if NFLX passes the $80 support (I do not see any problem for it) then the next possible stuck would be around $63-67 and after that around $49-53. Those are the levels were the biggest volume was accumulated. Big number of the Bulls opened their long positions at these levels and as the NFLX will be on the edge to turn a lot of bullish investments from positive into negative this will a sensitive moment for many investors. In addition these levels match past support/resistance levels.
