Netflix (NASDAQ:NFLX) has started the year in impressive fashion. So far this year, Netflix stock has run nearly 150%. While the company has served as a model for Amazon (NASDAQ:AMZN) Prime and Redbox Instant -- the joint venture between Coinstar and Verizon -- understanding the difference between Netflix stock and Netflix itself is important.

If the company cannot grow revenue, eventually Netflix stock will be punished as well.
