I am not wanting to argue with you, but I don't agree with that assessment. You have often written that you can AIM with a #2 lead pencil and a piece of paper, but how many columns do you have to have and fill in each month (or however often)? I agree that AIM is simple enough to maintain, and that aspect is straight-forward, but the AIM mechanism is somewhat complex.
This method (ZCA) can also be done with a #2 pencil and paper with only a few columns, only it is pretty much done when you start. You set the targets for selling or additional buying before you begin the process. All you need do is set Alerts or GTC Orders once you actually buy. As Jibes illustrated on his website, you could easily keep the info on a "Post-It" note.
We basically have three market conditions, the market goes up (as it has for the past 5 3/4 years), it goes down, or it goes sideways in a range. What it will do tomorrow, we don't know, but as Bernard Baruch (I think it is attributed to him) said, "The market will fluctuate". When you begin an AIM program, you don't know what the market will do from that day forward, but you are putting $10,000 in a position and allowing AIM to work its magic from that point.
Doing the ZCA (Zero Cost Averaging) would allow you to put that same size "Core" position, but at zero cost to you, then let AIM do its work. There is a real cost associated with this idea, and it will take longer to accumulate the Core position than just putting the $10,000 in immediately, but I think it is a "feasible" method to get there.
