金程問(wèn)答最后比較的 hedging 和integrated 方法里面說(shuō),linear or nonlinear correlation 指的是什么啊 上又說(shuō)只有surplus op: link asset and pv of lib through correlation coiefficient
老師,你好。原版書reading 5(asset allocation)example 9中關(guān)于corporate pensiion 和endowment這兩個(gè)關(guān)于主動(dòng)或者被動(dòng)投資的影響因素能否解答下?
MVO例題中,有一個(gè)includes spending rate3%,這個(gè)條件沒(méi)有用,這個(gè)條件怎么理解呢
老師好關(guān)于REBALANCE,流動(dòng)性差的資產(chǎn)這一段怎么理解啊However, rebalancing of an illiquid asset may be affected indirectly when a highly correlated liquid asset can be traded or when exposure can be adjusted by means of positions in derivatives. For example, public equity could be reduced to offset an overweight in private equity. Rebalancing by means of highly correlated liquid assets and derivatives, however, involves some imprecision and basis risk.
重音,馬賽克,沒(méi)法看
你好這個(gè)反響求解怎么求,有過(guò)程可以看下嗎?
reading7 課后題19、20 老師,(1)allocation to PE,相對(duì)于被投資資產(chǎn)的AUM,allocation占比什么情況是relatively small ,什么情況是overly concentrated?(2)10%allocation to PE,對(duì)于foundation算多嗎?foundation的特征之一不就是多投資于另類資產(chǎn)?這種情況如何判斷?謝謝!
reading7課后題16 老師,借由此題,我想到幾個(gè)知識(shí)點(diǎn),您看我的理解對(duì)嗎:(1)reading5講到,volatility越高—>more divergence from SAA—> narrower range;(2)reading7, taxable portfolio—>higher transaction cost —> wider range; (3)這道題,稅后volatility更低—>less divergence—>wider range(和(1)的解釋一致,即volatility與range反相關(guān))。老師,這幾個(gè)知識(shí)點(diǎn)有關(guān)聯(lián),我的思路對(duì)嗎?謝謝!
課程順序有沒(méi)有問(wèn)題,為什么老師一直在說(shuō)昨天上課的內(nèi)容
R7課后題18題答案里,沒(méi)看懂第一段是什么意思,第二段答案也有所矛盾,題目中都說(shuō)了是為了十年以上不可預(yù)測(cè)的花銷,那么就不需要流動(dòng)性,是retirement需要流動(dòng)性吧?這里答案沒(méi)看明白,多出來(lái)的錢為什么不能放到retirement a/c?這本來(lái)就是part of retirement payout呀
R6課后題第18題,Goal 2計(jì)算公式,在有限時(shí)間,每個(gè)CFs間有增速,時(shí)間比較長(zhǎng)沒(méi)法一個(gè)一個(gè)算,這個(gè)的公式是?還是說(shuō)計(jì)算器能直接敲出來(lái)?(忘了)
reading6 課后題15 請(qǐng)問(wèn)老師,解析中reverse optimization的權(quán)重是怎么算出來(lái)的?答案沒(méi)有給過(guò)程,是直接通過(guò)程序跑出來(lái),為了辨析和mvo方法的區(qū)別嗎?
reading7 課后題15 老師,(1)這道題隱含了municipal bonds免稅的條件,所有政府類bonds都免稅嗎?(2)題目給了return,給了volatility,還需要計(jì)算utility嗎?謝謝!
R6原版書例題第2題,portfolio 5和無(wú)風(fēng)險(xiǎn)的組合計(jì)算sharpe ratio 時(shí)不用加權(quán)平均嗎,0.853×0.433+0.147×0
R5原版書例題第8題第二問(wèn),答案:積極的是超配低波動(dòng)性的、低配高波動(dòng)性的,到最后一句話消極的配置權(quán)重也是依賴于反張的波動(dòng)性,消極和積極描述的不是一個(gè)意思嗎
