Model Portfolios Work Better for Endowments Than Families
Weatherley-White does not reject models universally. He argues that they work especially well for endowments because cash flows are consistent, time horizons are very long, and personal liquidity surprises are absent; individual families require more flexibility.
- Endowment cash flows can be forecast with greater certainty.
- Institutional models can remain in place for decades.
- Families face births, homes, ventures, and other changing liquidity needs.
- Imitating a successful allocation does not reproduce its institutional advantages.
“model portfolios work really well in that endowment model.”
“imitation is always hard in the capital markets”
