Hedge funds, as a group, have not beaten the S&P 500 over any recent multi-year stretch. Over the five years through 2025, the HFRI Fund Weighted Composite Index returned about 7.1% annualized versus roughly 14.4% for the S&P 500 with dividends. The honest caveat: hedge funds lost far less in down years, and most are not trying to track stocks in the first place.
Key takeaways
- From 2021 through 2025, the HFRI Fund Weighted Composite gained about 41% cumulatively while the S&P 500 returned about 96% with dividends reinvested. A $1 million allocation grew to roughly $1.41 million in the average hedge fund versus $1.96 million in an index fund.
- Warren Buffett's famous 10-year bet (2008-2017) ended with the S&P 500 index fund up 125.8% and the five hand-picked funds of hedge funds averaging roughly 36%, per Berkshire Hathaway's 2017 shareholder letter.
- Fees explain much of the gap. The classic 2-and-20 has eroded to an industry average of about 1.33% management and 15.8% incentive (HFR, Q4 2025), but that is still 40 to 50 times the cost of an S&P 500 index fund.
- The defensible case for hedge funds is drawdown control, not outperformance. In 2022 the HFRI composite fell 4.25% while the S&P 500 lost 18.1%; in 2008 it fell roughly half as much as the market.
What the scoreboard actually says
The cleanest comparison uses the HFRI Fund Weighted Composite Index, Hedge Fund Research's equal-weighted benchmark of thousands of funds reporting since 1990, against the S&P 500 total return (price plus reinvested dividends).
| Year | HFRI Fund Weighted Composite | S&P 500 total return |
|---|---|---|
| 2021 | +10.3% | +28.7% |
| 2022 | -4.25% | -18.1% |
| 2023 | +7.5% | +26.3% |
| 2024 | +10.0% | +25.0% |
| 2025 | +12.6% | +17.9% |
| 2021-2025 annualized | ~7.1% | ~14.4% |

Note what happened in 2025. Hedge funds posted their best calendar year since 2009 at +12.6%, led by the HFRI Equity Hedge Index at +17.3%, and still finished behind the index. When the industry's 19-year high-water mark loses to a Vanguard fund, the baseline expectation should be clear.
The gap is not new. Most professional money managers fail to beat the S&P 500 over long horizons, and hedge funds carry the heaviest fee load of any of them.
The Buffett bet settled this in public
In 2008, Warren Buffett wagered $1 million (proceeds to charity) that a plain Vanguard S&P 500 index fund would beat any collection of hedge funds over the next decade, net of all fees. Ted Seides of Protégé Partners accepted and selected five funds of hedge funds, which together held stakes in more than 100 underlying hedge funds.
The result was not close. From 2008 through 2017, the index fund gained 125.8% cumulatively, about 8.5% a year. The five funds of funds returned 2.8%, 21.7%, 27.0%, 42.3%, and 87.7%, an average near 36%, or roughly 3% a year. Seides conceded before the final bell rang. The period even began with 2008, the exact environment where hedge funds should have shined, and they did outperform that single year. The following nine years of fee drag erased the head start entirely.
Why the underperformance persists
Fee drag compounds against you. Even at today's eroded averages of 1.33% management and 15.8% incentive fees (per HFR's Q4 2025 industry data, down from the traditional 2-and-20), a fund must generate substantial gross alpha just to match the index net. An S&P 500 index fund charges around 0.03%. Over a decade, that fee differential alone can consume a quarter of your terminal wealth. Funds of funds, the structure Seides picked, stack a second fee layer on top.
The industry is too big to be nimble. Hedge fund assets reached a record $4.98 trillion entering Q4 2025, per HFR. The edge that a $50 million fund exploited in 1995 does not scale to a $50 billion multi-strategy platform competing against a thousand similar firms armed with the same data.
Reported averages flatter the industry. Hedge fund indexes rely on voluntary self-reporting. Funds that blow up or limp along tend to stop reporting, while winners keep publishing. Academic work on survivorship and backfill bias suggests the true average investor experience is worse than the published composites.
