FAQ
Reader questions
How did David F. Swensen achieve such strong risk-adjusted returns?
By combining low-cost index funds with a concentrated portfolio of high-conviction active managers, maintaining a long time horizon, and rebalancing disciplined capital across uncorrelated asset classes.
What made Yale’s endowment model unique during Swensen’s tenure?
Its heavy allocation to private markets and real assets, paired with a small number of expert staff, enabled patient capital deployment and reduced reliance on noisy public markets for returns.
How did Swensen’s approach differ from traditional university endowment strategies?
Traditional models relied heavily on public equities and bonds; Swensen shifted toward alternatives, accepted higher direct investing, and emphasized manager quality over passive benchmarks. Scaling limitations, higher talent costs, evolving regulatory expectations, and the need for sophisticated internal governance and due diligence make exact replication difficult for most institutions.
