Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of online content streaming and DVD rental company Netflix (NFLX -2.52%) jumped as much as 15% after announcing a content deal with the House of Mouse, Disney (DIS -0.93%).

So what: The movie-licensing deal Netflix and Disney signed today will give Netflix the exclusive rights to all Disney studio, Pixar Animation Studio, and Marvel Studio productions beginning in 2016, and brings a catalog of Disney classics to U.S.-based Netflix subscribers. Netflix can also begin delivering direct-to-video Disney releases beginning in 2013.

Now what: Today's deal is a much-needed boost for Netflix's streaming business, since its DVD business has been losing customers on a steady basis for many quarters now. Peer Amazon.com (AMZN -1.35%) has been ramping up its online digital library and boasts a considerably larger cash balance, which makes negotiating content deals much easier. For Netflix, it'll need to negotiate more deals similar to this before I'd declare its growth trend back on track. For now, however, I consider today's pop the perfect opportunity for those who find themselves up on their investment to consider heading for the exits.

Will the Disney deal be just the beginning of a Netflix turnaround, or is this a temporary pop in a stock with little long-term business viability?
