| Chapter | Topic | Ben and David as informed peer | Guest teaching | Guest disagreement | Ben and David pushing back | Why |
|---|---|---|---|---|---|---|
| Framing the Discussion and Introducing Al Rappaport | 4 | 5 | 0 | 0 | David and Ben introduce Mauboussin with deep admiration and frame expectations investing as a key paradigm. Mauboussin recounts his intellectual journey with mentor Al Rappaport and the foundational insight that cash flows, not accounting earnings, determine business value. | |
| The Mechanics of Expectations Investing and Probabilistic Modeling | 6 | 6 | 1 | 1 | Ben demonstrates strong grasp by connecting expectations investing to reverse engineering valuation models into probabilistic distributions. Mauboussin validates and extends this by citing John Burr Williams' 1938 framework for reverse engineering DCF models. | |
| The Structural Shift from Tangible to Intangible Assets | 4 | 7 | 1 | 0 | David asks how modern technology companies complicate expectations. Mauboussin delivers an educational breakdown on the macro shift from CapEx to intangible investments, explaining how traditional accounting distorts income statements. | |
| Venture Capital Paradigms and Reinvestment Economics | 6 | 5 | 0 | 1 | Ben contextualizes venture capital's historical lack of formal financial training and its embrace of intangibles as organic investments. Mauboussin agrees, pointing to Walmart's first 15 years of negative free cash flow as proof that aggressive high-return reinvestment is value-accretive. | |
| Teaching Security Analysis at Columbia and the Genesis of Moat Analysis | 4 | 6 | 0 | 0 | The hosts inquire about Mauboussin taking over Graham's security analysis course at Columbia. Mauboussin shares how a serendipitous interaction with Charlie Wolf launched his teaching career and discusses the difficulty of synthesizing competitive strategy literature. | |
| Measuring the Moat: Competitive Advantage, ROIC, and Industry Dynamics | 5 | 7 | 1 | 1 | Mauboussin systematically lays out his 'Measuring the Moat' framework, defining competitive advantage via ROIC exceeding cost of capital and outperforming rivals. Ben clarifies capital velocity while David contrasts the margin-velocity profiles of Amazon and Facebook. | |
| Complexity Theory, Real Options, and Industry Lifecycles in Startups | 5 | 7 | 0 | 1 | Ben bridges moat analysis into complex adaptive systems and early-stage startup valuation. Mauboussin explains real options theory, showing how high volatility increases option value, and details Steven Klepper's entry-and-exit industry lifecycle curves. | |
| Payoff Distributions Across Venture Capital, Buyouts, and Public Equities | 6 | 6 | 0 | 1 | Ben notes the necessity of extreme outcomes to justify early-stage valuations. Mauboussin outlines empirical return distributions across venture capital (power law), buyouts (moderate skew), and public equities (bell curve). | |
| Reflexivity, Meme Stocks, and Managing Sky-High Market Expectations | 5 | 6 | 2 | 2 | Ben presses Mauboussin on extreme valuations like Tesla and how to handle sky-high expectations. Mauboussin introduces George Soros's concept of reflexivity, explaining how bidding up stock prices enables companies to raise capital and alter fundamental reality, though warning meme runs usually end poorly. | |
| Sponsor Spotlight: Modern Treasury | 0 | 0 | 0 | 0 | Mid-roll advertisement read for Modern Treasury by David and Ben. | |
| Behavioral Decision Tools: Base Rates, Premortems, Red Teaming, and Journaling | 5 | 6 | 0 | 0 | Mauboussin walks through essential behavioral decision-making tools: base rates, premortems, red teaming, and decision journaling. Ben reinforces the base rate concept by reading Kahneman and Tversky's classic Steve the librarian versus farmer thought experiment. | |
| The Paradox of Skill and Untangling Luck from Performance | 5 | 8 | 1 | 1 | Mauboussin unpacks Stephen Jay Gould's 'paradox of skill', explaining how as absolute skill increases and relative skill gaps shrink across domains, luck plays a larger role in determining specific outcomes. Ben and David chime in with sports and market comparisons. | |
| Venture Persistence, Preferential Attachment, and Regression to the Mean | 6 | 7 | 1 | 2 | David and Ben ask Mauboussin to explain venture capital's persistent performance relative to public markets. Mauboussin details his pet theory of preferential attachment and deal flow network effects, proposing a test of partner departures to isolate individual skill from brand signal. | |
| Alpha Compression, Structural Streaks, and Historical Outperformance | 6 | 6 | 1 | 2 | Ben brings up a debate between himself and David over whether anyone will ever match Warren Buffett's 60-year streak given compressed alpha distributions. Mauboussin concurs that narrower standard deviations of excess returns make replication virtually impossible. | |
| Sponsor Spotlight: Fundrise and Real Estate Diversification | 0 | 0 | 0 | 0 | Mid-roll sponsor advertisement read for Fundrise by David and Ben. | |
| Historical Investment Workflows, Career Advice, and Finding 'Easy Games' | 4 | 6 | 0 | 0 | Ben asks what Mauboussin would pursue if he were 18 today. Mauboussin recounts the pre-internet era of faxed research, recommends seeking 'easy games' at the poker table (overlooked geographies, non-indexed equities, or crypto), and reflects on studying computer science. | |
| Trillion-Dollar Market Caps and 20-Year Leaderboard Turnover | 6 | 6 | 0 | 1 | Ben queries if $10 trillion market caps are imminent. Mauboussin quizzes the hosts on market cap turnover since 2001, highlighting that only Microsoft survived the top 10 leaderboard, underscoring the inevitability of long-term corporate turnover. |
