Sound Investing

I joined my longtime friend Tom Cock for a special edition of Talking Real Money — a wide-ranging conversation about the evolution of indexing, the proposed changes to the S&P 500, and why investors should understand both the strengths and limitations of traditional index funds. I explain why firms like Dimensional Fund Advisors and Avantis Investors use a more flexible, evidence-based approach than traditional indexing, and how academic research has reshaped portfolio construction over the past several decades.
We also explore lessons from market history, including the importance of understanding major bear markets, determining appropriate risk levels, and building portfolios that align with your personal goals rather than chasing maximum returns. I share insights from the latest Dimensional Matrix Book and explain why I believe studying 100 years of market data helps investors stay disciplined during inevitable downturns.
Finally, I introduce a simple but powerful strategy for helping newborns and young children build substantial retirement wealth through small annual investments that can compound over many decades.

Paul Merriman joins host Roben Farzad on Full Disclosure for a rare conversation alongside Ben Carlson, director of institutional asset management at Ritholtz Wealth and author of the new book Risk and Reward: How to Handle Market Volatility and Build Long-Term Wealth. Roben called it a “truth teller tandem” — the first time these two have sat down together — and the result is an hour of warm, candid, data-grounded talk about how individual investors can actually succeed.
The conversation opens with a great question: does a century of S&P 500 history mean anything when index funds didn’t even exist for most of it? Paul explains why those long-run numbers still matter — not as a promise of the next ten years, but as a guide to the full range of what markets can do. From there, Paul and Ben trace just how far investing has come since Paul entered the business in 1966: the death of the 8.5% sales load, the arrival of IRAs and 401(k)s, fractional shares, and commission-free trading. As Ben puts it, the barriers to entry have been bulldozed, and today’s investor has a better shot at strong net returns than ever before.
But more choices bring more temptation. Paul and Ben dig into diversification as a risk-management tool — why a tilt toward small-cap value and a meaningful allocation to international stocks can pay off over a lifetime, even when the S&P 500 is dominating the headlines. They revisit the lost decade of 2000–2009, the lessons of Japan’s 1989 peak, and the hard discipline of rebalancing into the pain when an asset class is out of favor.
They also get practical about the things keeping investors up at night: inflation as one of the biggest risks most people underestimate, the real trade-offs in today’s bond market and long-duration Treasuries, and an honest look at the FIRE movement — including why meaning, longevity, and a 30- or 40-year retirement complicate the dream of retiring early. Throughout, Paul shares his own story, including why, at 82 and with more than he needs, he still holds half his portfolio in equities because of a caution he’s carried since his twenties.
Ben closes with the thought that may stay with you longest: the most important thing an investor can understand is not the market — it’s themselves. Knowing which mistake you’d regret more, and what you can truly live with, is the foundation everything else is built on.

I recently sat down with Steve Chen on his Boldin Your Money podcast for a wide-ranging conversation about evidence-based investing — and why it matters more than ever in a world of speculation, hype, and constant financial noise. We covered my early days as a stockbroker in the 1960s, the psychology that trips investors up in downturns, how low-cost index funds transformed personal finance, factor investing and small-cap value, and why younger investors are being pulled toward gambling-like behavior through apps, crypto, and prediction markets. Whether you're just starting out or planning for retirement, I think you'll find it time well spent.

In Session 3 of the 2026 Bainbridge Community Foundation Spring Financial Education Series, Paul sits down with Mike Piper — CPA, Personal Financial Specialist, and the voice behind the Oblivious Investor blog and the free Open Social Security calculator — for one of the warmest, most practical conversations of the series. Mike has a rare gift: taking the topics that intimidate most investors and making them feel obvious. Over the course of the hour, he and Paul work through the handful of decisions that genuinely shape a retirement.
Mike opens with a quietly radical idea: if you've prepared well, "more than enough" isn't the exception — it's the most likely outcome. Because we have to plan for long lifespans, poor markets, and high medical costs that usually don't all come to pass, most disciplined savers end up with leftovers. From there, he explains which dollars to spend first each year, how age and capital gains should steer whether you draw from taxable or retirement accounts, and why the step-up in basis matters more than most people realize.
The conversation turns to the human side of money, too — how to talk a couple through it when one spouse is aggressive and the other can't stand the thought of the stock market, why both positions are almost always driven by fear, and how framing the trade-offs around the people you love often brings them closer together. Mike and Paul also tackle the spendthrift-child dilemma, the case for matching a young person's Roth IRA, and why small gifts early can dwarf an inheritance received at 70.
On Social Security, Mike makes the point that most people get the risk exactly backwards: delaying benefits isn't a gamble — it's insurance against the scary scenario of living a very long time. He walks through what really happens if Congress does nothing before the trust fund shortfall around 2033 (hint: the program doesn't disappear), and the range of fixes on the table. Throughout, both men return to the same theme — simple, low-cost, broadly diversified portfolios keep beating the clever alternatives, and the Bessembinder research helps explain why.
Stick around for the closing exchange on using AI to learn from the "Truth Tellers" — and Mike's cautionary tale about a chatbot that invented an entire tax-code provision, word for word and completely convincingly, that simply does not exist.
