David Gardner first recommended Netflix (NASDAQ:NFLX) in May 2003, nearly 10 years ago. Since then, he's gone on to rerecommend it three more times for subscribers of his Stock Advisor service, and each of those positions has at least doubled.

After a steady ascent, Netflix's share price has been on a bit of a rollercoaster ride over the past 18 months, dropping from about $300 per share all the way down near $50. It's since doubled from those lows.

Having stuck through the good times and bad, David now rates it as a "best buy." During a wide-ranging interview last week, I asked David what would make him consider selling Netflix at some point in the future. You can watch his answer in the video below (run time: 1:11), but it all boils down to management -- specifically, Reed Hastings.
