I don't have time to go into all the detail - you should read some of our old posts and find out why...but it has to do with Short Sellers have to cover their shorts, which means they have to purchase stock. In PK, MM's tend to short stock like crazy even to the point of shorting more shares of stock than they have made arrangements to purchase in the future, which requires them to go into the open market and purchase @ whatever price the market will bear. In addition, if multiple MM's have done a lot of "naked" short selling (which is what I just described is called) then there is a huge demand and it really drives the price up. A lot of MM's don't want to have to do that, because they will loose a lot of money, which is why many think this name change is taking so long - it is enabling MM's to try to cover their short positions...but there should still be enough momentum to really drive the price up.
