Other than, perhaps, your portfolio 'whats' a bump, what can you possibly see that would make you think this stock is "oversold?" It's trading at a ridiculous valuation (no stock has EVER been worth this sort of multiple), earnings growth is suspect, and the market seems to be trying to roll over on top of it.
Crazier things have happened but, bump or not, this is a falling knife. Gravity sucks - don't stand under falling things heavier than you.
It's hard to gauge NFLX because when it fires up, it goes up days in a row for now reason or rhyme and same when it goes down. This stock is traded on news driven pumps and dumps. So it's very easy for it to reverse from here at close at $175 tomorrow.
