The downward pressure has all been from a retail investor IMHO. Has anyone noticed that E-Trade has been the one who has been the biggest seller over the past few weeks and mix in a little bit of typical Cannacord who I never liked to see invest in any company that  I do, but that is another story. This must be the shares that someone has been setting at the asks occassionally when it was put in at the ask and then it would get pulled, only to show up here and there time after time and I guess that they finally pulled the trigger on it!
