Slicken,
Ever heard the saying, "buy the rumor, sell the news"? King has indicated that trial updates will happen in late 2008 or early 2009. Anticipation is building. IMO, that MM's and astute traders are starting to buy in anticipation of the "news" or release of data. They are expecting that the news will be good and that the publicity will attract buyers, new and old. If it goes as planned, the buyers will show up and the guys that are buying now will be there to sell them their shares. If the news is good and they don't have enough shares to stop the rise, we're off to the races. If the news is just ok, the selling from these "front runners" will slow the rise, eventually stop it, and void new news, we'll head down again. Neat thing here is that we're expecting many news events. So, the old buy the rumor and sell or short into the news is getting riskier.
Regards,
WH
