Personally, I want to see a blow-off rally on big big volume before I take a lot, if not all, off the table. It has been a good run..I am not quite sure it's over yet.
I am up nearly 1,000% on some positions I took a long time ago. That's a lot, and it's not something I am going to be confortable with myself if those gains evaporate because I got greedy (a common mistake).
