time lag的问题

  1. CFA I
  2. Portfolio

NO.PZ2018101901000027

问题如下：

Drawbacks of technical analysis include which of the following?

选项：

A.

It identifies changes in trends only after the fact.

B.

Deviations from intrinsic value can persist for long periods.

C.

It usually requires detailed knowledge of the financial instrument under analysis.

解释：

A is correct.

Trends generally must be in place for some time before they are recognizable. Thus, some time may be needed for a change in trend to be identified.

请问一下，老师所讲的time lag其实基本面分析和技术分析都是有的，基本面的time lag 是基于年报，而技术面是从历史数据推未来那也就意味着两种方法都是跟不上market的变化的。

另外，技术面是可以再某个周期内能快速把握上升和下跌的趋势的，但是基本面却不能

这样理解是否正确
