Netflix operates a subscription-based DVD rental and streaming business that provided steady revenue growth. From 2008 to 2011, Netflix's revenue grew 46% annually through increasing subscriber numbers. This rapid revenue growth led to strong earnings growth and a 2600% increase in its stock price. Netflix was able to leverage its fixed costs as revenue increased, nearly tripling its operating profit over this period. The company exhibited strength prior to the market bottoming in early 2009, putting in a second low in November 2008, while its relative strength line was rising, signaling it as a potential leader.
