UUU - I sold some I bought this morning, also. It's showing big-time strength on a horrible market day. I'm still holding a goodly amount, since like you, I believe a big upward spike could happen at any time with the low float and that just-reported 15 cent quarter.
I have seen lots of $1 stocks with strong earnings and solid balance sheets triple, quadruple and more, but I have yet to see one go below zero.
