Key Takeaways
- • In December 2007 Warren Buffett bet that a low-cost S&P 500 index fund would beat a selection of hedge funds over 2008-2017, and the index returned 125.8% (about 8.5% a year) over the period, per the primary source.
- • The five funds of funds selected by Protege Partners' Ted Seides returned between 2.8% and roughly 8.5% over the decade, according to the publisher summary (the upper bound is truncated in the source).
- • The bet's outcome offers a benchmark for allocators weighing active hedge fund fees against passive index exposure.
- • The primary source provides only a publisher summary and page navigation, so detailed fund-level performance and post-2017 index figures are not available from this material.
Summary
Warren Buffett wagered in December 2007 that a low-cost S&P 500 index fund would outperform a basket of hedge funds over the 2008-2017 period. According to the publisher summary, the index returned 125.8% over the decade, roughly 8.5% annually. The hedge fund side was represented by five funds of funds selected by Protege Partners' Ted Seides, whose returns ranged from 2.8% to a figure the source does not fully disclose in the available text.
The result has been widely cited as a clear verdict on the cost and performance of active hedge fund allocation during a decade that included the post-financial-crisis recovery. Funds of funds layer an additional fee structure on top of underlying manager fees, a dynamic that the bet was designed to highlight.
The headline also references what the S&P 500 has done since the wager concluded. The source material available for this summary does not include those post-2017 index figures, so this summary does not attribute any performance data beyond the 2008-2017 window.
Adjacent industry coverage in the same briefing addresses allocation trends, including DACH institutions lifting alternatives to 32.3% of portfolios as hedge funds regain interest, and the consolidation of capital toward large multi-strategy platforms. These items are separate stories and are not part of the Buffett bet outcome.
