POET Technologies Inc.

I was hoping (obviously) the share price would start to move up this week. I just looked at Stock Watch and Canacord is selling and most are 500 lots. I don't understand why the stock has not even made it up to 36 cents the price of the offering since the PO was priced. Who would be trying to keep the price below 36 cents and why? Anyone have any idea? I would have thought the shorts would have had time to cover by now.
