为什么HBSA和RBSA都不适用于illiquidity 的时候

NO.PZ2019093001000009

问题如下:

Compared with holdings-based style analysis (HBSA), a returns-based style analysis (RBSA):

选项:

A.

is subject to window dressing.

B.

requires less effort to acquire data.

C.

is more accurate when illiquid securities are present.

解释:

B is correct.

RBSA typically does not require a large amount of additional, or difficult to acquire, data. HBSA requires data on each security in the investment portfolio. HBSA is a snapshot of the portfolio at a single point of time and thus is subject to window dressing. Both HBSA and RBSA are subject to difficulties in interpreting returns when illiquid securities are present.

嗨,从没放弃的小努力你好:


HBSA和RBSA面对流动性不好的产品,解释收益时都比较困难。流动性不好的产品,它们的价格变化一般都会产生时滞,这样评估出来就不准确。所以这是两种风格分析的通病,不适合流动性较差的产品。
