WTT: A New Twist on an Old Bet with Buffett

Episode Summary

Executive Summary: The episode revisits the famous Buffett hedge-fund vs. S&P 500 wager, reflecting on outcome bias, the role of Fed policy, and the charity benefits it created. The host then proposes a new, potentially more apples-to-apples bet: private equity versus the S&P 500, arguing that PE’s leverage, control, and illiquidity may still not be enough to overcome fees and costs.

Main Topics: Reflection on the Buffett hedge-fund bet (Priority: 5/5): The host recounts how the original 10-year wager came about, how it played out, and how it created unexpected relationships, philanthropy, and debate about what the result actually proved. Outcome bias and interpreting performance (Priority: 5/5): He warns against judging decisions solely by outcomes, citing behavioral bias and noting that ex post market conditions can distort conclusions about the original bet’s quality. Charitable and social byproducts of the wager (Priority: 4/5): The bet generated annual dinners, networking with notable investors, and over $2 million for Girls Inc. of Omaha, including the purchase of the Protégé House. Proposal for a new wager: private equity vs. the S&P 500 (Priority: 5/5): The host introduces a new bet idea centered on North American buyouts versus public equities, motivated by private equity’s growing role in wealth management and retirement plans. Why private equity might outperform (Priority: 5/5): He lays out structural advantages for PE—leverage, smaller company size, control, manager dispersion, and illiquidity—that could help offset fees and support returns. Why private equity may still fail to beat public markets net of fees (Priority: 5/5): Despite those advantages, he argues the required performance gap is substantial and estimates the odds of PE outperforming the S&P 500 net of fees are only about 40%.

Key Arguments: The original Buffett bet’s outcome should not be overread because the result was influenced by factors like Federal Reserve intervention and market conditions. Outcome bias is a mistake: a good decision process can produce a bad result, and vice versa. The wager created valuable side benefits beyond investment performance, including enduring relationships and charitable gains. Private equity is a cleaner test than the hedge-fund wager because it more directly reflects Buffett’s original critique of high fees and professional active management. PE has theoretical return advantages from leverage, smaller assets, control, manager selection, and illiquidity, but those advantages may only cover part of the fee hurdle. To beat the S&P 500 over 10 years, PE would likely need roughly a 15% gross return if the index returns 10%, making the challenge difficult. Higher fees, costs, and the end of the long decline in interest rates reduce the historical tailwinds that helped private markets. Even if PE has structural benefits, manager dispersion means success depends heavily on selecting the right firms and execution quality. The host believes the odds are not favorable enough to imply certainty, but still high enough to make the bet intellectually and commercially interesting.

Data Points: Original bet duration: 10 years - The hedge-fund vs. S&P 500 wager ran from January 1, 2008 to December 31, 2017. Warren Buffett's initial odds estimate: 60% - Buffett initially assessed his chance of winning the bet at 60%. Host's initial odds estimate: 85% - The host says he initially thought the odds were 85% in hedge funds’ favor. Charitable proceeds: Over $2 million - Girls Inc. of Omaha received more than $2 million from Warren’s win. Initial bond allocation: $1 million - The wager began with a zero-coupon bond structure based on a $1 million principal. Zero-coupon bond outlay: $640,000 - The bond purchase cost was $640,000, which later grew materially after rates fell. Bond growth: Around 50% - The collateral value increased about 50% after rates dropped to zero. Private equity vs. market leverage: 1.5x debt-to-equity - The host says private equity is roughly 1.5 times debt-to-equity versus about 0.6x for the S&P 500. S&P 500 leverage: 0.6x debt-to-equity - Used to compare public market balance-sheet leverage against buyout leverage. Required PE gross return to beat index: Approximately 15% - Assuming the S&P 500 returns 10% over 10 years, PE would need about 15% gross return to win net of fees. Return gap from leverage: 2-3% - Higher leverage could make up roughly 2-3 percentage points of the performance gap at current rates and spreads. Historical small-cap premium: About 1.5% per year - Over the last century, small-cap U.S. stocks outperformed large caps by roughly 1.5% annually. PE outperformance odds: Around 40% - The host estimates the probability of private equity outperforming the S&P 500 net of fees at 40%. Universe size referenced: 10,000 companies - He notes that 12 deal examples are far from a representative sample of the broader PE universe.

Pivotal Quotes: "resulting, a behavioral bias where people judge the quality of a decision based on the outcome rather than on the decision process itself." — Ted: Explaining why the Buffett wager should not be judged solely by how it ended. "high fees and extra expenses will doom private equity investors." — Ted: Summarizing the likely Buffett view on why PE may fail to beat the S&P 500. "I'd put the odds of private equity outperforming the S&P 500 net of fees at around 40%" — Ted: His bottom-line assessment of the proposed new bet.

Implications: The episode frames private equity’s rise as a test of whether active, fee-heavy ownership can truly outperform public markets. It also suggests a future public wager could sharpen industry debate and reveal unexpected relationships, just as the Buffett bet did.
