The largest PE buyout funds have consistently underperformed their smaller peers over the last decade. It's a sign to investors and analysts that investing in mega-funds is fundamentally different from middle-market vehicles.

Our latest analyst note breaks down the emerging differences between these two flavors of PE buyout and explains how they affect deal economics and fund returns. 

Our manager scoring framework shows that the performance of the industry's marquee names is in decline. The capital-weighted average of recent vintages has fallen below the median for all buyout funds.

These managers delivered excellent returns for their LPs through the aughts and early teens, creating a flywheel that led to $5 billion-plus funds and, for some, a public listing of their management companies.

As these managers grew, both their incentives and opportunities changed. Writing checks for hundreds of millions, even billions, of dollars opens a different universe of potential targets. These firms already have sophisticated management and optimized operations—there's less value for a buyout manager to add on the operations side. Instead, these funds are making big macro bets and using their scale to drive revenue for portfolio companies. 

Meanwhile, thousands of middle-market investors are still grinding it out with the same playbook buyout managers have used for decades. Their performance is more volatile, requiring LPs to put in the work to identify managers with real alpha generation. But LPs who get it right see returns the mega-funds simply can't match.
