I hear ya.... was talking with some friends on Friday and mentioned that I should have waited longer to add. I look at it like this: I missed the bottom but at least I got my shares back (the few that I flipped) and more of them than I had. High 40s sold in the 80s then back in with some lower 70s.
Keeping my core and really only comfortable taking a chance to flip a few because this thing is going to take off. It would be my luck to wait around to try and fill a lower bid and get left behind. It's the nature of the beast.
