We explore the mathematics of compounding, the surprising relationship between leverage and long-term returns, and the competing effects of what Chris and...

In this episode, we welcome back Alex Edmans, Professor of Finance at London Business School and author of Grow the Pie, May Contain Lies, and The Madness of Markets. Drawing on academic research and real-world market examples, Alex explores how emotions, social influence, and psychological biases shape investor behavior—and why even apparently irrational markets can be difficult to beat.

We examine how a country's stock market can react to a football loss, why investors overreact to exciting stories and underreact to less visible information, and how identical assets can trade at different prices. Alex al...

In this episode, Ben Felix, Dan Bortolotti, and Kelly Thomas revisit some of the blind spots from their recent discussion about the finances of marriage before diving into a deeply nerdy discussion about leveraged ETFs. Kelly brings a different perspective to questions around spending roles, career sacrifices, financial autonomy, and the mental load of managing household finances.

The main discussion explores leverage, human capital, volatility drag, and the long-held belief that daily resets make leveraged ETFs poor long-term investments. Ben explains how his own thinking changed after feedback from the Rational Reminder community and a...

In this episode, we're joined by Victor Haghani, founder of Elm Wealth and co-author of The Missing Billionaires, for a wide-ranging conversation about how different types of investors shape financial markets. Victor explains the framework behind his forthcoming paper, Who Killed the Random Walk?, and how fundamental investors, static investors, and extrapolators interact to produce momentum, excess volatility, and other market anomalies.

We explore why return chasing is different from momentum investing, how investor flows and inelastic demand can move markets, and how the Merton share connects expected returns and risk to portfolio allocation. Victor also discusses...

We also discuss the role...

In this episode, we're joined by Matthew Taylor, a litigation lawyer with Sotos Class Actions in Toronto who represents retail investors and pension funds in securities class actions. We take a deep dive into what makes a successful negligence claim against a financial advisor, how courts assess fiduciary relationships in Canada, and what investors should look for when evaluating the people managing their money.

We explore the evidence that can strengthen or weaken a negligence claim, from one-size-fits-all portfolios and unexplained trades to poor communication and failures to account for changing life circumstances. Matthew also...

In this episode, Ben Felix, Dan Bortolotti, and Ben Wilson take a research-driven look at the finances of marriage, from spending personalities and prenuptial agreements to wedding costs, joint accounts, financial infidelity, and household decision-making. The conversation explores how the way couples think about and manage money can affect both financial outcomes and relationship satisfaction.

We unpack the difference between being frugal and being a "tightwad," why tightwads and spendthrifts may be drawn to each other despite having more conflict later, and how simply understanding your partner's spending tendencies can improve financial conversations. We also...

In this episode, Ben Felix and Dan Bortolotti take on 10 of the biggest myths in personal finance and investing.

We explore why material purchases often lose their appeal quickly, why autonomy can be one of the best things money can buy, and how worrying about money can be a greater problem than spending it. Bill also discusses the four horsemen of financial disaster—inflation, deflation, co...

Barry Ritholtz returns to the Rational Reminder podcast to discuss the biggest mistakes investors make—and why avoiding them may matter more than finding the next great investment.

What if the way we think about investing—and expected returns—was fundamentally incomplete?

In this episode, Ben Felix and Dan Bortolotti take a deep dive into one of the most influential papers in financial economics: Fama and French (1993). With nearly 15,000 citations, this research reshaped how we understand asset pricing by showing that market beta alone isn't enough to explain returns. Instead, multiple factors—specifically size and value—play a critical role.

Ben and Dan unpack how this paper challenged the dominance of CAPM, introduced the now-famous Three-Factor Model, and laid the foundation for decades of empir...

In this episode, we unpack the growing tension in private markets—private equity, private credit, and private real estate—and examine whether their long-standing appeal holds up under scrutiny. With increasing pressure to bring these investments to retail investors, the discussion explores how illiquidity, valuation opacity, and complex fee structures may be masking risks rather than reducing them.

Merton, later extended by Francisco Gomes and co-authors, and now made dramatically more usable through a spreadsheet-based approximation.

What makes this conversation so compelling is not just the crime, but how ordinary it felt at the time. Tom explains how small rationalizations, cultural pressures, ambition, and the normalization of questionable be...

In this episode, we welcome back return guest Hank Bessembinder for a deeply analytical conversation spanning leveraged ETFs, volatility, and the future of performance measurement. Hank walks us through his latest research on leveraged single-stock ETFs, clarifying the misunderstood concept of "volatility decay" and decomposing returns into rebalancing effects and frictions. The results are striking: meaningful underperformance relative to simple levered benchmarks, driven by both embedded costs and the mechanics of daily resets. In the second half, we shift gears to a more foundational question: What is a return, really? Hank challenges the dominance of arithmetic averages and even...

Equal-weighted index funds sound like an elegant solution to some of today's biggest investor anxieties: high market concentration, elevated valuations, and outsized influence from a handful of mega-cap stocks. In this episode of the Rational Reminder Podcast, Ben Felix, Dan Bortolotti, and Ben Wilson take a deep, evidence-based look at whether equal weighting actually improves portfolios—or simply introduces new risks under a different name. The discussion breaks down how equal-weighted indices differ fundamentally from traditional market-cap-weighted indexes, why equal weighting has historically outperformed in certain periods, and what's really driving those results beneath the surface. The team explains ho...
