AIM is like a Martingale in that it increases the size of the investment (bet) when losing and decreases the investment when winning. It has the same limitations as Martingale in that you can lose all your money before you achieve a win (at least there is no house limit). Thus if you choose to AIM an Enron or WorldCom, AIM will fail miserably. But if you choose to AIM a financially strong, viable business, or better yet a mutual fund or ETF, AIM will give you a workable strategy that will allow you to sleep well at night and make money.
I share Qarel's view that if AIM runs out of money, you probably should listen to AIM and not invest more.
