manager1管理portfolio, 有數(shù)據(jù)如下:active risk %, absolute risk %, risk contributed to market %, risk contributed to sector %, risk contribute to 某risk %, unexpected risk %. 然后PM要做tactical reallocation, 調(diào)減utility sector 調(diào)增technology sector, 原來portfolio 和utility sector的covariance是0.04,和technology sector 的covariance是0.02。active risk和absolute risk的如何變化。求解題思路
這個題講的pearson和spearman rank在哪里有講過么?好像沒什么映象,是代表什么的呢?
此處的公式r(g)=r(a)-0.5σ^2,個人感覺類似于以前學(xué)過的風(fēng)險調(diào)整后效用公式 u=E(r)-0.5μσ^2。雖然這兩個公式的主旨不一致(此處是強調(diào)風(fēng)險會導(dǎo)致幾何復(fù)利回報率相較于算術(shù)單利回報率更低,效用公式是強調(diào)風(fēng)險會導(dǎo)致避險心態(tài)較強的投資者的投資效用出現(xiàn)大幅度的下降),但兩個公式還是有共通之處的,那就是強調(diào)風(fēng)險的負面作用。可以這么理解吧?
課后題第三題,value trap的是哪個?這個沒有做題思路
請問機考, 要寫公式alpha beta 等這些符號或者字母下標,電腦上怎么打
C股票為什么不能是Contrarian investing ?
這里說smart beta 經(jīng)常使用多個benchmark,為什么?既然是passive跟蹤指數(shù),應(yīng)該是只有一個目標指數(shù)啊
老師,題21,size 系數(shù)-0.6,老師說乘以個負數(shù)就為earnings surprise,乘以負數(shù)就是說小盤股outperform 大盤股。 我記得上課時說如果她的系數(shù)是負數(shù)-0.6,表示偏向大盤股,那偏向大盤股,又要產(chǎn)生earnings surprise,不是表示所偏向的大盤股要表現(xiàn)更好于小盤股才能產(chǎn)生收益驚喜嗎? 不知道我哪里理解對有誤,幫忙看下,謝謝。
那是否可以說,分層抽樣的tracking error比full replication要低?
我想確認一下,自上而下和自下而上的方法都屬于fundamental approach嗎?那factor based屬于quantitative approach,但是和自上而下和自下而上無關(guān)了是嗎? 謝謝
請問在 CFA practice question 中 ,Disadvantages of using ETFs include the need to buy at the offer and sell at the bid price, paying commissions, and possibly facing illiquid markets at either purchase or sale. 所有股票不是都是都buy at ask and sell at bid嗎? 還有ETFs 相較於一般股票更 liquid,為什麼這兩點是advantages?
您好,請問既然指定了地域行業(yè),為什么要選擇size/style分類?謝謝 Equity Investment Universe A portfolio manager is initiating a new fund that seeks to invest in the Chinese robotics industry, which is experiencing rapidly accelerating earnings,the portfolio manager wants to select an approach to segment the equity universe. Recommend which segmentation approach would be most appropriate Solution: Based on his desired strategy to invest in companies with rapidly accelerating (growing) earnings, the portfolio manager would most likely segment his equity universe by size/style.
請問原版書課后題第7題計算預(yù)期收益率時的cap rate為什么用的是current cap rate(5.7%),而不是expected cap rate(5.5%)?
請問reading 11原版書課后題4B中考到了基于icapm計算出的expected return,是否可以作為從估值角度判斷最佳資產(chǎn)的依據(jù)。答案是還不夠,因為expected return只考慮了系統(tǒng)性風(fēng)險。請問equity這一類資產(chǎn)的預(yù)期收益估計是不是考試僅限于考慮系統(tǒng)性風(fēng)險?
老師,請問sector rotator是指什么?最后一段是什么意思?flexibility為什么會產(chǎn)生active risk和return?
