问题如下：
Chen’s preferred portfolio management approach would be best described as:
选项：
A.top down.
B.systematic.
C.discretionary.
解释：
C is correct. Chen prefers an approach that emphasizes security-specific factors, engages in factor timing, and typically leads to portfolios that are generally more concentrated than those built using a systematic approach
虽然选对了，这道题为什么不选A

嗨，爱思考的PZer你好：
虽然选对了，这道题为什么不选A
Hello，亲爱的同学！
我们看这段描述
Chen prefers an approach that emphasizes security-specific factors, engages in factor timing, and typically leads to portfolios that are generally more concentrated than those built using a systematic approach
chen同学喜欢的方法是，强调emphasizes security-specific factors。
结合我们基础讲义的表格：
emphasizes security-specific factors的是bottom up。
如果是A，top down，它的特征是：emphasizes macro factors。因此不选A。
----------------------------------------------加油吧，让我们一起遇见更好的自己！
