AATC - This was a great bargain down in the 3s as late as last April with a dividend yield of around 14 percent. The move to the otc market really spooked investors. You have to wonder, though, if they kept their listing, how high the share price might be now with all the good news released recently.
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.
