I hear ya. I bought PLKC at .083 and .088, there was a bump up to .16 I think, and I didnt' sell, the rest is history. I did however buy back in at .017, and I am not up on my PLKC position. I'm up only about 40 bucks, but I have considered my previous losses as never coming back. So, in a strange way, I am up thousands now.
I had a ton of sirius that I sold on that big climb up to nine. I made money, but I sold way to early, I sold around 5.50, lost out on all that potential gain.
It works both ways, but you are always better selling early and taking a nice profit, even though you could have sold for more the next day.
