当有 illiquid asset的时候，return base和 holding base 是不是都表现出劣势？

问题如下：

An advantage of a returns-based style analysis is that such analysis:

选项：

A.

is comparable across managers.

B.

is suitable for portfolios that contain illiquid securities.

C.

can effectively profile a manager’s risk exposures using a short return series.

解释：

A is correct.

Returns-based style analysis on portfolios of liquid assets is generally able to identify the important drivers of return and the relevant risk factors for the period analyzed, even for complicated strategies. In addition, the process is comparable across managers and through time. If the portfolio contains illiquid securities, the lack of current prices on those positions may lead to an underestimation of the portfolio’s volatility in a returns-based style analysis. Longer return series generally provide a more accurate estimate of the manager’s underlying standard deviation of return.

嗨，从没放弃的小努力你好：


是的，两种style analysis均不适合含有 illiquid securities的组合。
