Over the last decade, the investment world has drifted into a simple story: ETFs have won, active managers have lost, and the argument is effectively settled. Low fees, clean index exposure, and fatigue from years of active underperformance pushed trillions of dollars toward passive strategies. Today, ETFs account for roughly 35% of U.S. equity trading volume, a number that would have been unthinkable fifteen years ago.
But the more time I spend looking at how money actually moves—the incentives, the research quality, the dispersion across companies—the more it becomes clear that the passive-versus-active debate is built on an incomplete picture. ETFs solved a real problem. They didn’t eliminate the need for judgment.
The mistake came from assuming the average active manager represented the value of active management itself.
How the Narrative Drifted
When people say active managers don’t outperform, they’re usually referring to long-term studies showing most mutual funds lag their benchmarks after fees. The conclusion sounds airtight: if the majority underperform, why bother trying to pick winners?
But there’s a detail often left out of that story.
A meaningful share of the so-called “active management universe” isn’t actually active. They’re closet indexers—funds that look like the index, behave like the index, and, unsurprisingly, perform like the index. Investors pay active fees for what is effectively a passive product.
Once you strip those funds out, the data changes.
Research by Cremers and Petajisto found that managers with high active share—those willing to hold meaningfully different portfolios—outperformed their benchmarks by about 1.26% per year after fees.
Closet indexers did the opposite: matched the index before fees and underperformed after fees.
Roughly a third of mutual fund assets sat in these benchmark-hugging portfolios. Their inclusion dragged down the “active” category and produced the familiar headline: “active underperforms again.”
The real story wasn’t passive beating active.
It was passive beating closet indexing.
The Market That Made Passive Look Unbeatable
Passive investing benefited from an unusually favorable backdrop:
- Rates were near zero.
- Liquidity was abundant.
- Markets were highly correlated.
- A small group of mega-cap companies dominated returns.
In a world shaped by cheap money and broad asset inflation, simply owning the index captured most of the upside with little decision-making required. That era created the illusion that passive was a complete solution—not just a useful building block.
But markets don’t hold their form forever.
And this one is already changing underneath our feet.
A Different Regime Changes What Matters
Higher interest rates have a way of revealing balance sheet quality. Tight credit reduces the room for error. Dispersion increases. Companies that grew easily in a free-money environment find the next leg harder. The businesses with pricing power, strong margins, and disciplined capital allocation begin to separate from the pack.
These are shifts that quantitative factor models often register late.
They’re also shifts that passive strategies are not designed to respond to.
Passive will continue buying companies because they are in the index, not because they deserve the capital. When leadership changes or valuation gaps widen, passive strategies do not adapt. They follow.
This is the environment where fundamental analysis regains relevance—not because the world returns to the 1980s or 1990s, but because pricing once again reflects business quality, not just liquidity conditions.
Why Stock Picking Isn’t Dead — It’s Just Been Drowned Out
The Graham-and-Dodd discipline remains effective because it doesn’t depend on regimes. It depends on understanding:
- what a business earns,
- how much capital it needs to keep earning it,
- who controls the capital allocation, and
- whether today’s price reflects those realities.
These are not factor tilts.
They’re not machine-generated correlations.
They’re judgment calls grounded in facts.
And when markets are shaped by volatility, not liquidity, these calls matter again. Mispricing becomes more frequent. Narrative and fundamentals diverge more often. Index concentration creates blind spots. And price—the one signal passive investors rely on—loses some of its informational value.
In that context, genuine active management isn’t a bet against the market. It’s a recognition that markets become less efficient when flows, not fundamentals, dominate.
What Likely Comes Next
If we accept that the next decade will look different from the last, then the investment toolkit also needs to shift. Not away from indexing—it’s still an essential foundation—but away from the idea that indexing alone is sufficient.
Three changes stand out:
- Balance sheets matter more when capital has a cost.
- Earnings quality separates winners from followers.
- Concentration increases the risk of owning yesterday’s leaders at full price.
These dynamics create room for fundamental, research-driven active managers—specifically those with high active share—to add value again.
The question is no longer active vs. passive.
It’s skill vs. replication.
The Clear Takeaway
ETFs gave investors a powerful tool. They also reshaped expectations so completely that many concluded active management was obsolete. But the data doesn’t support that conclusion. What it shows, instead, is a need for distinction:
- Passive investing solves for cost and consistency.
- True active management solves for mispricing and dispersion.
- Closet indexing solves nothing.
When the structure of the market shifts—and it is shifting—judgment, fundamentals, and selectivity matter again. The next decade will reward investors who can tell the difference between price and value, index weight and business quality, momentum and durability.
Those distinctions get sharper when liquidity fades.
And that’s exactly where markets are headed.
