Mostly small regional players, none of them are publicly traded in USA. One company Waterfurnace trades in Toronto, Canada. Waterfurance trades at more than 35 times 2007 earnings, and recently trading at all time highs, is also one of the best performing stocks on Torono Exchange over past few years. However, LXU, market leader, is being ignored becasue it trades on AMEX and trades at less than 10 p.e.
Wall Street is cluless, even though recently Business Week identified this company as the one of the hot grwoth companies in America. Please read all recent messages on this board to understand LSB story.
