ALXN down from it's high?

I have to say I envy those who didn't lose faith when ALXN fell from $28 down to $20, because just a few days ago it was trading at around $38, a very nice 1.5x for anyone who saw the recovery from $20 and jumped on board.
Sadly, I'm not one of those people, and I'm here to celebrate the fact that the party's over - ALXN's down to $35.25 after hours. I'm short - are you?
