Not this long. Obviously nflx is not trending up based on your father's stock indicator(p/e). This is a story stock with strong revenue growth and a disruptive tech..streaming video(television/computer). Netflix also has first mover status.
Could well dip to take out stops if they are big enough but surely up from these levels.
I don't think NFLX is a bad company at all. I just think for what they offer (and everyone ready to compete if not already competing) the stock is a bit over priced. What is a good price? I don't really know but if they don't improve content fast it won't be up here. I gave them 3 months to keep me as a subscriber and they didn't.
