Yeah--hurts a bit if you're a day trader. You don't buy a thinly traded stock for a pop unless you have a lot to spend. If you understand the biotech world and the risk that goes with it, then you need a bit of patience to get the reward. Nothing is free, and you have to take larger risks to get out-sized rewards.
I am not a day trader, and MACK is not a $50 stock. Therefore, please discontinue your pumping up of this stock. The bottom line is, MACK is burning cash very quickly and does not have any products that have reached the marketplace. Most likely, they will be required to raise additional cash by offering more share and further diluting the pps.
