Could be that 2011 is shaping up to be the same kind of "anomaly" (as zugibe so often comments) that 2009 supposedly was. I sold my shares a couple of weeks ago for 2.00 and bought.....GOOG HDSN is a real loser: stagnant share price, extreme P/E, no dividend, in debt...look at 8-K justy filed recently...the list goes on and on and on....get into something that moves a little not this POS that somedays trades 3,000 measely shares...OINK!!!! HDSN has only one thing going for it...a fan...Marathon Capital Management...big f-ing deal. GO GOOG!!!!
