do not tell me you看空 and go long

比如说,你有个model,准确率是72% (就是我的SPY ST Model啦,趁机BSO一下),你看空,但是Model说是long,你怎么办?你trading的时候,要是能够没有感情色彩,那就棒了。预测是空,但是实际情况却是多的setup,这时候能够豪不犹豫的做多,那就很厉害了。预测看空,但是实际情况是多的setup,这时候如果能不入场做空,旁边等待,也是很不错的,这是只作自己感觉舒服的方向。所以,不是绝对的。预测和trading是两码事情。预测错的时候其实很多,因此看空go long,经常反而是profitable的trading,因为往往自己就是最大的反指,不是吗?很多人相信都有这种感觉,买了就跌,卖了就涨,还有,最著名的是老青蛙说的,我总是错的。
If your view is against the market, I do not see you have much chance to profit from the market at all, especially for small retail investors.

Is it possible they lie? They might hide their real feelings.
That is why I trust more on Mark Hulbert, because he is chasing the investment new letters. People do not lie to their clients they are making money from.
