This method begins with the investors required outcome rather than with a fund or asset-class recommendation. The team defines liabilities, target returns, liquidity needs, risk tolerance, time horizon, and gaps in the existing portfolio. It then constructs a holistic solution from public and private assets, using scalable beta as a foundation and adding alpha, diversifying strategies, or completion exposures where they improve the mandate. Portfolio construction and risk management determine how the pieces interact, while stress testing checks whether the total portfolio can withstand relevant shocks. The output is a customized risk-adjusted return profile, not merely the highest standalone alpha available from an individual strategy.
Origin
Vassalou presented this approach as the emerging middle ground between passive investing and traditional hedge funds for institutions with large, complex mandates. Extracted from Masters in Business.
Core principles
- 01Start with the investors need rather than a product
- 02Treat liabilities, liquidity, return targets, and existing holdings as design constraints
- 03Use public and private assets as components of one portfolio
- 04Combine beta, alpha, diversification, and risk control
- 05Judge success by the required risk-adjusted outcome
How to run it
- 1
Define the required outcome
Specify liabilities, target return, risk tolerance, horizon, and any required funding or spending profile.
Pro tip Translate broad aspirations into measurable portfolio objectives.
Watch out A vague objective encourages product selection without a reliable success criterion.
- 2
Set liquidity constraints
Determine how much capital must remain accessible and when cash may be required.
Pro tip Model both ordinary cash needs and stressed liquidity demands.
Watch out Private assets can create hidden fragility when liquidity needs are understated.
- 3
Map the existing portfolio
Measure current exposures, concentrations, gaps, and unintended factor risks.
Pro tip Evaluate economic exposures across asset-class labels.
Watch out Adding a new strategy without mapping existing holdings can duplicate risk.
- 4
Design the architecture
Choose a mix of public and private assets that can meet the mandate at the required scale.
Pro tip Use beta for scalable core exposure and reserve scarce capacity for differentiated alpha.
Watch out Do not treat every attractive asset as suitable for the total portfolio.
- 5
Optimize interactions
Evaluate correlations, diversification, leverage, downside risk, and how each component contributes to the whole.
Pro tip Judge components by marginal portfolio contribution rather than standalone returns.
Watch out Historical correlations may fail during the stress scenarios that matter most.
- 6
Stress-test the solution
Test the portfolio against economic, market, liquidity, and liability scenarios relevant to the investor.
Pro tip Include scenarios that affect both assets and liabilities simultaneously.
Watch out A return target is meaningless if the investor cannot survive the path taken to reach it.
- 7
Monitor mandate fit
Review whether changing markets, liabilities, or client needs require the portfolio to evolve.
Pro tip Use mandate-level metrics rather than evaluating each manager in isolation.
Watch out A once-suitable solution can become misaligned as constraints change.
In the wild
A pension fund has a diversified public portfolio but needs a specific return, predictable liquidity, and better protection against liability shocks. The team maps its existing exposures, retains scalable beta, adds targeted alpha and diversifiers, and selects private assets only where the liquidity budget permits.
→ The resulting portfolio is aligned with the funds liabilities and risk budget rather than assembled from disconnected products.
Common mistakes
Starting with the product
Choosing a favored fund first can force the investors needs to fit the product instead of designing around the mandate.
Maximizing alpha in isolation
Standalone alpha does not guarantee the liquidity, scale, or total risk profile required by a large institution.
Separating public and private books
Analyzing them independently can hide combined concentrations, liquidity demands, and correlated economic exposures.
Is it for you?
Best for
It is best for large institutional investors whose needs cannot be met by passive exposure or standalone hedge-fund products.
Not ideal for
It is not ideal for investors who lack clearly defined objectives, constraints, or reliable information about existing exposures.
From the transcript
“the future of the industry is really in the solutions space.”
“what the demand is for creating holistic portfolios that incorporate as classes from the whole spectrum of assets out there, whether it's in public markets…”
“try to provide the right the profile of risk adjusted returns for the particular needs of the investor, incorporating alpha in there, but not just…”
