use NGPF's free curriculum. Topics include the math and history of investing, the case for index funds, the inside story on diversification, the $5 million payoff for a financially literate high school graduate, and a teacher Q&A session. Each presentation will be shared with Sound Investing listeners the following week. Then Paul turns to two listener questions that go to the heart of how people actually experience the market. The first asks whether broad diversification really produces the best returns, or whether a more focused portfolio would do better. He walks through the Bessembinder research showing that roughly 4% of companies drove most of the market's long-term return, Fama and French data on small cap value going back almost 100 years, and Vanguard's own real time returns since 1998 comparing $10,000 invested in the S&P 500, mid cap, small cap blend and small cap value asset classes. The second is a letter from an investor who put his first real savings, earned at $7 an hour, into Fidelity Magellan in 1985, lost 30% on Black Monday in October 1987, and pulled everything out. Forty years later he still fears the next crash and asks whether Paul's Ultimate Buy and Hold portfolio could leave him waking up with half his money gone. Paul closes with a story about five 24-year-old engineers he met on Bainbridge Island, and an offer to anyone who can gather a group that would benefit from a conversation about investing.

    Paul Merriman and Rick Ferri: A Conversation Decades in the Making

    Watch the video here. Paul sits down with Rick Ferri — not for a debate, but for the kind of honest conversation two people can only have after spending their careers chasing the same goal from different directions. Rick makes the case against tilting: the small cap premium largely disappeared once the research went public around 1980, and he believes value stopped working around 2006. Paul counters with Table G1b, which shows the results of blending small cap value and the S&P 500 in 10% increments from 1970 through 2025 — returns alongside the worst drawdowns each combination had to survive. Then Rick does something unexpected — he crosses to Paul's side of the table and builds a strong argument for small cap value, framing it as a way to capture the return of private companies that represent half of the economy. Where they land is less about who's right than what it costs to be wrong. If you go down the factor road, Rick says, it's a lifetime commitment — not three years. Also covered: lump sum versus dollar cost averaging, what an hourly advisor can do to help do-it-yourself investors implement their new portfolio, the new Trump accounts for newborns, and why VT may not be your best choice in a taxable account. Both Paul and Rick will be at the Bogleheads Conference, November 13–15 at Green Valley Ranch Resort and Spa in Henderson, NV, near Las Vegas.

    Preparing for an upcoming debate with Rick Ferri: Total Market portfolios

    This Friday I'm sitting down with my friend Rick Ferri for a debate that I think matters a great deal, even though — or maybe because — Rick and I agree on almost everything. We both believe in diversification, low costs, index funds, ignoring predictions, and staying the course. Where we part ways is what happens after that. Rick's case is that you should simply own the whole market. A total stock market index fund gives you thousands of companies at an extraordinarily low cost, and adding complexity rarely pays. My case is that the academic research — Fama, French, and decades of market history — shows that greater exposure to small and value companies may raise long-term expected returns. Rick calls that factor tilting. I call it better diversification. He'll argue I'm not adding diversification at all, just changing the weights, and he's right that this is exactly what we're doing. The question is whether it's worth doing. We also take on a second question that gets far too little attention: if you do want small and value exposure, where should you get it? Vanguard, Fidelity, DFA or Avantis — traditional indexing or systematic portfolio management? Differences that look trivial today can compound into very large ones over 40 or 50 years. Neither of us is trying to win. Rick may be right. I may be right. Ask us again in 50 years. What I hope you take away is the process — examining evidence, understanding the alternatives, admitting what nobody knows, and committing to a strategy you can stick with. Because every strategy disappoints you eventually, and what you do in that moment matters more than which one you chose. The podcast and video of my conversation with Rick will be available Wednesday, August 19, 2026. If you have any questions for Rick, send them to Paul@paulmerriman.com.

    Finding the Perfect Advisor, a Battle Over Words and VT vs. AVGE

    Paul returns from three days at the Garrett Planning Network retreat with a lesson that has almost nothing to do with investments — and everything to do with getting your money's worth from professional advice. Garrett advisors work by the hour, a business model Paul believes eliminates the conflicts of interest built into assets-under-management relationships. For $1,000 to $8,000, he's convinced most families can get extraordinary value from five to ten hours with a thoughtful, trained hourly planner. But there's a catch: the value of those hours depends almost entirely on your willingness to tell the truth. Inspired by a Seth Godin observation — people lie in focus groups, on surveys, and to themselves — Paul explains why the most valuable planning meeting isn't the one where you look financially successful. It's the one where you're completely honest. Paul and his wife are putting this to the test with an hourly planner of their own, and he'll report back in the weeks ahead. Next, Paul shares a private conversation with his longtime friend Rick Ferri, who challenged an idea Paul has taught for decades: that small cap value, large cap value, and international are equity asset classes at all. Rick argues there's only one equity asset class — the total market — and everything else is a segment or style. Paul takes the challenge seriously, does some digging, and explains why the answer matters far more than a debate over definitions. How you think about asset classes shapes the portfolio you'll live with for the next 60 or 70 years. Finally, Paul digs into AVGE, the Avantis globally diversified all-equity ETF, and how it compares to Vanguard's total market approach (VT and VTI). He walks through the meaningful differences: 70/30 U.S./international at Avantis versus 60/40 at Vanguard, and substantially larger positions in mid cap value, small cap value, and small cap blend. He looks at what those tilts have meant historically — including Vanguard's own mid cap value fund turning $10,000 into roughly $160,000 versus $102,000 for the S&P 500 — and why he believes the extra 0.17% in expenses may be money well spent. For investors who don't want to go all-in, Paul offers simple combinations, like a third VT, a third AVGE, and a third AVUV.
