I do have to argue with one point: that the younger you are the more aggressive you should be with your investments. While I think this is true once you start making a steady income, I don’t know that it is when you’re just finishing highschool and have very little money to begin with.
Look at it this way: $1500 is a LOT of money for most 18 year olds. $1500 is not so much when you start making a steady paycheck; not that it’s a small sum, but it is more easily replaceable. When you invest money at that age, you are giving up the use of a proportionately more important amount of money. In other words, you’re giving up money now (when you need it) to have that money in the future, when you’ll need it less.
Rationally, of course, you could make the argument that in that case, since you’re giving up the use of the money anyway, it might as well go into the highest-risk, highest payout investments possible. The potential for it to yield large dividends in time for him to start a job and maybe buy a house, etc.
In someone that young, however, I’d really prefer to build the habit of saving and investing, rather than worry so much about getting big returns. After all, if he loses his money in four years (a definite possibility with high-risk investments), it could sour him on investing in the future. After all, it would seem like the money was lost for no reason.
Instead, I really suggest investing in something like the Vanguard Total Stock Market Index. Reasonable returns, low fees… and you can earmark the money for a vacation or whatever you want after you graduate college. It’s also a great starting long-term investment.[/quote]
I think you’re correct in that I don’t think age has anything to do with it – it’s the time horizon of when you think you would use the money.
From these posts, I’d say the assumption should be that he would use the money on a house down payment within 5-10 years, which would argue for a somewhat conservative mix of stocks and bonds – say 60/40 stocks/bonds, with stock 50/50 between U.S. and international total index ETFs and bonds with some broad bonds and some in TIPS, say 80/20 broad to TIPS.
Also, interestingly, there has been some academic focus recently on whether it makes sense to take big risks early on even in a long term investment – the idea being that, much as the small gains get bigger over time because of compounding, a large setback in the first five years could really hurt long-term returns.
