If we want to make any reason out of this .. some

If we want to make any reason out of this .. some body is sitting on pile of shares and using this opportunity and volume generated by the news to get rid of their shares.. as you said there are only 2.5 k shares available at the highest bid .. but for him to sell 100k he has to go lower ...
I am waiting when will they get exhausted with their shares! Hope it is today!!
