Hi Aimstudent
First: what makes you suddenly discover a security that is at a 52 week high?
Aim works best with long term holdings so they can go thru multiple market cycles. In other words, what do you want to own forever as part of a diversified portfolio?
I wouldn't start An Aim account with less than $20,000 in any one security otherwise the trades become too small.
Funds are safer than individual stocks that can and do go to zero. Then there are the deep divers that go down.....and then stay there.
Buy the time you have an s+p 500 fund, a Russell 2000 fund, a foreign fund, a REIT fund, and a long bond fund you are talking a minimum of $100,000 before you might consider more specialized funds like technology, health, mining, etc
I don't know if I answered your question or just gave you more.
If you are just starting out with modest funds I would start with a large cap fund. Then I would decide what else you want to own the rest of your life and then add one fund at a time as you have the funds.
