What is a good asset allocation for a 25 year old?
In my opinion, the key variable for you (and others) is not age, but "vintage." Your "age" suggests that you were born in the mid-1980s, in the middle of a bull market. The most remunerative investing periods for you are likely to be in your childhood (past) and middle age (forties and early fifties). Also your, "old-old" period (around age 80, in the 2060s), if you live that long. For now, you can, and perhaps should invest cautiously, like today's 40-year olds, with a heavy emphasis on bonds. The main difference between you and them is that you can shift to stocks in about ten years, in your mid to late 30s, while they will find it harder to do so when approaching old age.
