Hi Jibes,
I do think that you would need to run a test over a full cycle. In the Cisco case you stop when the share price has not yet recovered to its old high. But it is the premise of AIM that a stock WILL recover (otherwise your stock selection was wrong!).
After all, AIM did end up with more shares, thus the potential to beat New-AIM is there.
BTW: It looks more like XDEV than AIM to me, maybe you should call it New-XDEV? (VBG)
(XDEV uses the deviation from a SMA, you use the deviation from the last buy/sell)
