Episode notes
Private Equity Lags A Fast World
- Private equity remains slow while the broader economy speeds up, creating a mismatch in holding periods and investor impatience.
- That mismatch fuels demand for secondary markets to engineer liquidity rather than wait years for exits.
Secondaries Went From Niche To Core
- Secondaries began as a niche resale channel for LPs but have grown exponentially since the 2010s.
- Increased seller demand and a bigger buyer base transformed secondaries from peripheral to core in private markets.
Always Probe Why Sellers Exit
- Ask why an LP is selling: rebalancing, new CIO strategy, or distress change the quality of assets offered.
- Treat seller motives as a core diligence input before pricing or buying stakes.
