I don't agree with most of SA's points, he has every right to post his opinions. He seems like a fine person to me. Calling people maggots and the like is really counter productive. I have made a lot of money on ARMH despite his posts.
I feel he is more knowledgeable then me on all of the technology of the chip makers. I feel I am more knowledgeable then him on how stocks move and trade and general business operations.
I have seen many stocks I wanted to short, and most went down, but I believe shorting involves too timing much risk.
