David Swensen
About
David Swensen led Yale's endowment from 1985 until his death in 2021 and, along the way, essentially redefined institutional investing.
His "Yale Model" — heavy diversification, meaningful allocations to alternatives, a long time horizon, and hiring best-in-class outside managers — was widely copied by endowments and pension funds around the world.
In Unconventional Success he translated those ideas into something ordinary investors could actually implement: a simple, low-cost, globally diversified portfolio built on index funds — arguing that individuals should not try to imitate Yale's use of private markets.
- Diversification is the closest thing to a free lunch in investing.
- Time horizon is an edge. Most investors squander theirs.
- For individuals: use low-cost index funds; don't try to reproduce endowment complexity.
From the record
Historical positions — for education, not a current portfolio.
- The Yale Model — his famous allocations were asset classes, not individual stocks: early, aggressive moves into private equity, real assets and absolute return.
- Alternatives at scale — meaningful, permanent allocations to illiquid strategies that few endowments had previously embraced.

Swensen redefined how endowments and pensions invest — then, in Unconventional Success, quietly told individuals not to try to copy him and to stick with low-cost index funds instead.
