There's a number that the mutual fund industry would rather you never think too hard about. It comes from S&P Dow Jones Indices — the same company that runs the S&P 500 — and it's published every year in a report called SPIVA: S&P Indices Versus Active.
Here's what the most recent 15-year data shows: roughly 88–92% of actively managed US large-cap equity funds underperformed the S&P 500 over a 15-year period, after fees. Depending on the exact report and time window, the figure floats between 85% and 92%. But in no recent 15-year stretch does active management come out looking good.
That's not a fluke. It's not a bad stretch. It's a pattern that holds across time periods, across fund categories, and across most global markets. And yet Americans hold trillions of dollars in actively managed funds — many of them inside 401(k)s they've barely glanced at in years.
So here's what I want to do in this article: show you the actual numbers, explain in plain terms why active management keeps losing, and give you a clear, low-drama path forward. No panic required. Just information, then action.
What the SPIVA Data Actually Says
S&P Dow Jones Indices has been publishing the SPIVA U.S. Scorecard twice a year since 2002. It's not a research paper with an agenda — it's just a comparison: here's what the index returned, here's what active managers in that category returned, how many beat the benchmark?
The results are remarkably consistent. Over one year, active managers fare better — roughly half beat the benchmark in any given year, which is about what you'd expect by chance. But stretch the window out to 5, 10, or 15 years, and the percentage who underperform climbs relentlessly.
From the 2024 SPIVA mid-year report:
- Over 1 year: About 60% of US large-cap active funds underperformed the S&P 500
- Over 5 years: About 78% underperformed
- Over 10 years: About 87% underperformed
- Over 15 years: About 88% underperformed
And that's among funds that survived the full period. SPIVA uses survivorship-bias-corrected data, meaning it accounts for funds that closed or merged — which tends to be the worst-performing ones. If you only measured surviving funds, active management would look even worse.
Mid-cap and small-cap funds look nearly as bad. International equity is somewhat more mixed, but even there, the majority of active managers trail their benchmarks over long periods. The S&P 500 category is simply where the data is clearest and the sample size is largest.
Why Active Management Keeps Losing
This isn't about active fund managers being incompetent. Many of them are genuinely smart, hardworking, and deeply knowledgeable about the companies they analyze. The problem isn't skill — it's math.
Fees are the first culprit. A typical actively managed US equity fund charges somewhere between 0.5% and 1.2% per year in expense ratio. Some charge more. Contrast that with Vanguard's VFIAX (their S&P 500 index fund) at 0.04%, or their VOO ETF at the same rate. Fidelity's ZERO Large Cap Index fund charges literally 0.00%.
That difference looks small, but compound it over decades. A 1% annual fee on a $100,000 portfolio costs you roughly $30,000 over 20 years in lost compounding — and that's assuming the market returns 7% annually. The more your money grows, the more expensive that fee becomes in real dollar terms.
To justify a 1% fee, an active manager doesn't just need to match the index — they need to beat it by enough to cover that fee, plus any trading costs, plus taxes triggered by the fund's buying and selling activity. That's a high bar to clear every single year, for decades.
Taxes are the second problem. Index funds are passively managed — they only buy and sell when the underlying index changes, which doesn't happen often. Actively managed funds trade constantly by design. All that trading generates capital gains distributions that land in your taxable account every year, even if you didn't sell a single share yourself. You're paying taxes on someone else's trades. In a tax-advantaged account like an IRA or 401(k), this doesn't matter — but in a regular brokerage account, it adds up.
The third reason is mean reversion. Even the managers who beat the index in one five-year period rarely repeat it in the next. SPIVA tracks this directly — they look at which funds were in the top quartile of performance over one period, then check whether those same funds stayed in the top quartile. The answer is: mostly no. Performance in one period predicts very little about performance in the next. Past outperformance tends to revert toward the mean, which is the index itself.
Finally, there's the market efficiency problem. When a professional fund manager decides to buy a stock, they're trading against thousands of other professional fund managers who have access to the same filings, the same earnings calls, the same analyst reports. In this environment, finding a genuine edge is extraordinarily difficult. The market is not perfectly efficient — there are genuine mispricings — but most of them get spotted and corrected quickly by the very people trying to exploit them.
