Key Takeaways

  • PitchBook quantitative analyst Andrew Akers argues that private equity indexing is a structural misnomer because buyout returns depend on active operational intervention by dealmakers, not passive exposure.
  • Academic research and PitchBook data indicate that a broad, blind allocation across all private market funds fails to deliver reliable outperformance compared to public market benchmarks.
  • Index products do not replace traditional private fund structures; they introduce a securitization layer that charges new management fees on top of standard 2-and-20 GP economics.
  • Allocators assessing mega-cap buyout vehicles must evaluate underlying financial exposures rather than the private label, since levered public equities often provide identical risk factors at lower cost.

The Indexing Misnomer in Buyout Assets

Wall Street's ongoing push to package private equity into index funds for retail and institutional allocators misinterprets how private capital generates yield. In public markets, indexing works because passive capital captures broad economic growth while driving management fees toward zero. Applying that logic to private buyout funds ignores the mechanics of the asset class.

“When we start talking about the indexing private markets as a product is where kind of the red flag starts to raise for me,” Akers explains. “First of all, I think indexing is a clear misnomer in this sense, right? Indexing I think is synonymous with passive on the public side. There's nothing passive about the buyout universe.”

Private equity investments rely on operational changes, balance sheet restructuring, and direct governance. A manager must actively direct board decisions, recruit executives, and execute acquisitions. Removing active selection eliminates the primary engine of private market alpha.

Fee Stacking Without Beta Outperformance

In public equities, index vehicles deliver beta at single-digit basis points. Private market index wrappers do the opposite. Because the underlying assets remain illiquid partnerships managed by private equity firms, the underlying 2% management fee and 20% carried interest structure remains intact. The index product simply inserts an intermediary.

“And then two on the passive side, passive means to me lower fees,” Akers notes. “Well, we're not going to get rid of the funds, right? The funds are still the operators. So really what we're talking about is a layer on, you know, securitization where there's some financial innovation, but you're still paying the operators on the fund side.”

Paying a double layer of fees might be acceptable if broad private market exposure outperformed public equities. The data shows it does not. “I think most of what our data shows and a lot of the academic research now shows is that if you just blindly allocate to all funds even if it was feasible across private markets it hasn't necessarily been that much of an outperformer relative to public markets if at all,” Akers states.

Exposure Versus Structure: What Does It Actually Do?

As buyout funds swell in size, their performance profiles converge toward levered public equities. Allocators frequently buy mega-fund products under the assumption that the private equity label provides distinct portfolio properties. In practice, the returns often trace standard equity factors amplified by leverage.

Akers highlights a principle from an executive he previously worked with: “My old CEO CIO had a line. He says, 'It's not what it is, it's what it does.' Which sounds kind of obvious, but we go back to these talking about these large private equity. Okay, it's equity. is private equity, but what what does it do to your portfolio and what type of exposures?”

Evaluating mega-cap private funds requires looking through the structure to the underlying risk drivers. If a private vehicle delivers the same exposure as mid-cap or large-cap public equities with debt, paying private market fee structures erodes net returns.

Why It Matters

The rush to manufacture private equity index products signals late-stage fee extraction rather than capital allocation efficiency. As mega-funds face diminishing returns to scale, packaging diversified buyout exposure into retail and wealth-channel products allows sponsors to gather assets without generating upper-quartile alpha. Institutional allocators are increasingly forced to unbundle manager skill from factor exposure, separating genuine middle-market operational value creation from expensive, securitized beta.
