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
