"Many have already given up, that's for sure. Short interest was 16-23 million shares going into QE2 at half what AMZN sells for today, now it's down to just 8.7 million shares." --SeekingAlpha
Even on this board it seems nearly all the perma-bears who have harassed other posters here for several years or more have suddenly vanished recently, their positions utterly crushed. Only the naive newbies remain. Shorting a stock because you insist it is "overvalued" can be a suicide mission for the stubborn valuation obsessed short-seller.
You sell when you need the cash. If you don't need it, why sell too early and miss the upside?
I know a poster who thought $130 was a good time to sell. He did but the stock pulled back for so short a time he was never able to repurchase shares at that level and missed the run from $130 to $260. Some of the brain challenged shorts try to say that was a great move, and what's really funny is that some of the dumb longs here believe that.
"Many Long-time Shorts Have Thrown In The Towel"
You're wrong, nemesis.
Most shorts here got their positions liquidated by their brokers. They always hang onto their losing short positions until their brokers pull the plug.
As the article I quoted mentioned, over 60% or 70% of the shorts are gone now. That is simply a fact. Also, nearly all of the long-time short trolls who used to be obsessed with posting dozens of times daily have stopped posting. I would say about 95-99% of them are now gone.
Whether or not they are forced out by brokers or by setting foolish stops ("oh, no way could it go over $230, because then the PE would be blah, blah, blah...") doesn't change this observation.
