What is the Yale endowment model?
The Yale model is a long-term, equity-oriented portfolio spread across many asset classes and run through external managers. Yale's Investments Office says the strategy was pioneered by David Swensen and Dean Takahashi and "prioritizes partnerships with the best investment managers" (Yale Investments, FAQ).
First, equity orientation: an institution that targets spending of 5.25% a year and wants to preserve purchasing power needs high returns, and its exposure to inflation pushes it away from fixed income (2025-2026 Financial Report, PDF pp. 18-19). Second, diversification, which the same report says "allows the construction of portfolios with superior risk and return characteristics".
Third, illiquidity: the 2015 report says the endowment's long horizon "is well suited to exploit illiquid, less efficient markets" such as venture capital, buyouts, timber and real estate (The Yale Endowment 2015, PDF p. 9). Fourth, active management where prices are least efficient, since alternatives offer "an opportunity to exploit market inefficiencies through active management".
The model also includes rules on risk. In its September 2020 release, Yale stated a target minimum of 30% in market-insensitive assets (cash, bonds and absolute return) and sought to limit illiquid assets to 50% of the portfolio (Yale News, 24 September 2020).
What is Yale's asset allocation today?
Yale has not published an asset-class table since its fiscal 2021 targets, released in September 2020. Those targets are the most recent dated allocation Yale itself has disclosed.
Targets for the fiscal year to 30 June 2021: absolute return 23.5%; venture capital 23.5%; leveraged buyouts 17.5%; foreign equity 11.75%; real estate 9.5%; bonds and cash 7.5%; natural resources 4.5%; domestic equity 2.25%. Source: Yale News, 24 September 2020, "Asset allocation"; chart data (CSV). These are policy targets, not actual holdings, and they predate the 2025-2026 secondary sales. By our arithmetic, the four illiquid classes add up to 55% of target, above the 50% limit stated in the same release.
Later disclosures are qualitative. Yale's 2025-2026 Financial Report says "roughly 97% of the endowment pool is invested in assets expected to produce equity-like returns, through domestic and international securities, real assets, and private equity" (PDF p. 19). The 2024-2025 report put the same figure at roughly 91% (PDF p. 19); neither report gives weights by asset class. Its 2022 and 2024 news releases list the asset classes as public equities, marketable alternatives, leveraged buyouts, venture capital and real assets, without weights (Yale News, 25 October 2024).
Yale's Form 13F is no shortcut. Yale says a company on its 13F usually comes from a manager's liquidating distribution or a gift, and that index funds and ETFs there are used to rebalance the endowment (Yale Investments, FAQ). A 13F mainly lists US-listed equities and certain listed options, is filed up to 45 days after quarter end, and excludes cash, most bonds, shorts and private funds, so it says almost nothing about an endowment held mainly in private funds.
How did Yale move from stocks and bonds to alternatives?
In 1985, 80% of Yale's endowment was committed to US stocks and bonds; by fiscal 2015, Yale's targets called for 12.5% in domestic marketable securities. The 2015 report describes the move "away from a conventional portfolio model dominated by domestic equities and bonds" from the mid-1980s (PDF p. 5).
| Asset class | June 2015 actual | June 2015 target | FY2021 target |
|---|
| Absolute return | 20.5% | 21.5% | 23.5% |
| Venture capital | 16.3% | 14.0% | 23.5% |
| Leveraged buyouts | 16.2% | 16.0% | 17.5% |
| Foreign equity | 14.7% | 14.5% | 11.75% |
| Real estate | 14.0% | 13.0% | 9.5% |
| Natural resources | 6.7% | 8.5% | 4.5% |
| Fixed income and cash | 7.7% | 8.5% | 7.5% |
| Domestic equity | 3.9% | 4.0% | 2.25% |
Sources: The Yale Endowment 2015, PDF p. 8 (fixed income 4.9% plus cash 2.8% for June 2015); Yale News, 24 September 2020. The June 2015 target column reflects policy changes Yale's Investment Committee adopted that month.
Between 2015 and 2021 the main shift went into venture capital, while real estate, natural resources, foreign equity and US stocks shrank. Matt Mendelsohn, appointed chief investment officer in August 2021, was then the director responsible for venture capital assets "comprising more than 25% of Yale's total endowment" (Yale News, 24 August 2021). He succeeded Swensen, who died in May 2021 after a nine-year battle with cancer and had led the endowment for more than 35 years.
Yale reported a 26.3% return net of fees for the year to 30 June 2026, and 11.7% a year over the decade to that date. The gain came to $11.3 billion, and after $2.2 billion of distributions to the operating budget the endowment was valued at $54.5 billion on 30 June 2026 (Yale News, 27 October 2026).
