The late sellers were relatively small volume sellers but because it had run so much in 1 day there wasn't the buyer depth to hold the price up.
I know - I sold my 20K today at $1.32 after thinking it had run too far in 1 day. I'm hoping to buy back in lower (5-10 cents) but even if I can't I can at least feel happy that I made 80% profit on this trade.
