Rick Ferri Core-Four Portfolio
Advisor Rick Ferri's Core Four takes the three-fund portfolio and adds a fourth building block, real estate, for a more complete, still very simple foundation of U.S. stocks, international stocks, bonds, and REITs.
Don't have time? Here's what you need to know:
- 1The Core Four is a three-fund portfolio plus a dedicated REIT sleeve: VTI, VXUS, BND, and VNQ.
- 2Set your stock/bond split first, then carve a modest REIT slice (often ~10% of equities) out of the stock portion.
- 3REIT dividends are taxed as ordinary income, so the real estate sleeve belongs in a tax-advantaged account.
- 4It adds one fund's worth of diversification and maintenance over a three-fund portfolio and otherwise runs itself.
The Three-Fund Portfolio, Plus Real Estate
Rick Ferri is a low-cost index advocate and author who designed the Core Four as a slightly more diversified take on the classic three-fund portfolio. The argument is that publicly traded real estate behaves differently enough from broad stocks and bonds to justify its own dedicated slice, rather than relying on the small REIT exposure already buried inside a total-market fund.
The result is still a simple, four-piece portfolio that any investor can run with a handful of ETFs. It keeps the core philosophy of cheap, broad index funds while adding one extra source of diversification. For investors who feel a three-fund portfolio is too bare but a ten-fund portfolio is overkill, the Core Four is a deliberate middle ground.
The Four Building Blocks
The Core Four holds a total U.S. stock market fund, a total international stock fund, a U.S. bond fund, and a real estate (REIT) fund. A standard ETF build uses VTI for U.S. stocks, VXUS for international stocks, BND for bonds, and VNQ for U.S. real estate investment trusts.
Ferri's published versions typically devote the majority of the equity exposure to the two stock funds, a meaningful slice to bonds sized to your risk tolerance, and a smaller dedicated allocation (often around 10% of the stock portion) to REITs. The exact weights are a personal decision, but the REIT sleeve is intentionally modest; it is a diversifier, not a centerpiece.
| Building block | Example ETF | Role |
|---|---|---|
| U.S. stocks | VTI | Domestic growth engine |
| International stocks | VXUS | Global diversification |
| Bonds | BND | Stability / shock absorber |
| Real estate (REITs) | VNQ | Income, inflation-sensitive diversifier |
Why Add a REIT Sleeve at All?
Real estate investment trusts own and operate income-producing property and are required to pass most of their taxable income to shareholders as dividends, which gives REITs a relatively high yield and a return pattern driven partly by rents and property values rather than only corporate earnings. That distinct driver means REITs do not move in perfect lockstep with the broad stock market, so a dedicated sleeve can add diversification.
It is worth being honest about the limits. A total U.S. stock fund like VTI already includes REITs at their market weight, so a separate sleeve is an active decision to overweight real estate beyond that baseline. The case rests on real estate's income characteristics and its sensitivity to inflation; the counterargument is that the overweight adds complexity and a tax wrinkle for limited additional benefit. Reasonable investors land on both sides.
Important: REIT dividends are mostly taxed as ordinary income rather than at the lower qualified-dividend rate. Hold the REIT sleeve in a tax-advantaged account like an IRA to avoid an unnecessary tax drag.

Weighting and Maintenance
Set your stock/bond split first, based on age and risk tolerance, exactly as you would with a three-fund portfolio. Then carve the REIT slice out of the equity portion (a common choice is roughly 10% of stocks) and split the rest between U.S. and international, often leaning domestic with 60-80% of equities in U.S. stocks. As with any lazy portfolio, the weights matter more than the precise funds.
Maintenance is the same low-effort routine: contribute regularly, place bonds and REITs in tax-advantaged accounts for efficiency, and rebalance once or twice a year when any slice drifts more than a few points from target. The Core Four asks for one extra fund's worth of attention compared with a three-fund portfolio and otherwise runs itself.
Tip: If the extra fund feels like too much, a three-fund portfolio is a perfectly good default. The Core Four is for investors who specifically want a dedicated real estate tilt.
Frequently Asked Questions
What are the four funds in Rick Ferri's Core Four?
A total U.S. stock fund, a total international stock fund, a U.S. bond fund, and a real estate (REIT) fund. A common ETF build is VTI, VXUS, BND, and VNQ. It is essentially a three-fund portfolio with a dedicated real estate sleeve added.
How is the Core Four different from a three-fund portfolio?
The only difference is the fourth fund: a dedicated REIT allocation. A three-fund portfolio already holds REITs at market weight inside its total stock fund, so the Core Four is a deliberate choice to overweight real estate for its distinct income and inflation characteristics.
How much should I put in the REIT sleeve?
The REIT allocation is intentionally modest, often around 10% of the equity portion of the portfolio. It is a diversifier, not a centerpiece. Because REIT dividends are taxed as ordinary income, hold the sleeve in a tax-advantaged account to avoid an unnecessary tax drag.
Is the Core Four better than a three-fund portfolio?
Not definitively. Adding a REIT sleeve can improve diversification because real estate has a somewhat distinct return driver, but it also adds complexity and a tax consideration for a modest benefit. Both are sound, low-cost portfolios; the Core Four simply suits investors who specifically want a real estate tilt.
