RE:Upon closer analysisI agree with careful if you mean don't invest money that you can't afford to lose, as there is no doubt this one is high risk. However, I have been watching this company for two years now, hanging on news every week, whilst doing as much research as I can on the technology.
This appears to be solid tech, and management certainly appears to be doing a great job. Yes, there is a high degree of speculation priced in at this point, but that is the nature of the stock market when you have a potentially ground breaking technology nearing commercialization.
