金程問(wèn)答reading18原版書(shū)例題example10第一問(wèn)
這里說(shuō)active share越大 active risk就越大。那有沒(méi)有可能我確實(shí)沒(méi)有去replicate benchmark的持倉(cāng) 我就是選了不一樣的股 只是這個(gè)股的特征和benchmark的個(gè)股差不多。 這個(gè)就好像債券在做replication的時(shí)候 并不一定要買(mǎi)一模一樣的債券 而是保證那幾個(gè)primary risk一致就行了
L3V3. Compared to Equation 2 and Equation 6, does that indicate alpha in Equation 2 is a constant?
(1) Will there be any security that is not in the benchmark but get included in the portfolio? (2) If yes, what is this return called? (3) Why active return does not include such a return?
老師講解的neutralized factor exposure指組合跟benchmark配置一樣,factor risk=0。既然配置一樣,為什么還會(huì)產(chǎn)生選股不同,存在active share呢?不是太理解。
104頁(yè)例題,老師講A基金經(jīng)理大部分超額收益來(lái)源于market,market不只是一個(gè)benchmark的收益嗎,怎么會(huì)提供超額收益呢
B和C 是什么意思?
excessive,trading,bias能說(shuō)明一下嗎?
R18原版書(shū)課后題11題,選項(xiàng)B為什么不對(duì),題目說(shuō)portfolio has high active share ,選項(xiàng)C multi factor manager 滿(mǎn)足這個(gè)條件嗎,麻煩解釋一下選項(xiàng)B和C
老師,請(qǐng)問(wèn)為什么Short positions might reduce the market return premium ?
Q36: 這個(gè)和老師在課上說(shuō)的方法不一樣,算出來(lái)也不一樣。講義125頁(yè)
Fundamental weighting’s intended advantage is overweighting stocks priced below intrinsic value and underweighting overpriced stocks.這句話(huà)怎么理解?
第一個(gè)限制條件計(jì)算出來(lái)的是組合中單只股票的最大市值是3billion嗎?那第三個(gè)限制條件計(jì)算出來(lái)的又是什么呢?好像也是單只股票的市值。
老師,麻煩講解下這個(gè)case的這個(gè)問(wèn)題,謝謝
麻煩兩下這道題
