金程問(wèn)答free-float weighted indicies operate based on the validity of the efficient market hypothesis,whereas fundamental weighting operates to exploit possible inefficiencies in market pricing 怎么理解?
第1題為什么不是選的optimization 因子之間不相關(guān)不就是線性回歸的假設(shè)么
2016年B問(wèn)老師講得好亂,聽不懂,能再解釋一下嗎?return based/holding based 是如何支持/不支持mandate
第三題,statement 2這句話我覺得不對(duì)哦。Since GESG’s benchmark has fewer constituents than the Russell 1000? Index, GESG should have a lower tracking error than it would if it were tracking that index. "fewer consituents"不代表lower tracking error吧,難道不看liquidity嗎
第四題為什么不選C。 Second, I seek contrary viewpoints from other investors and sell-side analysts, as well as set and enforce proper portfolio diversification rules. 我覺得這個(gè)已經(jīng)解決了B 選項(xiàng)的overconfidence bias.

是否可以理解為:active share 是active risk的一部分 (Idiosyncratic )
active risk分解的時(shí)候alph 去哪里了?因子偏離項(xiàng)里面的sigma是什么的sigma?
有點(diǎn)亂,factor tilling就是factor weighting?之前講factor timing是使用unrewarded factor,需要調(diào)整factor前的系數(shù),怎么分解active return這里的factor timing又變成了挑選rewarded factor?
請(qǐng)問(wèn)這句話是什么意思,具體邏輯是什么?will experience return....
為什么equal weighted index 是偏小市值呢?
直播:2022.8.28 權(quán)益寫作專項(xiàng):https://grr.h5.xeknow.com/sl/2N0Rgk,能換個(gè)專業(yè)點(diǎn)的老師重錄嗎?權(quán)益那么重要的科目,就那么隨意忽悠大家?。课翘榈穆曇舸蟮綈盒?,影響思考,本來(lái)直播就是要把不懂的弄懂,鼻涕聲又大聲又頻繁,屏幕還要頻繁地拉動(dòng),怎么集中注意力???
