David Swensen

David Swensen (1954-2021) was the Chief Investment Officer of Yale University's endowment from 1985 until his death in May 2021. He held a PhD in Economics from Yale, where he studied under James Tobin (Nobel laureate). Before returning to Yale, he worked at Salomon Brothers and Lehman Brothers on Wall Street, where he helped structure the first-ever currency swap transaction. Swensen gave up a far more lucrative Wall Street career to manage Yale's endowment at a fraction of the compensation, driven by a mission to serve the university. He authored two influential books: 'Pioneering Portfolio Management' (2000, for institutional investors) and 'Unconventional Success' (2005, for individual investors). He mentored an entire generation of endowment CIOs -- many of the best-known institutional investors (including several on this list) trained under him at Yale. He is widely regarded as one of the most influential institutional investors in history.

Exceptional by virtually any measure. Under Swensen's 36-year tenure (1985-2021), Yale's endowment grew from approximately $1 billion to $42.3 billion (at the time of his death). The endowment generated annualized returns of approximately 13.7% over his full tenure, far exceeding the roughly 9-10% return of a traditional 60/40 portfolio over the same period. Yale's endowment was the top-performing large university endowment over almost every meaningful time period. The 20-year annualized return was approximately 11.3% through 2021. The endowment outperformed its benchmark by roughly 3-4% annually over his tenure. Notably, the Yale Model struggled in 2008-2009 (GFC), with a -24.6% return in FY2009, partly because illiquid assets could not be easily sold and the endowment had to issue bonds to meet spending obligations. This was a key criticism -- the illiquidity premium is also an illiquidity risk. However, Yale recovered strongly and continued to outperform over the long term.

As an asset-allocation-focused endowment, Yale did not hold individual stocks in the traditional sense. Instead, its 'holdings' were allocations to top-tier managers: early and large commitments to venture capital (Sequoia, Greylock, etc.), private equity firms (Clayton Dubilier & Rice, Lone Star, etc.), hedge funds (Farallon Capital, etc.), and real asset managers. Yale was an early investor in many of the most successful VC and PE funds, and its track record in venture capital was particularly outstanding. The endowment also held timber and oil/gas assets directly.

Moderate relevance despite very different portfolio construction. Swensen's philosophy shares some deep similarities with ours: (1) Long-term orientation -- endowments invest with a perpetual time horizon, which aligns with our 5-10+ year holding period. (2) Emphasis on quality of partners/managers -- this is analogous to our focus on management quality. (3) Contrarian rebalancing -- buying when others sell is consistent with our floor-price approach. (4) Intellectual rigor and honesty about what works for different types of investors. However, the differences are substantial: Swensen's approach is fundamentally about asset allocation and diversification across dozens of managers and asset classes, while we run a concentrated, single-stock portfolio. He did not do individual stock analysis. His approach requires institutional scale and access (top-tier VC/PE funds have minimum investments of $25M+). The illiquidity premium thesis is interesting but not directly applicable to our liquid equity investing. His advice for individual investors -- buy index funds -- would actually argue against our concentrated approach. Best taken as intellectual inspiration rather than a tactical model.
