The Rational Reminder Podcast

In this episode, we're joined by David C. Brown, Associate Professor of Finance at the University of Arizona, for a deep dive into the mechanics, performance, and pitfalls of target date funds (TDFs)—the most common investment vehicle in U.S. retirement accounts. David has spent years researching glide paths, benchmarking methods, and industry practices to uncover whether these "set it and forget it" funds actually serve investors well. We unpack why benchmarking TDFs is so difficult, what really drives their underperformance, and how tactical deviations from strategic glide paths often harm investors. David explains how fees, active management, an...

What if choosing your asset allocation was as personal as your life story—and as consequential as your retirement? In this episode, we are joined by PWL Capital's Louai Bibi and Ben Wilson for a deep dive into how advisors guide clients through the most important portfolio decision they'll ever make. Louai walks us through the research, psychology, and planning frameworks behind determining the right stock/bond mix, while Ben shares real-world insights from client cases where risk tolerance, pensions, and life events shifted the balance.

Elie also opens up about the challenges of running a high-stakes nonprofit that directs nearly $400 million annually, why global health in...

In this episode, Ben Felix and Cameron Passmore take a critical look at the Canadian banking system's mutual fund advice model. A newly released study by the Ontario Securities Commission (OSC) and the Canadian Investment Regulatory Organization (CIRO) confirms what many already suspected: Canadian bank branches aren't in the business of giving impartial advice—they're selling financial products. Ben breaks down the implications of this study, which surveyed nearly 3,000 bank-affiliated mutual fund representatives, uncovering troubling statistics about sales pressure, lack of credentials, misaligned incentives, and poor client outcomes. From limited product shelves and high-fee mutual funds to representatives with mi...

What if the most impactful financial advice isn't about picking the right investment—but about understanding human behaviour, simplifying your life, and laughing along the way? In this episode of the Rational Reminder podcast, we're joined by none other than David Chilton, author of the legendary personal finance book The Wealthy Barber. David shares insights from decades of experience helping Canadians improve their financial well-being through simplicity, frugality, and clarity. We dig into the enduring lessons of his 1989 classic, why the new edition took even longer to write, and what's changed (and what hasn't) in the personal finance landscape. Fr...

What if early RRSP withdrawals aren't always the tax-smart move they're made out to be? In this special AMA edition of the Rational Reminder podcast, Ben and Cameron are joined by PWL Financial Planner Louai Bibi for a wide-ranging discussion on RRSP decumulation strategies, insurance planning, and the practical complexities that real clients face when theory meets reality.

"meltdown" strategies) are not always beneficial—especially when viewed through a present-value lens. Louai contributes in-the-trenches experience, highlighting how client go...

What happens when your favourite financial educator's identity is hijacked by scammers? In this episode, Ben and Cameron pull back the curtain on a disturbing but increasingly common reality: sophisticated scammers using Ben's name, voice, and online content to steal from unsuspecting investors. Ben breaks down exactly how these scams work—everything from fake WhatsApp investment groups and cloned emails to AI-generated voice notes and "pig butchering" scams that promise guaranteed returns. You'll hear about pump-and-dump operations, shady PDFs full of financial nonsense, and how scammers prey on optimism, credibility, and fear of missing out. Ke...

In this episode, we welcome back Rob Carrick—one of Canada's most trusted personal finance journalists—for his third appearance on the Rational Reminder podcast.

From the shift from mutual funds to ETFs and the rise of DIY inve...

In this episode, we're joined by Martijn Cremers, Dean of the Mendoza College of Business at the University of Notre Dame and co-author of the groundbreaking 2009 paper that introduced the concept of Active Share. Martijn brings fresh nuance to the long-standing debate over active versus passive management, challenging decades of conventional wisdom built on the foundational 1997 Carhart paper. With his comprehensive research, Martijn argues that dismissing active management may be overly simplistic—especially in less efficient markets like bonds, small-cap equities, or emerging markets. Together, we explore how empirical support for passive superiority has softened in recent decades, the ov...

What if holding just a few "winning" stocks is riskier than it seems? In this episode, Ben and Cameron explore the hidden dangers of concentrated portfolios and unpack the data that makes a strong case for diversification. Drawing from research by Hendrik Bessembinder, J.P. Morgan, and others, Ben lays out the harsh reality behind individual stock returns: the odds are stacked against long-term success. From skewed return distributions and catastrophic losses to behavioral traps like the endowment effect and familiarity bias, this conversation breaks down why most stock pickers lose—and why diversification remains the only "free lunch" in...

We also explore the role...

What if "just buying the market" isn't the end of the story? In this episode, we are joined by Gerard O'Reilly, Co-CEO and Co-CIO of Dimensional Fund Advisors, for a deep dive into what really drives net investment returns. Gerard returns to the Rational Reminder podcast to explain the key principles that differentiate Dimensional's approach from traditional indexing—and why implementation, flexibility, and detail matter so much more than investors might think. We explore the concept of hidden costs in index investing, how index reconstitution and trading frictions erode returns, and the nuanced decisions that shape a market portfolio: de...

For the first time as a host combination, Ben, Dan, and Cameron sit down to discuss the most controversial topics in personal finance. We begin with identity and how it informs decision-making. Then, we revisit the renting versus buying debate, why this remains a highly controversial topic, the ins and outs of income investing, and understating the fervor of dividend investing. We also unpack FIRE as a branch of self-help; how it informs happiness; and how personality influences one's approach to the FIRE principle. To end, we closely examine Bill Bengen's 4% rule, and the Aftershow encourages us to maintain...

Marco Sammon joins Ben and Dan to unpack his latest paper, 'Index Rebalancing and Stock Market Composition', beginning with how Marco's work (co-written by John Shim) compares to the Nobel Prize-winner Bill Sharpe's paper, 'Arithmetic of Active Management.' We investigate the missing links in Sharpe's logic before defining "the market" and ascertaining the main objectives of index funds. Then, we dive deeper into the mechanics of Marco's paper, index and market tracking errors, why delayed rebalancing is more beneficial than instant rebalancing, and the role of technology in the modern tracking error obsession. We also assess the passive-active...
