Wow SP has almost doubled in 5 days !! Once again it has dawned on me that SP is simply a reflection of the sentiment of the investors,traders, etc. Not much has changed in the last 5 days in terms of fundamentals of the Co. Someone pointed out to me the other day that the product to be launched is merely a piece of plastic. So I can't help wondering how the SP moved so far so soon! May be it is time to take profit.
