Portfolio Construction: How Alternatives Fit Into a Portfolio

Portfolio construction starts with the job an allocation is meant to do. Yield, diversification, inflation sensitivity, and private-market exposure are different jobs.

This article uses controlled examples only. It does not use real client portfolios or real fund holdings.

Key takeaways

• Define the role before selecting a structure.
• Size semi-liquid exposure around liquidity needs, tax form, risk tolerance, and implementation burden.
• Diversification should be tested by underlying exposure, not manager count alone.
• Product surfaces apply these ideas to actual funds; Learn stays with model scenarios.

Define the job

A model allocation can be assigned different jobs:

• Income.
• Private-market growth.
• Real-asset exposure.
• Lower correlation.
• Inflation sensitivity.
• Tax-aware income planning.

Each job creates a different diligence path.

Liquidity ladder

Controlled example: MODEL-PORTFOLIO has three liquidity sleeves:

• Daily liquidity for operating cash.
• Quarterly liquidity for semi-liquid alternatives.
• Locked or long-duration exposure for private commitments.

The portfolio looks diversified only if the client can tolerate the timing of each sleeve.

Correlated liquidity risk

Multiple semi-liquid funds can become constrained at the same time if they share similar investor bases, asset classes, financing conditions, or market stress. Diversification by name is not enough.

Ask:

• Do the holdings rely on the same exit mechanism?
• Do they own assets exposed to the same macro driver?
• Would the client need cash from several semi-liquid holdings at once?
• Are tax forms and subscription cycles operationally manageable?

Replacement risk

Replacing public exposure with semi-liquid exposure changes more than expected return. It can change liquidity, valuation timing, fees, and reporting.

Advisor language

I would size the allocation around the role it serves and the liquidity the client can actually give up, not around the headline yield or private-market label.
