The Ivy Portfolio: Endowment-Style Investing
Meb Faber's Ivy Portfolio distills the endowment investing of Yale and Harvard into something a retail investor can run: five equally weighted asset classes, broadly diversified, optionally with a simple trend overlay.
Don't have time? Here's what you need to know:
- 1The Ivy Portfolio replicates endowment-style diversification with five equally weighted ETF sleeves at 20% each.
- 2The five asset classes are U.S. stocks, foreign stocks, bonds, real estate, and commodities or real assets.
- 3An optional 200-day moving-average overlay aims to cut bear-market drawdowns but adds trading, taxes, and whipsaw risk.
- 4The 20% commodity sleeve can be a long-run drag; a four-asset version trades some inflation protection for simplicity.
Endowment Investing, Stripped Down
The Ivy Portfolio comes from Meb Faber and Eric Richardson's book of the same name, which studied how the large university endowments at Yale and Harvard invested. Those endowments, under managers like David Swensen, earned strong long-run returns by spreading money broadly across many asset classes rather than concentrating in domestic stocks and bonds, and by leaning into real assets and global diversification.
Most of what the endowments do, illiquid private equity, venture capital, hedge funds, is out of reach for ordinary investors. Faber's insight was that the spirit of the approach, broad diversification across distinct asset classes, can be replicated cheaply with index ETFs. The Ivy Portfolio is that replication: an accessible, low-cost version of the endowment model.
Five Equally Weighted Asset Classes
The simplest Ivy build is five equally weighted sleeves of 20% each: U.S. stocks, foreign stocks, bonds, real estate, and commodities. The point of equal weighting across five genuinely different asset classes is that each responds to different economic forces, so the portfolio is not dependent on any one of them.
An ETF implementation uses VTI for U.S. stocks, VXUS for foreign stocks, BND for bonds, VNQ for real estate, and a broad commodity fund (often including gold via GLD) for the commodities sleeve. The combination of real estate and commodities is what gives the Ivy Portfolio its real-asset, inflation-aware character, distinct from a plain stock-and-bond portfolio.
| Asset class | Weight | Example ETF |
|---|---|---|
| U.S. stocks | 20% | VTI |
| Foreign stocks | 20% | VXUS |
| Bonds | 20% | BND |
| Real estate | 20% | VNQ |
| Commodities / real assets | 20% | broad commodity fund or GLD |
The Optional Trend-Following Overlay
Faber's research added an optional tactical layer on top of the buy-and-hold version. The rule is mechanical: hold each asset class only when its price is above its long-term moving average (often the 200-day or 10-month average), and move that sleeve to cash when it falls below. The aim is to sidestep the worst of major bear markets while still participating in uptrends.
The overlay is genuinely optional and adds complexity, trading, and potential tax events that the plain buy-and-hold version avoids. It can reduce large drawdowns in trending bear markets, but it also generates whipsaws and can lag in choppy or sharply V-shaped recoveries. Many investors run the simpler static five-asset version, accept the full volatility, and skip the timing rules entirely. Both are legitimate; the static version is far easier to stick with.
Important: The trend overlay requires disciplined monthly checks and trading, generates taxable events in a taxable account, and can whipsaw in volatile markets. If you cannot follow the rules mechanically every month, the static buy-and-hold version is the safer choice.
Strengths, Limits, and Who It Suits
The Ivy Portfolio's strength is genuine diversification across five distinct asset classes, including real assets that many simpler portfolios ignore. That breadth can smooth returns and provide some inflation protection through the real estate and commodity sleeves. It suits investors who want an endowment-style, all-asset approach without paying for an advisor or chasing illiquid alternatives.
Its limits are worth weighing. Commodities have historically delivered low or negative real returns over very long periods and can be a persistent drag, so a 20% commodity weight is a meaningful bet that may not pay. The portfolio is also more complex than a three-fund portfolio for diversification benefits that are real but modest. Rebalance the static version once a year, hold the income-heavy sleeves in tax-advantaged accounts, and decide up front whether you have the discipline for the trend overlay before committing to it.
Tip: If you find five sleeves plus a timing rule overwhelming, a static four-asset version (stocks, foreign stocks, bonds, real estate) captures most of the diversification with less complexity and no commodity drag.
Frequently Asked Questions
What is the Ivy Portfolio?
It is Meb Faber's accessible version of how the Yale and Harvard endowments invest: broad diversification across five equally weighted asset classes (U.S. stocks, foreign stocks, bonds, real estate, and commodities), built cheaply with index ETFs instead of the illiquid alternatives endowments actually use.
What ETFs make up the Ivy Portfolio?
A common build is 20% each in VTI (U.S. stocks), VXUS (foreign stocks), BND (bonds), VNQ (real estate), and a broad commodity fund or GLD for the real-asset sleeve. The exact funds vary, but the structure is five equally weighted, genuinely different asset classes.
Do I have to use the trend-following overlay?
No. The 200-day moving-average timing rule is optional. It aims to reduce big bear-market drawdowns but adds trading, taxes, and whipsaw risk. Many investors run the static buy-and-hold version, which is simpler, more tax-efficient, and far easier to stick with over the long run.
Is the 20% commodity sleeve a problem?
It can be a drag. Commodities have historically delivered low or negative real returns over very long periods, so a fifth of the portfolio in commodities is a meaningful bet that may not pay off. Some investors prefer a four-asset version without commodities, accepting slightly less inflation protection for a cleaner, lower-drag portfolio.
