My guess would be that he is already out. He always talks up his positions, but he hasn't said a word about NFLX in the past couple of interviews. He wasn't enthusiastic about keeping it anyways, but he didn't want to hear his son cry.
I highly doubt Icahn will have much of an effect on NFLX moving forward. He had a hot hand for a minute and people were riding his nuts. If you look at his lack of success recently I think you will see how ineffective he has been. He lost the battle on Dell, couldn't force the buyback with AAPL, no spin off of paypal, and face ripped off on HLF recently.
I agree that corporate governance is pathetic, but he couldn't care less about the long-term health of companies he gets involved with. I have owned several companies he is involved with like CHK, DELL, EBAY, and AAPL and could care less if he is in or out. When he says nonsense like Apple is a no-brainer, or DELL is way undervalued, you know he is full of it. Ignoring the fact that the PC market is dead and that smart phones have reached their pique is reckless. In markets like this, nothing is a no-brainer.
