Three fund portfolio 2017 update

 

The three-fund portfolio, is a portfolio design consisting of three “total” market index funds, covering the US stock market, the international stock market, and the US taxable investment grade bond market. Investors were able to implement this portfolio beginning in 1997, when Vanguard introduced a total international index fund. The firm had introduced a total US stock market index in 1992, and a total US bond market index in 1987.

The 2017 returns for the portfolios constituent funds (investor class):

  • Vanguard Total Stock Market Index Fund: 21.05%
  • Vanguard Total International Stock Index Fund: 27.40%
  • Vanguard Total Bond Market Index Fund: 3.45%

Below are four portfolios with allocations modeled upon Vanguard Lifestrategy funds (click images to enlarge). The portfolios allocate 30% of the stock allocation to international stocks.

The table below provides 2017 returns for these portfolios. Note that returns for portfolios holding admiral shares would produce a return enhancement of approximately 0.10% and that a different weighting of international stocks would result in differing returns.

Year 80/20 60/40 40/60 20/80
2017 19.05% 15.15% 11.25% 7.35%

Historical returns

The following tables give return data for three-fund portfolios assuming investment in Vanguard investor share index funds. Keep in mind that past returns are no guarantee of future returns, but the history reveals how each portfolio allocation has performed over both the 2000 – 2002 and 2008 bear markets and ensuing recoveries.

Note that lower cost admiral share portfolios can add approximately +0.10% annual compound return for each allocation.
