With the bump in AAPL on a good quarter, and considering your initial buy in price, I would consider sellling at least some and take some profits. "Bulls make money, pigs get slaughtered" is a phrase I like to consider when I own large paper profits. Yes, AAPL is likely to have some good quarters in the future (after the holidays get on the books), but a lot of forward momentum is priced into the stock already.
Consider taking your initial buy in capital off the table, then, at least you are continuing to play the upside with "their" money. Selling more or all can not be considered a mistake, however, even if you see it go up from here. If I still belived in the company (and I don't follow it as an investment, so I am only laying out my general thought process with any stock) I would take some profits on a bump up following good news and hold some with the idea of adding to it if the price drops some. Lock in some profits.
