I found this idea from the aritcle Beat the Market with Lazy Portfolios on the GetRichSlowly blog.
The idea is to invest in a portfolio of simple index funds. These simple investment portfolios have been outperforming the S&P for the past 6 years.
The guy that wrote about them first is Paul Farrell and his latest update on them is posted in the article
.
I'm interested in the simple 3 fund portfolio named 'Margaritaville Portfolio'. Its made of 33% each of Vanguard Inflation-Protected Securities, Vanguard Total International Stock Index VGTSX and Vanguard Total Stock Market Index. The returns have been 1yr = 10.87%, 3yr = 10.93% and 5yr = 14.45%.