The Argument for Active Management (and Why It Usually Doesn't Hold Up)
I want to be fair here, because there are real arguments people make for active management, and some of them are worth taking seriously.
"What about in a down market?" The theory is that active managers can go to cash or reduce risk when markets get rocky, protecting you from drawdowns. The reality is that most don't, and those who do often miss the recovery. Timing the market is famously difficult. The SPIVA data covers periods that include 2008–2009, 2020, and 2022 — genuinely bad stretches — and active managers still lagged on average over the full cycle.
"What about niche markets?" This is a more legitimate argument. In certain less-efficient corners of the market — small-cap international stocks, emerging markets, specific sectors — there may be more room for skilled analysis to add value. The data is less damning in some of these categories. But even there, the majority of active funds still trail their benchmarks over long periods, and identifying the minority who will outperform in advance is nearly impossible.
"What about star managers like Peter Lynch or Warren Buffett?" They exist. Peter Lynch ran the Magellan Fund from 1977 to 1990 and produced extraordinary returns. Warren Buffett's record at Berkshire Hathaway spans decades. But Lynch himself has said that most investors would be better off in index funds. And Buffett's instructions for his own estate after he dies are to put 90% in a low-cost S&P 500 index fund. These outliers knew they were outliers — and they'd be the first to tell you that identifying the next one in advance is a fool's errand.
What Low-Cost Indexing Actually Looks Like
If you've never actually looked at what index fund investing costs and requires, here's what the landscape looks like today.
Vanguard VFIAX — the Vanguard 500 Index Fund Admiral Shares — charges 0.04% per year. It tracks the S&P 500. Minimum investment is $3,000. If you prefer ETFs, VOO is the ETF version with no minimum and the same expense ratio.
Fidelity ZERO Total Market Index Fund (FZROX) has a 0.00% expense ratio. No typo. Fidelity uses it as a loss leader to attract accounts, but it does what it says: tracks the total US stock market at zero cost. Similarly, FZILX tracks international markets at 0.00%.
Schwab's SCHB tracks the Dow Jones US Broad Market Index at 0.03%. iShares' IVV tracks the S&P 500 at 0.03%.
All of these give you diversified exposure to hundreds or thousands of companies, automatic rebalancing as index constituents change, low turnover, minimal tax drag, and a cost structure that doesn't require them to beat anything — because they just hold what the market holds.
You don't need a dozen funds. Many people do perfectly well holding a single total market fund for US stocks, a single international fund, and a bond fund for ballast as they get older. Three funds. Zero guesswork about which manager will outperform.
Three Things to Do After Reading This
I don't want this to be an article you read and forget. If you have money invested anywhere — a 401(k), an IRA, a taxable brokerage account — here are three concrete things worth doing this week.
1. Find out what you own. Log into your accounts and look at the fund names and tickers. If the name includes words like "growth," "value," "opportunity," "select," or a manager's name, it's probably actively managed. If it says "index," "500," or "total market," you're likely already in the right neighborhood.
2. Find out what it costs. Look up the expense ratio for each fund you hold. You can search the ticker on Morningstar.com or the fund company's website. If you're paying more than 0.10% on a broad equity fund, you're paying more than you need to.
3. Consider switching — but do it thoughtfully. In a tax-advantaged account (401k, IRA), switching funds has no tax consequences. In a taxable brokerage account, selling a fund that has appreciated triggers capital gains taxes, so run those numbers before you act. Many 401(k) plans now offer low-cost index options — it's worth checking what's available in yours and moving contributions toward the lowest-cost choices.
None of this requires you to become a financial expert, follow the market daily, or make predictions about what's going to happen next year. That's actually the whole point. The research says you're better off not trying to pick winners — and that the less you tinker, the better your odds.
The fund industry has built an enormous business on the belief that expertise justifies its price. For most people, in most accounts, over most time horizons, the data says otherwise. You don't have to take my word for it. Read the SPIVA report yourself. It's free, it's updated twice a year, and it's the clearest mirror the industry has.
Check what you own. Check what it costs. Then decide.
