Depends on your tolerance for risk (someone with more knowledge of this will be along, I'm sure, to give a more definitive answer).
Bottom line, though, is you need to do some research. Relying on others - even well-intentioned others who (a) have your best interests at heart, (b) know a lot about many different types of investments and (c) aren't trying to make a buck off you - is a pretty passive way to handle your money.
Let's look at investments like anything else you buy, say, clothes or a DVD player or a car. No one can know what you like, so letting other people pick is pretty much a guarantee that you won't get what's best for you. I realize you did not word your inquiry that way, but I advise caution and a good grain of salt when it comes to any investment advice you get for free from people who don't know you.
How do you do research? A few possibilities:
(1) Go to www.fool.com
and get to know the place. That's the Motley Fool. They cover most forms of investments, such as stocks and bonds. They also have some educational content so you might want to check that out.
(2) Go to your bank. Yes, your bank, and find out what investment services they offer. Keep in mind they are going to try to sell you what they have to offer, but it is a way to get some free information.
(3) Consider the amount of risk you'd like to shoulder. What kind of risk? What am I talking about? Well, some investments carry more of a chance for profit than others, and some carry more of a chance for a total loss, even of principal, than others. Based on your age, your family (e. g. if you have kids to support), your financial goals (school, a house, etc.) and your and your family's overall health (e. g. you could find yourself dealing with nursing homes soon if your parents are elderly), think about how quickly you need to make money, how much you need, and whether you can gamble on perhaps losing all or a substantial part of it.
Finally, consider investing in something you believe in. There are funds for all sorts of things, and a lot of them have similar goals, risk factors and historical profit margins. So you might want to consider an investment fund which supports your goals, e. g. sustainable growth in the rainforest, that kind of thing. This isn't strictly necessary but it is a consideration for a number of people.
Like I said before, someone with more experience in this area will be along soon, I'm sure, but in the meantime, welcome to A2K!
