As someone said before, as a common rule, the older you get, the more you should be investing in bonds that are more secure and steady in growth. Bonds are safer and do not go down, however they do not have as high of a growth potential as stocks. But seeing as what is going on within the market today, I would suggest you have most of your investments in bonds right now. Maybe 80-90% in bonds and the remainder in a mutual fund or stocks.
