Does Meb Faber's Ivy Portfolio work?

By Jeffrey Lin · Published 2026-08-24 · Updated 2026-08-24

The Ivy Portfolio, from Meb Faber, is the buy-and-hold version of the endowment approach used by Yale and Harvard: an equal, five-way split across US stocks, foreign stocks, bonds, commodities, and real estate. The idea is that spreading across very different asset classes smooths the ride and adds protection stocks and bonds alone don't have.

From Jun 1996 to Jul 2026, a yearly-rebalanced Ivy Portfolio portfolio returned 7.8% per year with a maximum drawdown of -43.1% — versus 10.2% and -50.8% for S&P 500 (SPY) alone. It gave up some return for materially lower risk, producing a higher Sharpe ratio (0.73 vs 0.71). $10,000 grew to $95,419 (vs $188,208 in the S&P 500).

Growth of a $10,000 investment, Jun 1996–Jul 2026. The Ivy Portfolio line rises more slowly than the S&P 500 but with visibly shallower dips — the trade-off the strategy is designed to make.

What an investor actually experiences: drawdowns

Drawdown (underwater curve): Ivy Portfolio vs S&P 500 (SPY)Worst peak-to-trough decline was -43.1% for the Ivy Portfolio portfolio versus -50.8% for S&P 500 (SPY).-50%-40%-30%-20%-10%0%19962000200420082012201620202024S&P 500 (SPY)Ivy Portfolio
Decline from the prior peak — the "underwater" curve.

A drawdown is the stretch of time when your account is worth less than it was, with no way to know when it will recover. Ivy Portfolio's worst decline was a severe -43.1% — almost as deep as the S&P 500's own -50.8%. How long the pain lasted matters just as much: it spent as long as 32 months (about 2.7 years) below a prior high, versus 74 months (6.2 years) for the S&P 500.

A fall of -43.1% is the kind that tests conviction. If you needed this money for a house, a child's tuition, or retirement during such a slump, you could be forced to sell near the bottom — which is why money you will need within a few years usually belongs somewhere less exposed than this.

Here is what those figures mean for a real saver. CAGR is the smoothed annual growth rate: at 7.8% a year, Ivy Portfolio turned $10,000 into $95,419 over about 30 years, versus $188,208 for the S&P 500. Volatility (11.1% vs 15.3%) is how much the ride bounces from year to year. The Sharpe and Sortino ratios measure return earned per unit of risk (higher is better). And the maximum drawdown — the deepest peak-to-trough fall — is the number that decides whether you can actually stay invested.

Over this particular window the diversification roughly broke even: Ivy Portfolio earned about the same risk-adjusted return as the S&P 500 (Sharpe 0.73 vs 0.71) while trailing on raw growth. Its case rests on protecting against risks — a prolonged US-stock slump, an inflation shock — that this stretch did not deliver.

Figures are computed from monthly adjusted closing prices over Jun 1996–Jul 2026. Drawdowns are measured at month-end and so understate intra-month extremes.

Methodology

The two instruments

VTI — Vanguard Total Stock Market ETF
Every US stock, large and small — the core growth holding.
VEU — Vanguard FTSE All-World ex-US ETF
Every non-US stock — developed and emerging markets in one fund.
IEF — iShares 7-10 Year Treasury Bond ETF
Intermediate US government bonds — a steadier, less rate-sensitive anchor.
DBC — Invesco DB Commodity Index ETF
A basket of commodities (energy, metals, agriculture) that tends to rise with inflation.
VNQ — Vanguard Real Estate ETF
US real-estate investment trusts (REITs) — property income that behaves a bit differently from stocks.

Advantages

Broad, true diversification
Five distinct asset classes — including commodities and real estate — mean the whole portfolio rarely falls at once, and it carries inflation defenses a stocks-and-bonds mix lacks.
Endowment logic, retail cost
It captures the spirit of how large endowments invest, using cheap, liquid ETFs any investor can hold.

Disadvantages and risks

Commodities have been a persistent drag
Broad commodities can lose value for years between inflation spikes, weighing on returns during calm, low-inflation periods.
Five equal slices is a blunt rule
Equal-weighting ignores that some assets are far riskier than others, so the stock and commodity slices dominate the ups and downs.

Frequently asked questions

What is the Ivy Portfolio?
An equal 20% split across US stocks, foreign stocks, intermediate bonds, commodities, and real estate (REITs), rebalanced yearly — Meb Faber's simple take on the endowment model.
Is the Ivy Portfolio a good strategy?
It offers genuine multi-asset diversification and inflation protection, which shines in turbulent decades. Its weak spot is long calm stretches, when the commodity slice can drag on returns.
How is the Ivy Portfolio different from a 60/40?
It adds foreign stocks, commodities, and real estate that a 60/40 leaves out — trading some simplicity for protection against inflation and US-only risk.
