I think it'll take one or two quarters of respectable sales/profits and then possibly Momenta can attract a couple of decent analysts who can clean up the streets current impressions.
There are plenty of PUTS in September that buttress your thinking on this.
Or maybe someone is selling those puts to collect premiums. There have to be both buyers and sellers. Of course the market-makers can be on one side or the other.
From one who has been selling puts (and calls) on MNTA for years.