Benchmark mismatch cuts both ways. Many funds run 40 to 60 percent net equity exposure or none at all, so trailing a 100 percent equity index in a bull market is partly by design. That defense is legitimate right up until the marketing deck shows equity-like return targets.
The honest case for hedge funds
Dismissing the entire category is as lazy as buying the sales pitch. Three arguments hold up.
Drawdown control is real. In 2022, the HFRI Fund Weighted Composite fell 4.25% while the S&P 500 lost 18.1% and bonds had their worst year in decades. In 2008, hedge funds fell roughly 19% against the market's 37% loss. For a retiree drawing on a portfolio, cutting the depth of drawdowns materially improves sequence-of-returns risk, something a long-term buy-and-hold S&P 500 position cannot do for you.
Dispersion means selection matters more than the average. In 2025, the top decile of HFRI constituents gained 62.7% while the bottom decile lost 12.8%, per HFR. The average hedge fund is a mediocre product, but the category contains genuinely exceptional managers. The catch: the best funds (Renaissance's Medallion being the canonical example) are closed to outside money or gated behind relationships most investors cannot access. If you cannot credibly get into top-decile funds, the average is what you should expect to own.
Uncorrelated return streams have portfolio value. Genuine market-neutral, macro, or relative-value strategies can earn returns that do not depend on equity beta. For a portfolio already saturated with stock exposure, a truly uncorrelated 7 to 8 percent stream can raise risk-adjusted returns even while trailing the index in isolation. The same logic, and the same fee skepticism, applies to private equity's record against the S&P 500.
What this means for a FatFIRE portfolio
If your goal is maximum long-run wealth and you can stomach 30 to 50 percent drawdowns, the data says skip hedge funds and hold low-cost index exposure. The S&P 500's long-run compounding net of a 0.03% fee is an extraordinarily hard benchmark, and you already have access to it.
A hedge fund allocation earns its place only under narrow conditions: you are a qualified purchaser with access to specific managers you have real conviction in (not a fund-of-funds shortcut), you are sizing it as a volatility dampener rather than a return engine, and you have modeled the after-fee, after-tax outcome honestly. Hedge fund gains are also tax-inefficient for U.S. taxable investors, throwing off short-term gains at ordinary rates while an index fund defers nearly everything.
For most wealthy investors, the two-decade verdict stands: the S&P 500 wins on returns, hedge funds win on smoothness, and fees decide the rest. Buy smoothness only if you actually need it, and only at a price that leaves the return worth having.
Frequently asked questions
Have hedge funds beaten the S&P 500 recently?
No, hedge funds as a group have not beaten the S&P 500 over any recent multi-year stretch. From 2021 through 2025 the HFRI Fund Weighted Composite gained about 41% cumulatively while the S&P 500 returned about 96% with dividends. A $1 million allocation grew to roughly $1.41 million in the average hedge fund versus $1.96 million in an index fund.
Who won Warren Buffett's hedge fund bet?
Warren Buffett won. From 2008 through 2017, the Vanguard S&P 500 index fund gained 125.8% cumulatively, about 8.5% a year, while the five funds of hedge funds averaged roughly 36%, or about 3% a year. Ted Seides conceded before the final bell. The bet even started in 2008, the environment where hedge funds should have shined.
Why do hedge funds underperform the S&P 500?
Fee drag is the biggest reason. Even at eroded averages of 1.33% management and 15.8% incentive fees, a fund must generate substantial gross alpha to match an index fund charging around 0.03%. The industry is also too big to stay nimble at $4.98 trillion, reported averages flatter it through survivorship bias, and many funds run partial equity exposure by design.
What is the honest case for holding hedge funds?
Drawdown control is the strongest argument. In 2022 the HFRI composite fell 4.25% while the S&P 500 lost 18.1%, and in 2008 hedge funds fell roughly 19% against the market's 37% loss. For a retiree drawing on a portfolio, cutting drawdown depth improves sequence-of-returns risk. Uncorrelated return streams and manager dispersion also add portfolio value.
