I don't know how much more downside there is but I believe this is a great price. If I go out and buy a TV today and am happy with the price and next week I find I could have got it cheaper, am I still happy with the TV. Yes. Sometimes you might take it back to the store and see if you can get the cheaper price but I have not done that much.
If I bought 5000 shares today, I would still have got a good price. It is definitely cheaper then what I paid before and if I see something later and want some money at least I got some cheaper shares to sell. I'm long just as you are.
