A self-possessed adult woman in a clean, high-end editorial setting for Asset Allocation.

15 / 25 · Asset Allocation

She is not trying to avoid every fall. She is deciding how much of her portfolio faces one shock.

Asset allocation is the mix of exposures you choose before the market tests them. It is exposure management, not a promise of safety.

The lesson

A 50% fall is the same. The portfolio outcome can be €20,000 apart.

Put all €100,000 into the exposed assets in this illustration and a 50% fall leaves €50,000.

Put 60% in those assets and assume the other 40% does not move in that one scenario: the portfolio ends at €70,000. The €20,000 difference comes from the allocation made before the fall.

The other 40% is not automatically safe. Real assets can move together, and allocation cannot repair weak business economics, excessive price, leverage or a missing cash buffer. Use the arithmetic as a stress test, not a promise.

Change the mix and the shock.

A one-shock thought experiment. The allocation outside the shock is held constant only to make the exposure visible; it is not assumed safe.

Understand allocation trade-offs

Help me understand asset allocation as exposure management. Ask about horizon, near-term cash needs, debt, income stability, emergency savings and drawdown tolerance. Explain the trade-offs, including correlation, valuation, leverage and liquidity, without prescribing a portfolio or recommending securities.

Assumptions

Only the exposed portion changes; the rest is held constant for the scenario.
The model excludes correlation, rebalancing, fees, tax, dividends and inflation.
It does not recommend an allocation or predict any asset class.
