Episode Summary
Executive Summary: Tano Santos and Michael Mauboussin discuss COVID-19 as a temporary but severe economic shock, emphasizing base rates, uncertainty, policy response, and market psychology. They argue that value investors should focus on business durability, leverage, and margin of safety, while recognizing that stress, myopic loss aversion, and collective-action problems can distort decisions and prices.
Main Topics: COVID-19 as a temporary economic shock: The speakers frame the pandemic as a severe but ultimately temporary disruption rather than a permanent destruction of economic capital, citing historical resilience after pandemics and wars. How markets price uncertainty and risk: They discuss the sharp equity selloff, elevated volatility and credit spreads, and how markets may be reacting to both the shock itself and prior valuation excesses. Policy response, externalities, and collective action: They stress that pandemics create huge externalities requiring centralized public-health coordination, and compare responses across the U.S., Europe, and Asia. Value investing and scenario analysis: Mauboussin explains an expectations framework based on sales, costs, and investment, urging investors to test businesses under severe downside scenarios and focus on operating/financial leverage. Psychology, stress, and shortened time horizons: The conversation highlights how stress reduces patience, increases myopic loss aversion, and pushes investors toward backward-looking decisions and professional-risk avoidance. Structural changes in markets and the economy: They note secular declines in interest rates, negative-yielding bonds, rising corporate concentration, and the possibility that post-crisis behavior may alter work, travel, and consumption patterns.
Key Arguments: Pandemics and wars are devastating but typically do not destroy productive capital permanently; economies and markets have historically recovered. Market declines can reflect a mix of permanent-shock fears, valuation correction, and outright overreaction; it is too early to know the exact mix. The key uncertainty is not only the size of the economic shock, but the policy method used to address it; clear protocols can stabilize markets. Pandemics are classic externalities, so decentralized or inconsistent responses are less effective than centralized coordination and enforcement. Investors should analyze businesses through sales, cost, and investment drivers, then stress-test outcomes for operating leverage and financial leverage. A good business is not automatically a good stock: survival through the shock and balance-sheet durability matter. Stress shortens time horizons and encourages backward-looking behavior, which can cause investors to sell or demand too much risk premium after losses. Myopic loss aversion explains why frequent portfolio checking can make investors more risk-averse even when long-run expected returns improve after prices fall.
Data Points: Recording date: March 18, 2020 - The conversation takes place during the early COVID-19 market crisis. Projected U.S. GDP decline: Up to 13% annualized in Q2 2020 - Cited from a Deutsche Bank note to illustrate the severity of the shutdown shock. Comparison to 2008 crisis: More than 1.5x the sharpest contraction in the 2008 global financial crisis - Used to contextualize the projected GDP drop. VIX: Through the roof - Described as a sign of extreme market volatility during the selloff. U.S. 10-year Treasury yield: About 1% - Mentioned as evidence of the secular decline in interest rates. Prior U.S. 10-year Treasury yield range: 1.5% to 1.75% - Referenced as the pre-crisis level before the March 2020 flight to safety. Negative-yielding European investment-grade bonds: About 50% - Used to illustrate unusual global demand for safe assets and low rates. Stress experiment: 25 rounds - In the anecdote about a gambling experiment used to illustrate myopic loss aversion. Performance gap in experiment: People with brain damage played 45% more rounds and twice as many rounds after losses - Used to show how emotional regulation affects risk-taking behavior.
Pivotal Quotes: "We can go back online quite quickly. It's not just evidence coming from pandemics, but even from world wars." — Michael Mauboussin: On why the crisis is severe but temporary, and why economies recover after major shocks. "The key is, I think economics helps you because it puts you in the frame of mind of thinking of this as an externality." — Tano Santos: On why pandemic response requires centralized coordination and policy action. "How bad could this be? And let me, even at this earnings level, and I expect it to recover." — Michael Mauboussin: On using scenario analysis and margin of safety when evaluating distressed stocks.
Implications: Listeners should expect high volatility but should anchor decisions in business fundamentals, downside scenarios, and balance-sheet strength. The episode also suggests policy clarity and centralized public-health action are crucial for restoring confidence.
About Value Investing with Legends
Value investing is more than an investment strategy — it's a fundamental way of thinking about finance. Value investing was developed in the 1920s at Columbia Business School by professors Benjamin Graham and David Dodd, MS '21. The authors of the classic text, Security Analysis, Graham and Dodd were the very pioneers of their field and their security analysis principles provided the first rational basis for investment decisions. Despite the vast and volatile changes in the economy and securities markets during the last several decades, value investing has proven to be the most successful money management strategy ever developed. Value investors' success over the second half of the twentieth century proved not only the validity of the value approach, but its preeminence over even the most widely taught and practiced modern investment theory, which was developed in the 1950s and '60s and remains dominant even today. Our mission today is to promote the study and practice of Graham & Dodd's original investing principles and to improve investing with world-class education, research, and practitioner-academic dialogue. In this podcast you will hear from some of the world's greatest investors, their views on the investment management industry, how they developed their investment process and how they see the field changing over time.
