I first screened for stocks with a float of 2M or lower and a price of less than $5. I didn't find enough, so I increased the float to 3M I think.
I figured in this crazy market some of them would take off. They are overall profitable so far, but not making a killing.
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.
