Private-market performance remains widely dispersed because investing is an exercise in active ownership rather than standardized security selection. Managers obtain different opportunities, then make consequential choices about leadership, hiring, manufacturing, marketing, culture, and eventual exits. The selection process should therefore trace results back to repeatable capabilities: proprietary sourcing, sound operating judgment, effective management partnerships, and adequate analytical resources. Fundraising totals or industry growth are weak proxies because more capital does not equal better decisions. Investors should compare managers within appropriate strategies and vintages, examine how deals were found and improved, and test whether strong outcomes resulted from identifiable skill. The output is a portfolio of managers chosen for durable decision-making advantages rather than reputation or market momentum alone.
Origin
Extracted from Masters in Business, where Erik Hirsch explained why private-market return dispersion persists and why selecting among thousands of managers requires expertise, data, resources, and technology.
Core principles
- 01Capital flows do not predict manager performance
- 02Operating decisions create divergent outcomes
- 03Proprietary deal access remains consequential
- 04Persistent dispersion makes selection valuable
- 05Data and technology strengthen judgment but do not replace it
How to run it
- 1
Reject capital-flow shortcuts
Do not infer future performance from how much money entered the strategy or how successfully a manager raised its fund. Treat fundraising as context rather than evidence of investment skill.
Pro tip Compare capital raised with actual deployment discipline and realized outcomes.
Watch out Popularity can reflect distribution strength rather than investment quality.
- 2
Map the sourcing engine
Determine how the manager finds investments and whether it receives opportunities unavailable to typical competitors. Examine networks, sector relationships, geographic presence, and direct origination.
Pro tip Request examples showing how specific investments entered the pipeline.
Watch out Claims of proprietary deal flow need transaction-level evidence.
- 3
Inspect consequential decisions
Review what the manager changed after investing, including choices involving management, hiring, culture, marketing, and operations. Link those interventions to company outcomes.
Pro tip Include unsuccessful investments to see how the team responds when its thesis breaks.
Watch out Do not attribute market-wide multiple expansion to operating skill.
- 4
Test repeatability
Compare decisions and outcomes across deals, funds, vintages, and market conditions. Look for a consistent mechanism rather than one exceptional success.
Pro tip Ask whether the same sourcing or operating capability can function at the manager's new fund size.
Watch out Scaling assets faster than capabilities can erase a historical advantage.
- 5
Assess the supporting system
Evaluate whether the manager has enough people, expertise, data, and technology to source, monitor, and improve its portfolio.
Pro tip Match infrastructure requirements to the complexity and geographic breadth of the strategy.
Watch out A strong individual investor may still fail without an institutional process.
- 6
Construct with differentiated managers
Select managers whose evidence supports a durable advantage and combine them without unnecessary overlap. Monitor whether the original sources of advantage persist.
Pro tip Record the specific capability that earned each manager a place in the portfolio.
Watch out Do not let a top-quartile label substitute for an updated investment thesis.
In the wild
Hirsch asks an audience to imagine placing ten different people in charge of the same company for a year. Each leader would make different choices about marketing, manufacturing, hiring, and culture, producing widely different results even though the business and available capital began in the same place.
→ The thought experiment shows why manager judgment sustains wide performance dispersion in private markets.
A hypothetical allocator compares two funds with similar headline returns. One relied on rising valuations, while the other sourced companies through specialized industry relationships and repeatedly improved margins through documented operating changes. The allocator selects the second manager after confirming those capabilities remain intact at the new fund size.
→ The decision rests on a repeatable sourcing and operating mechanism rather than historical returns alone.
Common mistakes
Following fundraising momentum
Capital raised has shown little correlation with private-market performance, so treating inflows as validation can direct investors toward crowded but undifferentiated managers.
Confusing market beta with skill
Strong exits during favorable valuation conditions may obscure whether a manager actually improved its portfolio companies.
Ignoring capacity constraints
A sourcing or operating advantage may stop working when a manager raises substantially more capital than its team and opportunity set can support.
Is it for you?
Best for
It is best for limited partners, advisers, and family offices selecting among many private-market funds.
Not ideal for
It is not ideal for investors who lack access to manager-level evidence or need immediate liquidity.
From the transcript
“capital flows have really not been a good barometer of much of anything.”
“What's going to alter the outcome primarily is what decisions were being made, and were they good decisions or bad decisions.”
“In the private markets, it's really about getting out there, unearthing opportunities, networking, meeting with management teams, meeting with sellers.”
