Be prepared for a lot of different opinions on this matter.
I’m not a financial analyst–and you should consult someone who is–but I know that answering your question depends on a lot of different factors. For instance, how much time do you have? How much risk are you comfortable with?
The stock market historically has yielded good returns on investment, but there are always down periods. Unless you invest in a “dog” stock or mutual fund, you should make a return in time, but that time period could be many years. I know this, in part, because I invested in several mutual funds just before the big crash a few years ago and lost thousands of dollars. (Had I waited a few months, I could have invested while everything essentially was “on sale.” Ah, the value of timing.)
Only recently–and through selling off a couple of those funds and investing in others–have I recouped my original investment and started to see it grow. Now, because I don’t plan on tapping into my investments for another 15 years, I’ve got time on my side to let it grow and should do fine. But if I had to cash it out today, I’d have been better off putting my money somewhere else, maybe even in a long-term CD.
Investments in less volatile vehicles, like CDs and savings accounts, generally provide less return. Right now, with interest rates for loans low (but rising), the interest rates for CDs and savings accounts are also quite low.
Remember, tax implications and inflation can really whittle down your investment. Talking to a CPA as well as a financial analyst is a good idea to better understand how these factors impact your investment.
Now, here’s something to consider: You want to save for college, which is commendable, but you may also qualify for financial aid when the time comes. In general, assets which you have to pay for college are subtracted from the total aid package that you might be offered. In other words, it’s possible that if you save a thousand dollars for college that the college might decide that rather than award you a thousand dollars (or a percentage) in aid, it expects you to use your own money.
Unless things have changed since I was in college, you must report the amounts you have in savings accounts and the like when filling out the Financial Aid Form. However, if you put that money into something less tangible on paper–such as antiques that might increase in value–you may not have to report it. Thus, you might get a bigger financial aid package while still holding onto your investment, which can be sold later. Of course, investing in such things as antiques is highly speculative and much financial aid nowadays comes in the form of loans, but it’s something to consider.
