My apologies - I read too fast.
It sounds like you'll want to consider something like a Mutual Fund, which are usually based on a whole mix of equities. Some Mutual Funds are even nothing more than investments in other Mutual Funds.
I think this is really something you're going to need a specialise investment broker to advise upon - but do watch out for fees and be very clear on tax liabilities.
Sorry that doesn't sound very helpful - not sure how much information I can give here.
