Hi Hook
Aim solves a number of problems for investors EXCEPT and individual company going bust.
ETFs, CEFs, and no - load mutual funds (Vanguard hint hint) solve that problem.
First: decide if you want to diversify by style or industry.
Second: make a list of funds that you want to own that will meet that goal. Somewhere between 5 (large, small, foreign,REIT , bond) and 10.
Third: Either buy them all or buy them gradually as you have more funds available.
Fourth: Stick with the plan you start with and don't change it because you get nervous or on a whim.
The main benefit of AIM is that it takes the emotion out of investing. Allow it to do that. Any changes you make to your original plan are likely to be emotional.
If you think you can make 1 or 2 or 5% more per year by making some change you probably won't or it will be by increasing risk.
