ok. for your age and risk tolerance, i would suggest (VGSTX) or (VWLEX). The reason i prefer vangaurd are low fees.
These are both very stable.
Or you could look up some of the t-row price retirement funds (2040 fund?) They are a little more pricey but are made up of some very solid funds.
I agree that you might want to wait untill sept or december to invest. The end of QE 2 is comming = very risky market.
GL!
