My comment was that if it's true that Mnta is trading at these levels because of the fear of competition from Teva, that Momenta was overpriced prior to its original approval.
How was MNTA overpriced prior to its original approval? It was trading around $11.90 prior to approval versus today's $14.60. If you assume today's price has fully priced in TEVA approval then it clearly wasn't overpriced.
Personally, I think all this talk is pointless. Either stay long and ride out the current price action or sell your shares and move on. I think everyone would be better served spending their time and energy on other endeavors vs. speculating on short term price action.
