JB said he sold most of his shares between 3.30 and 3.40. That move has now been shown to be totally wrong. What JB should have done if he wanted to diversify was say he was selling for that reason and NOT because Xin was a bad stock.
Real deal is "No Body Knows For Sure" and if you think you do you'll lose. All you can do is buy and hope its a good investment all the rest crystal ball crap
Humility doesn't seem to be something that comes naturally to JB!!
