Myst, Anybody, On SYMC , AIM or not to AIM?
I have made the check on that AIM spread sheet you send me. As I mentioned in my e-mail, I can not determine if it contains an error or not, but the yield of -1,4% for the 191 day run could almost not be right.

Example parameters

66% - 33% split (Stock Value - Cash)
Starting Date 1/2/02 - 7/13/02
Here are the results:
X_DEV = +51.77%
AIM = (-1.4%)
I even tried to tweak AIM as best I could to yield the best return. I set the SAFE to 5% instead of the BTB 10% and also raised the minimum buy shares to 40 and sell shares to 30 so that AIM could get the best buy and sell prices. Didn't help much as you can see below:
I have run the SYMC data through a Vortex AIM spread sheet and the yield is 49 percent for the optimised parameters, for the 191 day run. For the parameter settings that were optimised for another stock the yield was about 16 %. This shows how important it is that AIM structures are optimised for each stock.
Somebody suggested that AIM is not good for daily stock prices. I do not agree with that. The Daily Prices are no problem for AIM. The frequency of entering data in an AIM has no effect on its performance. The AIM does not react to dates! It reacts to prices. If the prices swing wildly enough AIM would make a deal every day!!! The performance on the SYMC proves that: very few trades are generated.
The results that are shown by Myst for the AIM performance might not be representative for AIM structures in general as many AIMers have adapted their system, as I have done. Perhaps it is more appropriate that X_DEV is compared to the Buy and Hold method only, because this reference has a standard interpretation.
There many AIM Variants, and to compare X_DEV the most basic of all AIMs does no justice to the AIMs that exist. I suggest also that X_DEV can best be compared to the B and H method only: The difference is then the greatest and the most effective for marketing purposes.
