My attitude is not to give them benefit of doubt in this type of situation (apply to all of my pharma/biotech investment). They have to prove their case to me. Teva hasn't done that.
I believe sentiment in general is shifting now on MNTA's stock price and this shift will be further cemented with the earnings release on Monday.
It seems to be moving from: tLovenox is coming, MNTA's share price is suppressed until proven otherwise (FDA rejection which might not be divulged) -to- tLovenox is not coming, MNTA's share price runs until proven otherwise (FDA approval or information indicating progress towards tLovenox approval)
