Diversification is not the number of holdings in a portfolio. It is the number of genuinely different economic risks and return drivers the portfolio owns.
Look through funds to exposures
Multiple funds can own the same equities, factors or duration risk. Effective diversification starts with the underlying drivers.
Add different sources of return carefully
Private markets, real assets, alternatives and defensive assets may add different behaviour, but only if they are understood and sized appropriately.
Treat liquidity as an asset
Liquidity provides resilience and optionality. It can allow investors to rebalance or deploy capital when others are forced to sell.
Test diversification in stress
Correlations often change during shocks. Scenario analysis should ask what happens when growth falls, rates rise, funding tightens or risk appetite disappears.
A short decision checklist.
- What job is this capital expected to perform?
- What are the principal sources of return and loss?
- How much liquidity could be needed under stress?
- What assumptions would invalidate the decision?
- What review rule will govern the allocation after the initial decision?