Yale says the ten-year figure beat the median college and university endowment by an estimated 1.6 points a year and a typical 70/30 stock and bond portfolio by 2.7 points a year. Yale's audited 2025-2026 Financial Report puts endowment net assets at approximately $53.3 billion on 30 June 2026, an accounting measure that differs from the $54.5 billion in the news release (PDF p. 18).
The same report says the decade's 11.7% a year added $14.3 billion of value relative to Yale's composite passive benchmark. A year earlier it reported 11.1% for fiscal 2025, with the endowment at $44.1 billion, and 9.4% a year over the decade to June 2025 (Yale News, 24 October 2025). Over the 20 years to 30 June 2024, it reported 10.3% a year (Yale News, 25 October 2024). Over the 30 years to June 2015, the figure was 13.9% a year (2015 report, PDF p. 5).
Yale's fiscal 2025 release says that year trailed public indices, as outperformance in several asset classes was tempered by underperformance in leveraged buyouts and, above all, real estate. A year earlier, chief investment officer Matt Mendelsohn said that, given Yale's private-asset allocation, "we expect to lag during periods of strong public market performance". The fiscal 2026 release gives no asset-class results, allocation or comparison with public indices.
Return methods differ across asset classes. Yale uses time-weighted returns for marketable assets and dollar-weighted internal rates of return for buyouts, venture capital, real estate and natural resources (Yale News, 2020, note 1). Private-asset values also rely on manager estimates of net asset value, which update less often than market prices.
Why is Yale selling private equity stakes?
Yale's audited financial statements give no reason for the sale; they record only that on 30 June 2025 "the university completed a sale of investments", and the 2025-2026 report adds that the resulting receivable "was collected in fiscal year 2026". The 30 June 2025 investment table shows an investment receivable of $1.04 billion, and the 30 June 2026 table has no such line (2025-2026 Financial Report, PDF pp. 37-38). Yale does not name the buyers or the size of the sale there.
On 25 September 2026, Secondaries Investor reported that HarbourVest had bought into a roughly $1 billion Yale portfolio sale, following a 2025 deal of $3-4 billion priced in the mid-90s per cent of net asset value (Secondaries Investor). We did not find a Yale publication confirming those sale sizes.
The tax backdrop changed in the same period. Yale's 2025-2026 Financial Report states that the One Big Beautiful Bill Act, enacted on 4 July 2025, raised the tax rate on its net investment income from 1.4% to 8.0%, effective for fiscal 2027, which began on 1 July 2026 (PDF p. 34).
In October 2026, Yale's provost and senior finance officers estimated that the tax will cost about $350 million a year, a cost that will grow over time (Fall 2026 Financial Update). Yale puts the tax liability associated with the fiscal 2026 gain at roughly $900 million (Yale News, 27 October 2026).
The audited statements record a deferred excise-tax liability of $1,280.8 million at 30 June 2026 and excise-tax expense of $1,170.6 million for fiscal 2026, of which $1,009.5 million is attributed to the higher rate (PDF p. 34). The news release and the statements use different measures, and Yale does not reconcile the two figures.
An endowment that targets spending of 5.25% a year, pays more tax and last published 55% illiquid targets has less room when private-fund distributions slow. Harvard's endowment, with 46% in private equity at 30 June 2026, is examined in our Harvard endowment study.
What portfolio did Swensen recommend for individual investors?
In Unconventional Success (Free Press, 2005), Swensen proposed six asset classes for individuals: 30% US stocks, 20% REITs, 15% foreign developed-market stocks, 5% emerging-market stocks, 15% US Treasury bonds and 15% inflation-protected Treasuries. The Yale Alumni Magazine reproduced that allocation in a March/April 2009 interview (Yale Alumni Magazine).
Unconventional Success (2005): domestic stock funds 30%; REITs 20%; foreign developed-market stock funds 15%; US Treasury bonds 15%; Treasury inflation-protected securities 15%; emerging-market stock funds 5%. Source: Yale Alumni Magazine, March/April 2009, "Swensen's recipe for investing"; chart data (CSV). The chart shows the book allocation, not the 2009 revision described below. It contains no private equity, hedge funds or corporate bonds.
The same article reports a revision: in 2009 Swensen suggested 15% in REITs and 10% in emerging-market stock funds.
He told the magazine to use index funds "because they're transparent, understandable, and low-cost", to set targets and rebalance, and that bond investors should hold only "full faith and credit" securities. He said individuals without Yale's resources should not try to pick stocks or pay someone to do it.
