第2問,表格1中給出的是不加限制條件下的系數(shù),加上限制條件不就可以得出4個風(fēng)格的占比進(jìn)而得到style box嗎?還是說style box只能是holding-based,不存在return-based的做法?
ETF shares can be bought by investors using margin borrowing; moreover, investors can take short pos
老師,factor based 方法屬于基本面還是量化?
第3題,成分股越多在不考慮交易成本時,trackingerror不是越低嗎
兩個問題,在計算active share的時候為什么要除以2?如果portfolio和benchmark沒有任何相同,那么它的active share應(yīng)該是0.5吧,怎么講義里寫的是1呢?是我自己理解錯了嗎?
在reading 25中 480頁對于active risk的原版書有四句話,請老師詳細(xì)解釋下: ■ high net exposure to a risk factor will lead to a high level of active risk, irrespec- tive of the level of idiosyncratic risk; ■ if the factor exposure is fully neutralized, the active risk will be entirely attributed to Active Share; ■ the active risk attributed to Active Share will be smaller if the number of securi- ties is large and/or average idiosyncratic risk is small; and ■ the level of active risk will rise with an increase in factor and idiosyncratic vola- tility
第一題,Arya 表面看上去target active risk很高,大家都以為是主動管理,但實際上Standard deviation of return較低,這不符合closet indexing的定義嗎?至于Maximum sector deviation和Maximum risk contribution to a single security這和closet indexing有啥關(guān)系?
Risk-oriented strategies 通常會和fundamental weighted index相關(guān)嗎

什么是concentration lvl

第7問,active share和這兩筆trades之前一樣,是1pp吧?文字解析給的是2pp
老師,這里第二題我有點疑問,原版書上寫著security和firm的factor都應(yīng)該算是bottom up的呀。為何這里fund 2不算bottom up
這道題選A:但是我的理解是,如果使用fator-based,不是可以避免risk overlapping 嗎,這也是這個模型的優(yōu)勢。那跟A的表述是沖突的,應(yīng)該怎么理解?
