Netflix (NFLX -3.92%) is getting bigger. After sinking to a market cap of less than $5 billion a year ago, the company's stock has surged to cross the $13 billion mark this week. That's still far from Netflix's record, which was north of $15 billion two years back:

In the following video, Fool contributor Demitrios Kalogeropoulos and analyst Blake Bos discuss Netflix's wild valuation swings. Demitrios argues that expanding profits in its U.S. business shows the strength of the company's model, while Blake takes a more bearish perspective.

The two also name a few content owners, such as DreamWorks and Lions Gate, that profit from Netflix's growth regardless of its valuation.
