What astonishes me is that he doesn't stop, but continues as the stock creeps up, taking on more exposure, when the stock very well could take off being a very speculative play, with company's management giving bullish guidance.
I saw that too. From talking to him on twitter it seems like he is banking on the waiver expiring the 31st. He already made a lot of money shorting this around Q3 2014, hopefully this time it goes the other way.
