I wonder why some folk post negative comments (no facts nothing just comments) on the stock while they don’t hold any…if folk don’t hold stock, why would they even look at that stocks threads unless it is to look for information to make an investment decision in it, but why post comments negative or positive, but specially negative comments, unless they want to post a not so commonly known fact that they have come across about the stock which could inform share holders?. I am reminded of the quote from Batman’s Joker (Jack Nicholson) “Never rub another man’s rhubarb”
