这题用排除法。Jordan是overconfidence bias，题干用了大量的文字描述，AC表现的很明显。B, representativeness bias用以前的套路分析新的信息，这题没有分析新的信息，本质上还是因为Jordan太自信认定这个策略以后也是有效的。

补充一下：原版书123页提到这个是naive extrapolation of past returns

不是很明白，小助手提这个naive extrapolation of past returns 是什么意思

NO.PZ201511190100000306 一方面，通过representativeness bias与conservatism bias的辨析来学习，可以理解较透彻，Base-rate negleansample-size neglect也能理解地很好。对于此题而言，如果representativeness bias是对新信息overreact，那么文中主人公对价格反转的坚信，就算表现了什么，也应该是conservatism bias。 另一方面，教材对representativeness bias的定义又看得很难受，people tento classify new information baseon past experiences anclassifications，一下子搞得文中主人公的行为似乎也符合这种定义。 所以，真的是对representiveness bias很晕
