这是一本介绍99个人性心里误判的书。

决定一位投资者能够长期在股市生存並蓬勃发展，除了在股项上的选择，在时间点上的选择也间接决定了不同程度的赚幅。

理性的思考每一位投资者都晓得，然而在思考上的误区却不是每一位投资者都能探知的。打个比如，当一只股票的价钱，从投资者的买进点下跌了10%，市场上的投资者就会出现以价钱来决定导向的两派人马，一派会选择加码，另外一派就会选择割肉离场。这时市场就会反映这两股力量的较力。割肉的越多当然会加剧股价下跌的趋势，因为股价的再一次下行，这会引致更多的割肉，甚至是践踏的现象。不管在之前做了什么功课，都会被股价给冲击而丢掉九霄云外。

作者在第50个误判就指出了他自身在股市上经历的：- 用了伊索预言里头，吃不到葡萄说葡萄酸的狐狸故事。

“.. when i had to choose between investing in two different stocks. My chosen stock lostmuch of its value shortly after the purchase,whereas share in the other stock, the one i hadn’t invested in, skyrocketed.  I couldn’t bring myself to admit my error. Quite the reverse, in fact: i distinctly remember trying to convince a friend that, though the stock was experiencing teething problems, it still had more potential overall. Only cognitive dissonance can explain this remarkably irrational reaction. The “potential” would indeed have been even greater if i has postponed the decision to purchase the shares until today. He friend said to you, “You can play the clever fox all you want - but you’ll never get the grapes that way”.
