I don't think anything is up. At these prices, what's the point of selling? Buying makes a bit more sense, if you invest what you can afford to loose. My guess is the total amount of money transacted in corx since the beginning of the year is well below $100K. I think this is nothing but noise.
Actually, I think there is something up: cor is outperforming other penny stocks, and this is attracting investors. On a nano scale this is a virtuous cycle: people are buying because people are buying. Underneath that, there probably is some awareness that the stock is undervalued, but I doubt that most of the people who are buying are doing it for anything other than the short-term: ride it up for a week, then switch.
Has anybody bothered to do a Freto-style pincher analysis of corx?
