I use Scott Burn's 10-speed portfolio (
AssetBuilder Inc. - Registered Investment Advisor- Couch Potato Results) which uses 10 equally weighted funds. Scott is a writer for USAA's magazine. Almost all of his recommendations are Vanguard index funds. Here is what I own:
10% VTSMX (Vanguard Total Stock Market Index)
10% VIPSX (Vanguard TIPS)
10% BJBIX (international growth managed fund)
10% BWX (international bonds ETF)
10% VGSIX (Vanguard REIT Index)
10% VDE (Vanguard Energy ETF)
10% VIVAX (Vanguard Value Index)
10% VISVX (Vanguard Small Cap Value Index)
10% VEIEX (Vanguard Emerging Markets Index)
10% VTRIX (Vanguard International Value)
I hold BWX and BJBIX in another account so that is why they are not Vanguard mutual funds. I use VDE because I cannot make the minimums (yet) on the VGENX (Vanguard Energy fund).
This works out to about 80% equities, 20% bonds, so it is fairly aggressive. The 80% equities is made up of 30% international, 15% small caps, 25% large caps, and 10% REITs.
