问题如下图：
选项：
A. 
B. 
C. 
解释：
为什么不是C呢，题中还提到include a plan,说明是有计划而非随机性的啊，根据定义：Discretionary TAA is predicated on the existence of manager skill in predicting and timing short-term market moves away from the expected outcome for each asset class that is embedded in the SAA policy portfolio.
Using signals, systematic TAA attempts to capture asset class level return anomalies that have been shown to have some predictability and persistence，感觉应该是C啊

NO.PZ201805280100000207 答案中给出的rule-base然是通过经验法则得出的，难道不是人凭主观经验得出的法则么？是否和systematic TAA中的quantative相矛盾呢？
NO.PZ201805280100000207 systematic tacticasset allocation和scretionary tacticasset allocation的定义是什么，并举例说明！
我是不同意答案的 文中没有任何迹象表明低于200天的MA就要增加5%的头寸是根据量化数据得来的 更多的是一种经验法则
