You post that like you have information that nobody else does. You are making assumptions. Maybe the service with evolve into something more and maybe it won't. That is the question that only time will reveal.
Day traders and retail investors make investment decisions based on assumptions and feelings. The smart money doesn't and will not begin to exit NFLX until it appears they will falter.
I don't have a position in NFLX after this morning. I have mostly been short NFLX via puts but from time to time have bought calls. I will buy whichever contract I think will prove profitable this week as I don't care how I make profits. My feeling, right now, is that NFLX goes back above $200 by OP EX.
