This framework rejects the convention of building a stock-and-bond portfolio and then bolting on a generic alternatives allocation. The investor first defines goals, liabilities, time horizon, liquidity requirements, and tolerable risks. Each candidate exposure—such as private equity, venture capital, private credit, hedge funds, real estate, infrastructure, co-investments, or secondaries—is then assessed for its distinct role. Public and private holdings are mapped together so duplicated factors and concentrations become visible. Manager alpha, illiquidity, fees, and implementation risks are evaluated deliberately rather than hidden behind a single alternatives label. The output is an integrated portfolio in which each allocation complements the others and contributes to the investor’s desired outcome under a unified risk-control system.

Core principles
- 01Begin with investor goals and constraints rather than asset-class labels
- 02Treat alternatives as distinct tools rather than one homogeneous bucket
- 03Evaluate public and private exposures together
- 04Match illiquidity to the investor’s time horizon and liquidity needs
- 05Pay for alpha only when it adds a differentiated portfolio exposure
- 06Expand access only with appropriate controls and transparency
How to run it
- 1
Define the outcome
Specify the financial objective, liabilities, time horizon, required return, and relevant personal or institutional constraints. Avoid beginning with a fashionable asset class.
Pro tip Translate broad goals into measurable funding, return, income, or resilience targets.
Watch out An undefined outcome makes it impossible to judge whether complexity and illiquidity are worthwhile.
- 2
Establish the liquidity budget
Determine how much capital can remain inaccessible and for how long. Include foreseeable cash flows, benefit payments, emergencies, and capital calls.
Pro tip Stress-test the budget under adverse markets rather than relying on average conditions.
Watch out A long horizon does not eliminate interim cash requirements.
- 3
Assign each exposure a role
State whether each investment is intended to provide growth, income, diversification, inflation protection, or manager alpha. Analyze the underlying asset class rather than the alternatives label.
Pro tip Remove any allocation whose role cannot be explained in one sentence.
Watch out Assets placed in the same category can have radically different return drivers and risks.
- 4
Map total-portfolio exposures
Look through public and private vehicles to identify shared sectors, styles, factors, geographies, and economic sensitivities. Evaluate how the parts work together.
Pro tip Compare a private manager’s exposure with existing public holdings before committing capital.
Watch out Separate risk systems can conceal duplicated growth, leverage, or industry bets.
- 5
Evaluate implementation quality
Assess managers, fees, governance, valuation practices, data quality, and operational controls. Decide where active management has a credible chance to justify its cost.
Pro tip Consider open-architecture manager selection rather than restricting the portfolio to one provider’s products.
Watch out An attractive asset class cannot compensate for poor access, manager selection, or controls.
- 6
Integrate and monitor
Construct the allocation as one portfolio and monitor changing exposures, liquidity, and progress toward the outcome. Update assumptions as public and private holdings evolve.
Pro tip Report risk and outcomes across the entire portfolio rather than by disconnected sleeves.
Watch out Applying only a generic illiquidity premium is too blunt for a complex portfolio.
In the wild
Seitz describes an investor considering a growth-oriented private equity manager. Before paying for that alpha, the investor should determine how the manager’s exposure relates to public-market holdings, factor exposures, and indexed allocations. The private commitment is evaluated as part of the same economic portfolio rather than as a separate alternatives bucket.
→ The investor can detect duplicated growth exposure and decide whether the manager adds genuinely differentiated value.
A hypothetical pension plan with predictable long-term liabilities establishes a liquidity budget, then evaluates private credit, infrastructure, and secondaries by their specific income, diversification, and return roles. The plan maps those exposures against public bonds and equities before allocating.
→ Illiquidity is used purposefully while near-term benefit payments remain protected.
Common mistakes
Bolting on an alternatives bucket
Adding a generic sleeve after constructing a traditional portfolio ignores how its underlying risks interact with existing holdings.
Treating alternatives as one asset class
Private credit, venture capital, hedge funds, real estate, and infrastructure have different mechanisms and must be evaluated separately.
Using a blunt illiquidity premium
A single premium cannot capture manager, factor, leverage, valuation, and liquidity differences across private investments.
Is it for you?
Best for
It is best for long-horizon investors considering private equity, private credit, venture capital, hedge funds, real assets, or secondaries.
Not ideal for
It is not ideal for investors who lack adequate liquidity, risk data, governance capacity, or a sufficiently long time horizon.
From the transcript
“the individual asset classes underneath alternatives quote unquote couldn't be more different.”
“we bolt on alternatives, and that's just not how we construct portfolios today, and it's not how any portfolio for an individual should be constructed.”
“all forms co investment secondaries have to be managed very purposely UM, but with a risk control and an understanding of how those various parts…”
