题目：

A technical analyst makes the following claim:"The stock of MBR Co. will soon enter a downward trend from its current equillibrium price as a result of unfounded fears of local terrorism and an overabundanceof sellers in the market.Expect to hold a short position for a long time as the trend(like most trends)willbe persistent."Which of the following assumptions made by the analyst is inconsistent with technical analysis?

A interaction of supply and demand causes trends in stock prices

B Trends are stable for long periods

C The market moves in trends

D Supply and demand is governed by both rational and irational factors

答案是B

trends can change as supply and demand change

可是NOTES P241 上LOS3 B a说security prices move in trends that persist for long periods of time

这话是不是矛盾，还是我理解有问题？或者我的鸟语真的很差？

请大家指教！！

I think you should focus on the periods, especially " s "

Technical analyst assume the trend is existing, but they cannot specify the trend's real time style.

不好意思，我不能理解你的意思，能否解释一下？

我的意思是：技术分析承认有趋势存在，但分析师并不能确认趋势的周期。

Ｎｏｔｅｓ上用的是复数，想说明的是长期来看趋势确实存在，但并没有说趋势本身（我的理解是趋势线）的稳定性。

不知道解决明白没有。希望大家多讨论！！！

谢谢
