One in eight active large-cap funds beats the index over a decade

Only 27% of actively managed U.S. large-cap funds beat a comparable passive investment in the 12 months through June 30, according to Morningstar data cited by The Wall Street Journal and carried in AdvisorHub's August 17 market brief. Over a decade the share falls to 13%. Seven of every eight lost.

The numbers land at an uncomfortable moment for the stock-picker narrative. The argument of the moment holds that AI-driven disruption has widened the gap between market leaders and laggards, which should reward careful stock selection. The year through June put that theory to the test: three of four active large-cap funds trailed.

The advisor conversation starts where these odds meet the fee schedule. A 13% win rate over a decade is not the kind of odds that justify much of a fee gap. It is the kind of odds that justify a cheap core, an explicit case for every deviation, and a fee discussion before the buy ticket.

The theory is being tested in real time. Large asset managers, per the brief, are shifting their AI focus from whether enormous capital spending will pay off to which companies will capture the resulting profits. Cloud results from Microsoft and Amazon have reassured demand, and Reuters estimates hyperscalers could generate about $340 billion more annual operating cash flow in 2027 than in 2025. That is the fertile ground stock pickers say they want. The base rate says most still won't beat the index there: 27% is the result even when conditions are favorable.

None of this argues for an all-index book. It argues for an index default with active sleeves that earn their slots. A concentrated manager with a defined process, a narrow mandate, and a fee that doesn't eat the edge can still win. The requirement, given the base rate, is a thesis written before the trade: what the index is missing, why this manager is the one to catch it, and what the fee is allowed to cost.

The base rate is a starting point, not a verdict on any single fund. A decade of outperformance, a narrow mandate, and a fee below the category average are the exceptions inside that 13% — roughly one fund in eight occupies that space. The due-diligence job is to find that fund, or accept the odds and keep the index. Both are defensible; neither should surprise the client.

The brief's own caution is the part to repeat in client meetings: the active case weakens especially when higher management fees are included. Whatever the fee treatment in the headline number, the gap between an active fund's expense ratio and the index fund's is a drag the pick has to overcome before it adds anything. For most large-cap active funds, the arithmetic never gets there.

The same brief carries a reminder of where the real winners have been. Harvard Management Company disclosed a $2.2 billion position in SpaceX, its largest individual U.S. stock holding, in its latest filing. The University of California has reported a substantial position as well. Both disclosed after SpaceX's record-setting June IPO. Endowments can hold concentrated, long-duration venture bets because their spending horizons tolerate the risk. That payoff is real, and so is the concentration risk; the lesson does not translate into a client's IRA.

None of this tells an advisor which fund to buy. It tells them what to ask before buying one. These base rates are the honest starting points; the rest is pitch.
