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:

    1. Vanguard Total Stock Market Index Fund, holding approximately 3600 stocks,
    2. Vanguard Total International Stock Index Fund, holding approximately 6200 stocks,
    3. Vanguard Total Bond Market Index Fund, holding approximately 8400 bonds,
    4. Vanguard Total International Bond Index Fund, holding approximately 4600 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.

Total International Stock 0.11% 0.11%

Historical returns

The portfolio has a five-year performance history. The portfolio returns reflect using investor share funds from 2014 – 2017 and admiral shares thereafter. Returns will 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:

      1. A US total market index fund
      2. An international total market index fund
      3. A US REIT index fund
      4. 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):
