I have only invested in 401ks and IRAs, and kick myself that I never did anything like this!
The advice this guy gives is similar to other articles that I have read recently.
However, if you have the chance to invest in a 401k, or do not plan to use the money any time soon - try a Roth IRA. You can invest in similar funds.
I recently reviewed the options my company offers and saw that any of the fund choices would have been better than the money market fund I had camped some money in. The point here is that these funds did do quite well in their respective categories, so some intelligence has gone into the choice of offerings, and they were much better than the 2% quoted in the article.
