MCLN is not just running up on "air". As some of our informed poster had pointed out... the current available float of for this stock is at or near zero. There is a buy to cover pressure which is why the price has been running up form the past weeks. The last time I check the Naked Short List for today, MCLN is still on the list. http://www.buyins.net/tools/short_list.php?ssd=20091127
People get so offended when you tell them any different. Its a stock. No stock is any different from any other stock. It will pullback and already has a good deal. Do yourself a favor and maybe listen and maybe you can make more money by buying back in at a timely place.
