Now let me add to my last post that a novice can lose a lot of money if he uses what seems to be common sense. He might think, if they were flying when they were losing a lot of money, now that they are making a lot of money and the predictions are that they will make even more, then they are going up even more. So I am going to buy here and make a lot of money. And then he sees them going down and down. But he waits because the valuations are so low and the earning predictions are so good. Then guess what can happen? Yes that's right the companies start warning and losing money and bang! they really crash and he is now broke.
