Spoiler: it's brutal.
The 20-year scoreboard
SPIVA (S&P Indices Versus Active) tracks how many professionally managed funds beat their benchmark, counting dead funds too — the ones that quietly closed after bad runs.
| Time horizon | Large-cap funds trailing the S&P 500 |
|---|---|
| 1 year | ~60% |
| 3 years | 77% |
| 5 years | 89% |
| 10 years | ~85–90% |
| 20 years | 93% |
It gets worse across the board: about 91% of mid-cap and small-cap funds trailed their benchmarks over 20 years, and nearly 95% of all U.S. stock funds fell short. International funds? Same story — over 90% trailed.
We are now on track for the 17th consecutive year in which the majority of large-cap managers lagged the index. Not a bad decade. Nearly two bad decades.
What the gap costs in dollars
Over 20 years, the average large-cap fund returned 9.47% per year versus 11.39% for the S&P 500. Two percentage points sounds small. Compounding makes it huge:
- $10,000 in the S&P 500: ~$86,000
- $10,000 in the average fund: ~$61,000
- The stock-picker's toll: ~$25,000 — from a single $10,000 investment
The main culprit is fees. Active funds charge for the privilege of underperforming, and that drag compounds every single year.
"But I'll just pick the winners"
The data kills this too. Funds that outperform in one period rarely repeat. And there's survivorship bias: of the U.S. stock funds that existed 20 years ago, only about 38% still exist today. Fund companies merge or kill the losers, so the "track records" you see are the survivors — the rosy version.
One fair nuance, from Morningstar's 2026 review of SPIVA methodology: when you weight by assets instead of counting funds equally, the picture improves — about 55% of invested dollars underperformed rather than 92% of funds. Big funds do somewhat better than small ones. But even by that generous math, it's roughly a coin flip at best — with higher fees and more risk.
When picking stocks actually makes sense
Honesty requires the exceptions:
- You genuinely enjoy it and treat it as entertainment with money you can afford to lose (the "5% play-money" rule).
- You have a real edge — you work in an industry and understand something the market doesn't. This is rarer than people think and occasionally illegal (insider trading).
- Tax-loss harvesting in a taxable account, which some active strategies do well.
For everyone else: the default should be index funds, and active stock-picking should have to earn its place — not the other way around.
The index-fund playbook
- Total U.S. stock market index fund — the core (expense ratios often 0.03%)
- International index fund — diversification beyond one country
- Bond index fund — scaled up as you age
- Rebalance once a year — that's the entire maintenance schedule
Total annual time commitment: about 30 minutes. Total fees: a few dollars per $10,000 invested. Twenty-year odds of beating the pros: 93%.
FAQ
Q: What does SPIVA stand for?
A: S&P Indices Versus Active — S&P Dow Jones Indices' semiannual scorecard comparing actively managed funds against their benchmarks, with survivorship-bias correction.
Q: Do any active funds consistently win?
A: Some beat the market in individual years, but persistence is the problem: last decade's winners almost never repeat. SPIVA's persistence scorecards show top-quartile funds rarely stay there.
Q: Are index funds risk-free?
A: No. An S&P 500 index fund fell ~19% in 2022 and ~37% in 2008. The advantage is cost and odds, not safety. Diversification and time horizon manage the risk.
Q: What about Warren Buffett?
A: Buffett himself won a famous 10-year bet (2008–2017) that an S&P 500 index fund would beat a basket of hedge funds — and told his heirs to put 90% of his money in an S&P 500 index fund.
Q: What's a good expense ratio?
A: Under 0.20% is good; under 0.10% is excellent. Many broad-market index funds charge 0.03%. Anything above 0.50% needs a very good reason.
