Hi Toofuzzy, I've been using the date of the first PUT as the starting point for calculating return rate, as you suggest. It just seems a bit dingy given that one has no costs at that point and might not for up to 90 days, that's why I was asking.
As to results, on one position that is 198 days since selling the put; the total return, including dividends on all of the shares, including the extras bought for AIMing when the put was assigned, is now $3787, 55.47%.
Mind you, that includes the shares still held which could drop significantly should the market tank but then AIM would kick in so that would help maintain the gain, which is why, it seems to me, that the combo of options and AIM is a good idea.
I have a hard time believing that this type of return would be typical so I'm being cautious about choosing the next set to try. I think I'll just paper trade for quite a while before doing an actual trade.
