At this scale the interesting questions stop being about which fund to buy. They become questions about concentration, liquidity, currency, governance — and about how much of the gross return survives the year.
What changes at each scaleA portfolio of a few hundred thousand is an allocation exercise. A portfolio of a hundred million is a system with obligations: it has to fund a family's spending, survive a generational transfer, absorb a concentrated position it did not choose, cross borders without creating reporting failures, and do all of that while paying tax every year on whatever it recognises.
Those obligations conflict. Liquidity for spending argues against illiquidity premia. Diversification argues against holding the concentrated stake that created the wealth. Tax efficiency argues for low turnover, while risk management argues for rebalancing. The work is not choosing the best assets. It is deciding which constraint binds, and paying for that decision knowingly rather than by default.
Portfolio Intelligence is the part of this research programme that treats those trade-offs quantitatively — and that insists on measuring them in after-tax, after-fee terms, because that is the only version of the return the family ever sees.
The gap between them is made of fees, taxes and structure. It is the most under-modelled variable in private wealth, and it compounds in exactly the same way returns do.
The same family, the same objectives, different amounts of capital — and materially different answers. These are the thresholds at which the design problem changes character.
Most substantial wealth is created by one thing, held for a long time, and then either sold or not sold. Both choices are expensive, and neither is neutral.
A founder holding a large single position is running an undiversified portfolio with an embedded, unrealised tax liability. Selling converts idiosyncratic risk into a tax event. Holding defers the tax event and keeps the risk. Hedging, borrowing against the position, staged disposal and charitable structures each shift the problem rather than remove it, and each has a cost that can be quantified.
The analysis worth doing is not “should I diversify” — the answer is almost always yes, eventually — but “what does each path cost in expected terminal wealth, and how much of that cost is tax rather than risk”. Where a sale is imminent, that question belongs in liquidity event planning; where it is not, it belongs here.
Two portfolios with the same holdings and the same gross return can compound at different rates. The difference is character of income, turnover, and where the assets are held.
The arithmetic behind each of these is set out in Tax Intelligence, and the container question in Wealth Structure Intelligence.
Private markets are where large portfolios increasingly sit, and where the gap between headline and realised return is widest. Hedge fund strategies that trade actively tend to generate income of an unfavourable character. Private credit distributes interest. Private equity locks capital for years and reports a return that is not a market price.
None of this makes alternatives a bad allocation. It makes them an allocation that has to be underwritten net rather than gross — which is the subject of Alternative Investment Intelligence, and, where the structural response is a policy rather than a portfolio change, of how these strategies behave inside a PPLI policy.
