Interesting question !
Maybe the brokerage has to hold "extra" shares to cover this eventuality ?
Or buy more of them (even though they are falling ?)
Maybe that why banks with brokerages take such a hit when things go south...
I am a bit surprised to see that 30% of this stock was (apparently) shorted months ago...
I never saw it on RoB's (anemic) list of large short positions...

.
But then since they are too lazy to use "% of float" as a criteria, I guess a company with only 60 Million shares (20 million shorted) flies under the radar...companies like ENB,BNS with ? 800 Million shares would be listed (42 Million shorted)....
More great in depth coverage....
.
How was it still trading at $35 if 30% was shorted is pretty amazing...
Many mysteries.
