Core four portfolios are simple indexed portfolios that allocate assets across four asset class mutual or exchange-traded funds.
The 2015 performance of the core four portfolio based on Vanguard’s life strategy and target date portfolio allocations, and of Rick Ferri’s core four portfolio are tabulated below. The portfolios assume using investor share funds. Using lower cost admiral shares adds approximately 0.10% added return.
Vanguard core four portfolios
Starting February 6, 2013, Vanguard began offering investors four fund portfolios, invested in four “total market” index funds through the firm’s series of low cost target date and target risk (called LifeStrategy) balanced index funds. Furthermore, the firm’s on-line portfolio allocation tools now suggest similar four fund allocations.
The Vanguard target date and LifeStrategy portfolios allocate investments across the following asset class index funds:
- Vanguard Total Stock Market Index Fund, holding approximately 3700 stocks,
- Vanguard Total International Stock Index Fund, holding approximately 6000 stocks,
- Vanguard Total Bond Market Index Fund, holding approximately 7800 bonds,
- Vanguard Total International Bond Index Fund, holding approximately 4000 bonds.
Vanguard allocates 40% of a portfolio’s stock allocation to international stocks and allocates 30% of a portfolio’s bond allocation to international bonds. The charts below show the portfolio allocations for four stock/bond allocation splits. (Click charts to enlarge).
The four portfolio constituents have the following expense ratios.
|Fund||Investor shares||Admiral shares||ETF shares|
|Total International Stock||0.19%||0.12%||0.13%|
|Total International Bond||0.17%||0.14%||0.15%|
The portfolio has a two-year performance history. The portfolio returns reflect using investor share funds. Portfolios using lower cost admiral shares have an approximate 0.10% increase in annual performance. Returns will also differ for different international stock and bond allocations.
Rick Ferri Core Four
Investment author and advisor Rick Ferri proposes a four fund portfolio that adds a US equity REIT fund to a portfolio consisting of US stocks, International stocks, and US bonds.The asset allocation menu holds the following positions:
- A US total market index fund
- An international total market index fund
- A US REIT index fund
- A US total bond market fund
Rick proposes that investors first determine their bond allocation. With the remaining funds, allocate 60% to US stock, 30% to international and 10% to REITs. For example, this formula would provide the following allocations (click charts to enlarge):

The rationale for adding equity REITs to a portfolio is quite simply the size of commercial real estate as an asset class in the economy. Advice on investing in real property is as old as the ancient Talmud: “Let every man divide his money into three parts, and invest a third in land, a third in business, and let him keep a third in reserve” and as current as David Swensen, the investment manager for the Yale endowment fund, who advises investors to include commercial real estate in his model portfolio.
If you work in the real estate business, or if you are already directly own and manage real estate rental properties, you may not want or need added exposure to equity real estate.
