问题如下:
Which of the following regarding technical analysis is most appropriate?
选项:
A.
The opportunities in technical analysis are not market anomalies but risk exposures.
B.
Technical analysis is still available if market can incorporate all information into prices accurately and instantly.
C.
Emotions of investors can affect market prices, therefore technical analysts can focus on the buy and sell signals.
解释:
C is correct.
考点:行为金融对市场的影响
解析:Momentum, 是投资者情绪的一种表现,因为人们在短期容易低估一些信息的重要性,在长期高估一些信息的重要性,预期不同做出的决策也不同,这就会影响到市场价格,所以采用技术分析的人关注价量变化、买卖信号 。
常见错误选A,注意Momentum是 market anomaly 也是 risk exposure。
为什么呢?课件中说有几种并不是market anomaly的情况,第一种就是model选择错误,把没有发现的risk factor当成market anomaly. 那momentum作为一种很常见的risk factor,为什么是market anomaly呢?
