I too sold 25% of my position last week.  I'm not normally prone to moving off a position like that, but the combination of a news release that seemed to underwhelm the market (not me though, it seemed like pretty good news...go figure), and the market in general melting down, it just seemed wise to get some off the table and into cash.  

That being said, I fully intend to by back that 25% next week if the market seems to be returning to some semblance of normal.  I have nothing but confidence that Kodiak will be a huge success in the coming months and years, but if I can get some of my gains out of play and then buy back what I sold(at a much cheaper price)...why not?
