You got elephant balls to be shorting nflx while it's making all time highs. I got wiped out years ago shorting Rim aka bbry in the same fashion, which by the way, is almost bankrupt now.I think I lost 500K that is why I'm such a chicken to short now. Timing is everything when you short those high flyers and it seems you may have picked a bad time to short. You are fundamentally right about the ridiculous pe, market cap, etc. etc. but the trend is not your friend right now.
