Unless Cormark was soaking up most of the shares sold recently under 0.30, they would have no profit incentive to sell them all back at 0.30 (If they were simply trying to make a profit on the open market)

I don't think (please correct me if I am wrong) that they can just "naked short" this stock. I base that on its relative illiquidity and its low price.

Any smart investor, even if unloading a holding for a profit, would likely notice the demand and start raising the ask price - even if it was done slowly. After all, why leave "money on the table" for others to take?

Given that daily volume is already significantly above average daily volume, and that there seems to be some identification of an entity who is not normally a broker for other parties transactions in the stock market, this does seem pretty fishy.
