The information on my previous post # 5366 was not complete. I should have mentioned that the $1000 that was invested on a share price of 90 was a accumulated net profit from previous operating cycles.
This alters the conclusion in that for each share price cycle:
100 to 110 to 100 to 90 and back to 100
there is a net gain of about 2,02% even if you cancel out any profits from a share price increase or skewed buying and selling in an AIM system.
I shall revise the incorrect presentation to make it more clear as to what was supposed to be demonstrated.
