My comment was based on the fact that it is hard to imagine anything dramatically moving this stock in the next two weeks other than an announcement regarding the TEVA ANDA. Given that the put volume was at the ask rather than the bid, it seems logical to assume that the impetus for the trade was someone who wanted to make a bet on the short side.
Obviously, there could be any number of reasons for the large put volume. I believe my speculation is the most likely.
