金程問(wèn)答第15題為什么選c呢?怎么和講義矛盾呢?
casebook中equity部分2010-2018年真題哪些不需要做呢?
老師我想問(wèn)一下R23的課后題第八題,為何股票分拆不影響投資業(yè)績(jī)的比較呢?
老師在課堂上說(shuō)到 slowdown phase in the economic cycle. Bond yield is likely inverted. 在reading 10 中 practice problem 第8題: "Based on Observation 3, Wakuluk most likely expects Country Y’s yield curve in the near term to:" A. invert. B. flatten. C. steepen. C is correct. The current yield curve for Country Y suggests that the business cycle is in the slowdown phase (curve is flat to inverted), with bond yields starting to reflect contractionary conditions (i.e., bond yields are declining). The curve will most likely steepen near term, consistent with the transition to the contractionary phase of the business cycle, and be the steepest on the cusp of the initial recovery phase. 請(qǐng)問(wèn)為什麼不能選 A? 謝謝
所以美元和黃金應(yīng)該是什么關(guān)系?
Case book下冊(cè),P6問(wèn)題D,對(duì)active risk和active share的解釋都差不多啊。其實(shí)對(duì)active share的解釋我是寫(xiě)的出來(lái)的,關(guān)鍵是對(duì)active risk的。在對(duì)active risk的解釋當(dāng)中,這句話(huà)我不太明白“Active risk,which is driven by the differences between the security weights in the portfolio and the security weight benchmark”,這逗號(hào)后面的內(nèi)容不是赤裸裸地在描述active share嗎?基本是active share的定義了啊。而且課上還講了,active share的增大未必能導(dǎo)致active risk的增大。
Case book下冊(cè),P21問(wèn)題C,答案中的第一點(diǎn)提到了看low P/B ratio,那這個(gè)不應(yīng)該算是relative value嗎(這題題干里沒(méi)寫(xiě))?怎么能算是contrarian investing呢?
第2題,Mc建議用的是passive factor based model,factor里考慮的不就是risk的exposure,所以為什么不是risk based 而是return based。
老師您好,第一句話(huà)不太理解,factor exposure is fully neutralized是不是表示active risk 公式中前一項(xiàng)為零,可是active risk 公式中還有 variance attributedtp to idiosyncratic risk,這項(xiàng)與active share 什么關(guān)系?可以麻煩詳述一下active share與 active risk關(guān)系嗎?謝謝
Case book下冊(cè)P19問(wèn)題A,課上和藍(lán)神筆記中都只提到了對(duì)于holding based approach,可以使用morning-star的圖來(lái)進(jìn)行分析,而并沒(méi)有提及使用return based approach使用什么分類(lèi)方法來(lái)分析。那么是否能將這道題中的答案,按照return based strategy的一條特點(diǎn)記下來(lái)?還是這部分已經(jīng)刪去了?
書(shū)后習(xí)題冊(cè)P140第8題,是說(shuō)只要是使用quantitative strategy的話(huà)就一定是rebalancing at regular interval嗎?而不是像使用fundamental strategy那樣可以按corridor調(diào)整?這個(gè)點(diǎn)好像沒(méi)涉及到過(guò)
老師你好,reading 25,關(guān)于absolute risk這里,我們要求第i個(gè)資產(chǎn)對(duì)portfolio variance的貢獻(xiàn),等式右側(cè)的求和公式是針對(duì)所有的i求和,我怎么覺(jué)得這個(gè)公式寫(xiě)錯(cuò)了呢,應(yīng)該是針對(duì)所有的j進(jìn)行求和,這樣求的是i資產(chǎn)和其它所有資產(chǎn)的權(quán)重×covariance再求和。
請(qǐng)問(wèn)老師,原版書(shū)R23中,在對(duì)比f(wàn)actor-based與市值加權(quán)時(shí),提到factor-based leaving investors exposed during periods when a chosen risk factor is out of favor. 這里應(yīng)該如何理解
請(qǐng)問(wèn)原版書(shū)課后題R24第五題答案解釋部分,higher p/b會(huì)有higher standard deviation這個(gè)結(jié)論是怎么得出?謝謝
書(shū)后習(xí)題冊(cè)P147第15題,根據(jù)題干中的描述security-specific factors、no factor timing、diversified,這不應(yīng)該是偏bottom-up的discretionary apporch嗎?
