同學(xué)你好
Returns-based style analysis (RBSA)有兩個優(yōu)點:
1)Although RBSA adds the additional analytical step of estimating the risk factors, the analysis is straightforward and typically does not require a large amount of additional, or difficult to acquire, data. 雖然RBSA增加了額外的分析步驟來估計風(fēng)險因素,但是分析是直觀的,通常不需要大量的額外數(shù)據(jù),或者很難獲得數(shù)據(jù)。
2)It can be estimated even for complicated strategies and is comparable across managers and through time. 即使對于復(fù)雜的投資策略,它也可以被估計出來,并且可以在不同的基金經(jīng)理和不同的時期之間進(jìn)行比較。
而他的缺點有以下兩個:
1)The disadvantage is that RBSA is an imprecise tool, attributing performance to a static portfolio during the period that might not reflect the current or future portfolio exposures. 缺點是,RBSA是一個不精確的工具,它將業(yè)績歸因于一個靜態(tài)的投資組合,而這個靜態(tài)的投資組合可能無法反映投資組合當(dāng)前或未來的風(fēng)險。

2)The portfolio being analyzed might not reflect the current or future portfolio exposures. 所分析的投資組合可能不能反映投資組合當(dāng)前或未來的風(fēng)險。
If the portfolio contains illiquid securities, stale prices may understate the risk exposure of the strategy. 如果投資組合中包含流動性差的證券,過時的價格可能低估了該策略的風(fēng)險敞口。
is comparable across managers.
is suitable for portfolios that contain illiquid securities.
can effectively profile a manager’s risk exposures using a short return series.
A選項說,在不同的管理者中具有可比性。這個是對的,這是他的第二個優(yōu)點
B選項說,適用于包含非流動證券的投資組合。這是錯的,因為這是他的第二個缺點
C選項說,能夠有效地利用短期收益來分析經(jīng)理的風(fēng)險敞口。這是錯的,因為RBSA是不能反映當(dāng)前和未來的風(fēng)險的,所以不能用來分析基金經(jīng)理的風(fēng)險敞口 -

同學(xué)你好
Returns-based style analysis is a top-down approach that involves estimating the risk exposures from an actual return series for a given period. 基于收益的風(fēng)格分析是一種自上而下的方法,它涉及到從給定時期的實際收益率序列中估計風(fēng)險。
Holdings-based style analysis is a bottom-up approach that estimates the risk exposures from the actual securities held in the portfolio at a point in time. 基于持倉的風(fēng)格分析是一種自下而上的方法,它對組合中某一時點實際持有的證券的風(fēng)險敞口進(jìn)行估計。
這題問哪個是bottom-up approach,所以是Holdings-based style analysis ,因此是選B。
