Hi Tom, Re AAPL. I had 3 consecutive AIM sells in Jan, May, and in June, then as the stock went up further I incremented the PC (same effect as Vealing it) and let it ride up without selling. This was partly because I wanted a larger position in the stock, partly because the stock already generated enough cash, and partly because the stock reacted positively to earnings report and I thought it was going further up (essentially overriding AIM).
I used similar tactic with AMZN.
