The ‘Slope of Hope’, the Wall of Worry’, call it what you like, but the market snow drifts higher. The CEO of NFLX is channeling his best Patrick Byrne from Overstock.com as he defends the outlandishness of someone actually shorting his stock. Such heresy. How could anyone short one of the most extreme momo names of 2010 with thinning margins going forward? After all, it was just invited into the S&P 500. I don’t have a horse in the race, an ax to grind or a hat in the ring on this one, but it should be a very interesting first quarter for the name.
