No you can be negative if you are ready to sell at $20 perhaps $50. As long as you invest in biostocks to become billionaire not just x1 or x2 you are fine !
Nothing wrong with stating a current opinion, however, when all opinions are negative then it is fair to be challenged by others who doubt your agenda. I have always been positive and negative at times. Suspect when views are all positive or all negative about pphm.
