问一道题:NO.PZ2019103001000088 [ CFA III ]

问题如下:

Wang made the following statements about the advantages and disadvantages of the top-down and bottom-up approach

Statement 1: One advantage of the bottom-up approach is that it is easier to gain an informational advantage in individual companies or bonds rather than the overall market.

Statement 2: Another advantage of the bottom-up approach is that it can be easy to earn substantial returns from bottom-up security selection without exposing the portfolio to macro factors.

Statement 3: One advantage of the top-down approach is that sizable portion of credit returns can be attributed to macro factors.

选项:

A.

Statement 1 and statement 3 are correct.

B.

Statement 1 and statement 2 are correct.

C.

Statement 2 and statement 3 are correct

解释:

答案:A is correct.

考点:Top-down, bottom-up方法的优缺点对比

解析:Statement 1和Statement 3正确,为原版书原句。

Statement 2错误,正确的应该为:即便用Bottom-up的方法选择出了合适的个股,Credit returns中很大一部分仍可以归因于Marco factors,Statement 2中,easy to earn a substantial return without exposure to macro factors错误;

原版书原句为:

Because a sizable portion of credit returns can be attributed to macro factors, it can be difficult to earn substantial returns from bottom-up security selection without exposing the portfolio to macro factors.

第一条为什么正确?宏观信息一般不是更好收集吗?个体企业信息很多可能不会披露吧

不是的哟。

就比如说 各国政府债/GDP比率吧,很好获取,但是你获取的信息是滞后的,他不是每天,或者每个月都更新的,有很过宏观数据至少要等上一个季度,半年甚至一年之后才会发布。

但单个公司不一样,一个公司研发出一个产品,在宣布的时候就能马上收集到信息了,你还可以调查这个公司进的存货来猜测这个公司的产能是不是要增大。
