Most investors should not try to beat the S&P 500. Over the 20 years ending December 2024, 92% of actively managed large-cap U.S. funds trailed the index, according to SPIVA year-end 2024. A few managers do win, but almost none repeat. For a FIRE portfolio, the honest move is to own the index and stop trying.
Key takeaways
- 65% of active large-cap U.S. funds trailed the S&P 500 in 2024 alone, and roughly 92% trailed it over 20 years (SPIVA year-end 2024).
- The failure rate climbs as the horizon lengthens, which is the opposite of what "give a good manager time" would predict.
- Persistence is near zero: of the funds sitting in the top quartile at the end of 2020, not one stayed there over the next four years.
- Fees, near-instant pricing of information, and the index's self-cleaning cap weighting are why beating it is so hard.
- Warren Buffett's standing advice and his won $1M bet both point the same way: own a low-cost S&P 500 fund.
The data: how often active managers actually beat the S&P 500
The cleanest scorecard on this question is SPIVA, published twice a year by S&P Dow Jones Indices. It corrects for survivorship bias by counting every fund that existed at the start of a period, including the ones that later closed, so the numbers are not flattered by dead funds quietly disappearing.
Here is the share of active large-cap U.S. equity funds that underperformed the S&P 500 through year-end 2024.
| Horizon ending Dec 2024 | Active large-cap funds that trailed the S&P 500 |
|---|---|
| 1 year | 65.24% |
| 3 years | 84.96% |
| 5 years | 76.26% |
| 10 years | 84.34% |
| 15 years | 89.50% |
| 20 years | 91.99% |

Read the last row again. Over two decades, more than nine in ten professional large-cap funds lost to a fund that just buys the index and charges almost nothing. The single-year figure of 65% was actually worse than 2023 and slightly above the 64% average across the 24-year history of the scorecard.
Why beating the index is so hard
Four forces stack against active managers, and none of them are going away.
Fees compound against you. Every dollar of expense ratio, trading cost, and cash drag is a dollar the index does not spend. The math is unforgiving over decades: a 1% annual fee is not a 1% haircut, it is a growing wedge that widens every year you stay invested.
Information is priced almost instantly. The S&P 500 is the most analyzed set of companies on earth. By the time news reaches you, thousands of professionals with faster data have already traded on it. That efficiency is exactly why the average active bet does not pay off after costs.
The index cleans itself for free. The S&P 500 is capitalization weighted, so winners automatically grow into a larger share of the index and laggards shrink out of relevance. Companies that fall behind get removed and replaced. You get that continuous pruning with no capital gains bill and no manager to pay for it.
Survivorship hides the wreckage. Weak funds quietly close, so the surviving lineup looks stronger than the full field ever was. SPIVA counts the closures, which is why its numbers are higher than the marketing you usually see. Over the 20 years to 2024, only about a third of the large-cap funds that existed at the start were still around at the end.
The few who beat it rarely stay ahead
Some funds do beat the S&P 500. The problem is telling skill apart from luck, and the persistence data is brutal on this point. In the SPIVA U.S. Persistence Scorecard for year-end 2024, of the domestic equity funds ranked in the top quartile at the end of 2020, not a single one remained in the top quartile across the following four years. Even the softer test of staying in the top half was cleared by only about 2% of large-cap funds.
Long-run winners exist. Warren Buffett, Peter Lynch in his Magellan years, and a short list of others really did outperform for decades. But you had to identify them in advance, hold through their ugly stretches, and not confuse the next hot fund with the real thing. Yesterday's chart-topper is close to a coin flip on whether it leads or lags next.
That is the trap behind famous active funds. Both the Growth Fund of America and Fidelity Contrafund are large, respected, long-tenured funds, and their records against the index still swing by era. Hedge funds tell the same story: the long-term hedge fund record versus the S&P 500 is why Buffett won his million-dollar bet, in which a plain Vanguard S&P 500 index fund returned about 126% from 2008 to 2017 while the best hedge fund basket managed 88%.
Should you try to beat it?
For almost everyone building toward financial independence, no. The expected value of trying is negative after fees, taxes, and the time you spend on it. You are taking on more risk and more work for worse odds. Buffett has said it plainly: for most people, the best thing to do is own an S&P 500 index fund, and he has directed that most of the cash left to his own family go into exactly that.
There is a narrow case for a satellite of individual picks or an active tilt, but keep it honest. Size it small, treat it as money you can afford to underperform with, and benchmark it against the index every year rather than against your own hopes. If it does not clear the S&P 500 over a full cycle, it was a hobby, not an edge.
The FIRE verdict: own the index
The path to a fat FIRE number does not run through picking the one fund manager who beats the odds. It runs through capturing the market's return at the lowest possible cost, then leaving it alone for decades while it compounds. A low-cost S&P 500 or total-market index fund does that with no research, no manager risk, and no annual guessing game.
Spend the energy you would have spent chasing alpha on the things that actually move a FIRE plan: your savings rate, your asset allocation, tax-efficient account placement, and staying invested through the drops. The index has already won the argument. The smart money mostly stops fighting it. For the full framework, start with the S&P 500 investing hub.
