In my case, the 75% I designated to produce income for living expenses was being AIM'd as well as the 25% invested for "growth." The income pieces were pretty slow moving but threw off enough cash to keep us in groceries, etc. The "growth" side at that time was essentially all individual stocks that were bunched into general business sector categories to be large enough to AIM as individual baskets.
I guess I was creating "ETF" sector funds before they got popular!
