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.

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.

Table G1b — Fine Tuning Table: S&P 500 vs. US Small Cap Value

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. Registration: boglecenter.net/2026conference
