The following table lists 2015 total returns for various examples of “lazy portfolios”.
Some of the portfolios (Coffeehouse and Coward’s) are designed as 60/40 stock/bond portfolios. Other portfolios (Ideal and Swensen) are designed as 70/30 stock/bond portfolios. The two-fund, three-fund, and four-fund portfolios are scaled to similar stock/bond allocations. The returns are derived from investments in investor share class Vanguard index funds. Lower cost admiral share class funds would add approximately +0.10% to returns. Detailed descriptions of each portfolio’s annual returns are linked.

The following tables provide historical portfolio returns. Keep in mind that past performance does not predict future performance.
The coefficient of variation statistic is a simple measure of risk adjusted return (standard deviation divided by the mean return.) The the lower the ratio of standard deviation to mean return, the better your risk-return trade off.
