PE's Secret Sauce: New Index Replicates Buyout Returns in Public Markets

What's New:

According to PitchBook's February 2025 analyst report, Morningstar and PitchBook have launched a groundbreaking index that replicates private equity buyout returns using public stocks, leveraged positions, and AI-driven security selection.

Why It Matters: This development challenges the traditional PE value proposition, suggesting that sophisticated investors can potentially capture PE-like returns without the high fees, illiquidity, and complexity of traditional buyout funds.

Big Picture Drivers:

• Technology: Neural networks can now accurately predict PE buyout targets using financial data

• Strategy: Systematic blend of leverage (1.5x), sector rotation, and value-focused stock selection

• Markets: PE firms increasingly target software companies while avoiding financial services

• Performance: Security selection, not just leverage, drives significant outperformance

By The Numbers:

• 6.1% annual outperformance vs small-cap index (2014-2024)

• 28.9x price/FCF ratio vs 44.1x for small-cap universe

• 33.5% annualized volatility (higher than public benchmarks)

• 13.8% overweight to technology sector vs benchmark

Key Trends to Watch:

• Value Evolution: PE firms define value through free cash flow metrics rather than traditional book value ratios

• Tech Focus: Buyout portfolios have shifted significantly toward software companies

• Risk Reality: PE investments show higher volatility than commonly perceived

• Fee Pressure: Replication strategies may force PE firms to justify their fee structures

The Wrap:

While the index proves much of PE's return profile can be replicated systematically, true differentiation remains in operational improvements and the broader private company universe. This challenges PE firms to demonstrate unique value creation beyond financial engineering.
