第一題我想多了,答成了bull call spread去建構(gòu),因?yàn)轭}目中說了她does not want to sell her employer’s stock,所以排除了用protective put, 因?yàn)橘I了一個(gè)看跌期權(quán),用這個(gè)策略如果行權(quán)不就得把這個(gè)股票賣出去了么。請問下這個(gè)思路合理嗎
老師想問一下,這道題是怎么看出來是equity return payer, floating rate receiver的?是因?yàn)榭蛻鬶olds QQQ opsition嗎?
老師您好,請問credit rating migration can cause spread risk to become realized.這句話啥意思。With respect to risk considerations for investment-grade bonds, Larent is most likely correct with respect to spread risk. Spread risk is a function of credit migration. For investment-grade bonds, the risk of credit rating migration (credit deterioration) is greater than the risk of actual credit loss. Accordingly, credit spread volatility, as opposed to outright credit default loss, is a more relevant consideration as it relates to investment-grade bonds. Spread duration measures the credit spread volatility risk in a portfolio of investment-grade bonds.
why?。洌铩。?use ATM PUT for BUYING PUT FOR BEAR PUT here? not using OTM PUT?
這道題沒有看懂,美元更值錢了,不應(yīng)該收到的美元更少嗎? 這里為什么說他要增加收到的錢?而且basis 不是加在非美元的一端嗎?
Q4,需要提forward rate (1.9427)這個(gè)嗎?我直接說forecast spot rate 比現(xiàn)在的spot rate低所以要對沖,行不行?
這里第二大步的第一步調(diào)整完相當(dāng)于把bond allocation 調(diào)成了50%,但是第二小步的調(diào)整不是又把在bond allocation 調(diào)的低于50%了?
第3題的問題題干不太明白。要對沖200M的日元資產(chǎn),相當(dāng)于200M的日元是y吧?現(xiàn)在問需要多少日元去對沖,就應(yīng)該是y/b1,然后得出200/0.8=250M吧? 為什么對沖200M的日元資產(chǎn)成了x了?
第5題,put80%是執(zhí)行價(jià)格是當(dāng)前價(jià)格的80%,put90%是執(zhí)行價(jià)格是當(dāng)前價(jià)格的90%,那么期權(quán)費(fèi)90%的put應(yīng)該比80%的期權(quán)費(fèi)要高才對吧?同樣,120%的call應(yīng)該也比110%的call的價(jià)格高才行吧? 比如我90元賣同樣的東西,肯定要比80元的期權(quán)費(fèi)要高才行吧?這里是不是反了?
怎么去判斷應(yīng)變量是USD的標(biāo)準(zhǔn)差,還是EUR標(biāo)準(zhǔn)差,如果給的Exchange Rate σ是(RUSD/EUR),那這里的應(yīng)變量是不是就是USD標(biāo)準(zhǔn)差了
老師,這里請講解,沒明白這個(gè)例題
第五題,因?yàn)槭乔笫找媛?,我可能?huì)天然去想用 Rdc=(1+Rfc) (1+Rfx)-1這個(gè)思路去算。但是題目中老師是推薦算本幣的絕對損益以后,再求出本幣收益率。請問1)這道題用Rdc=(1+Rfc) (1+Rfx)-1這個(gè)思路去算可以嗎,應(yīng)該怎么算? 2)遇到真題問calculate rate of return from currency hedging的時(shí)候,我是應(yīng)該都用題目說的這種計(jì)算出損益amount而不是Rfc/Rfx的思路嗎?
Q3,可以按照long base currency,在contango的情況roll yield為負(fù)理解嗎?這里因?yàn)槭莝hort based currency,又是backwardation,所以也是負(fù)roll yield.
沒明白long risk reversal是long OTM call和short OTM put, 其中OTM call是正的delta, short OTM put也是正的delta,所以做long risk reversal的delta一定是正的不為0,那為什么risk reversal還被稱為是一種delta-hedged trading strategy呢?
2024年模考A Session1, case5,這個(gè)第二題的份數(shù)是怎么求出來的?原理是什么?麻煩老師解答一下,謝謝!
