The SPIVA (S&P Indices Versus Active) U.S. Scorecard has tracked how actively managed mutual funds perform against their benchmark indices since 2002. The methodology accounts for survivorship bias — funds that closed or merged away are still counted as underperformers, rather than quietly dropped from the sample, which is exactly the kind of thing that flatters active management in less rigorous comparisons.

The headline pattern

Across most reporting periods, the majority of actively managed large-cap U.S. equity funds have underperformed the S&P 500 over a one-year horizon — and that underperformance rate has consistently climbed higher over longer horizons, with the large majority of active large-cap managers trailing the index over 10-to-15-year periods. This isn't a one-time bad decade for active managers; it's a pattern that has repeated across very different market environments, bull and bear alike.

Why the odds are structurally stacked this way

The math isn't mysterious. Before fees, active managers as a group roughly mirror the market they're trying to beat — that's close to a tautology, since active managers collectively make up a large share of the market itself. After fees, that "roughly even" starting point becomes a headwind every single year. A typical actively managed large-cap fund charges somewhere in the 0.5%-1%+ range annually, while a broad-market index fund commonly charges 0.03%-0.05%. Over 20-30 years of compounding, that fee gap alone accounts for a meaningful share of the performance difference — before a single stock pick is even evaluated.

A fund doesn't need to be badly managed to underperform its benchmark after fees — it just needs to be average. And by definition, most managers are average or worse relative to their peers, in any given year.

Where active management holds up better

The picture isn't uniform across every market segment. Active management has historically shown a somewhat better track record, though still mixed, in less efficiently priced corners of the market — certain small-cap and international/emerging-market segments, high-yield bonds, and specialized sectors where information is less widely distributed and skilled analysis can matter more. Even there, a majority of active funds still frequently underperform their benchmarks over long periods — the case for active is weaker in less-efficient markets, not strong.

What this doesn't mean

None of this means every actively managed fund is a bad choice, or that no manager has genuine skill — some funds have persistently beaten their benchmarks over long periods. It means identifying which ones will do so in advance, before the track record exists, has proven extremely difficult even for professional fund selectors, and past outperformance has not reliably predicted future outperformance across the industry as a whole.

The practical takeaway

For most investors building a core long-term portfolio, the data makes a strong practical case for low-cost, broad-market index funds as the default — not because active managers are incompetent, but because beating a benchmark consistently after fees is genuinely difficult, and the cost of trying (in fees, and in the risk of picking an underperforming fund) is easy to avoid entirely.
