Typically when someone wants shares they contact the market maker .... ie the guy who already has a bunch. That is why we see all of our favourite brokerage houses selling and buying at the same time.

They probably sold the shares to their client for 72 cents. Guaranteed a price based on current market and then traded the market to buy them at a better price. that's what market makers do. At least in the US the MMs have to declare themselves as such and must always be on both sides of the trading spectrum. If they are shorting they must have a bid on and vise versa. At least then you can see a potential trading range.