Popular "Yale Endowment Portfolio" ETF lists show this individual mix, not Yale's. One such list labels 30% VTI, 20% VNQ, 15% VEA, 5% EEM, 15% IEI and 15% TIP as the "David Swensen Yale Endowment Portfolio" (Lazy Portfolio ETF). Yale's own fiscal 2021 targets had 2.25% in US stocks, 7.5% in bonds and cash and 64.5% in absolute return, venture capital and buyouts.
Does the Yale model make a portfolio more resilient?
The Yale model diversifies managers and markets, but its equity exposure and illiquidity remain substantial. Its last published illiquid targets totalled 55%, and the 2025-2026 report describes roughly 97% of the pool as equity-like. Yale's 2015 report, PDF page 8 explicitly describes using mean-variance analysis alongside market judgement to assess allocations. The report also acknowledges difficulties incorporating liquidity and rare events.
Copio's research objective is maximum expected long-term geometric growth within the investor's constraints. A favourable mean-variance profile does not by itself establish that result, and smoother private-asset valuations do not create gains available to spend during a crash. Diversification can improve compounding; we also evaluate whether cost-controlled convex protection can support a growth portfolio more effectively than reducing productive exposure. Our resilient portfolio allocation guide separates these mechanisms and the evidence each requires.
What can an individual investor learn from David Swensen?
Yale's approach depends on a permanent horizon, professional staff and access to private managers. Swensen's individual portfolio uses liquid index funds. Warren Buffett's 90/10 instruction reaches a similar conclusion on low-cost index funds, with a far simpler mix.
Yale's 26.3% gain in fiscal 2026 came after a year in which it trailed public indices, which is a reminder to judge any allocation over a full decade rather than a single year.

What you can do now
The Yale model and Swensen's index-fund mix share three disciplines that any portfolio can be checked against: no single asset class dominates, liquidity is planned, and costs are known.
- Measure your largest asset class. In Swensen's individual mix no class exceeds 30%; in the Copio app preview, the allocation view shows your weights by asset class across accounts, so you can see whether one class dominates and decide whether that is deliberate.
- Write down what you could sell within a week. List each holding as same-week, within a year or locked (for example a private fund, a pension or a home), then compare the first group with a year of planned spending and any known large expense.
- Name the job of each bond holding. Government bonds and inflation-linked bonds were Swensen's crisis reserve; corporate and high-yield bonds add income with credit risk, so check which of the two your bond funds hold in their factsheets.
- Add up what your funds cost each year. Multiply each fund's ongoing charge by the amount held; Copio's ETF comparison shows the charge of each fund it covers next to its exposure.
- Set a written target and a rebalancing rule. A target weight per class and a band, such as five points either side, turns Swensen's rebalancing discipline into a rule you can follow without forecasting markets.
FAQ
What is the Yale endowment model?
The Yale model is the investment approach pioneered by David Swensen and Dean Takahashi at Yale's endowment, which Swensen led from 1985. Yale describes it as long-term, equity-oriented and diversified across asset classes, built on partnerships with external managers. In practice it means large allocations to venture capital, leveraged buyouts, absolute return and real assets, and very little in domestic stocks and bonds.
What is Yale's current asset allocation?
Yale's last published asset-class targets, for the fiscal year to 30 June 2021, were 23.5% absolute return, 23.5% venture capital, 17.5% leveraged buyouts, 11.75% foreign equity, 9.5% real estate, 7.5% bonds and cash, 4.5% natural resources and 2.25% domestic equity. Yale has not published a target table since. Its 2025-2026 Financial Report, covering the year to 30 June 2026, says roughly 97% of the endowment pool is invested in assets expected to produce equity-like returns, up from roughly 91% in the 2024-2025 report.
What portfolio did David Swensen recommend for individual investors?
In Unconventional Success (2005), Swensen proposed 30% US stock funds, 20% REITs, 15% foreign developed-market stock funds, 5% emerging-market stock funds, 15% US Treasury bonds and 15% inflation-protected Treasuries, held in low-cost index funds and rebalanced. In a 2009 Yale Alumni Magazine interview he suggested 15% in REITs and 10% in emerging markets.
How has the Yale endowment performed?
Yale reported a 26.3% return net of fees for the year to 30 June 2026, with the endowment at $54.5 billion after $2.2 billion of distributions to the operating budget. Over the ten years to 30 June 2026 it returned 11.7% a year, an estimated 1.6 points a year above the median college and university endowment. The year before, it returned 11.1%, which trailed public indices.
Is the Yale endowment model a conservative portfolio?
Yale's 2015 report describes mean-variance analysis alongside market judgement, while its 2025-2026 Financial Report calls roughly 97% of the pool equity-like. Diversification can improve compounding, but neither a smoother valuation series nor an efficient risk-return profile establishes cost-effective crash protection. Copio evaluates allocations against expected whole-portfolio geometric growth after costs and liquidity constraints.
