金程問(wèn)答固收,講義和沖刺筆記這里畫圈的講的是一個(gè)東西不,看暈了
Q20: reading12 習(xí)題17的B選項(xiàng)不大理解
Q19: 請(qǐng)問(wèn)書上Reading 12 習(xí)題18的解釋為什么說(shuō)first change? “An investor having an investment horizon equal to the bond’s Macaulay duration is effectively protected, or immunized, from the first change in interest rates, because price and coupon reinvestment effects offset for either higher or lower rates.” Excerpt From 2022 CFA Program Level III Volume 2 Derivatives, Currency Management, and Fixed Income CFA Institute This material may be protected by copyright.
請(qǐng)問(wèn)PBO和ABO中,計(jì)算退休后的PMT時(shí),是分別按照退休前的工資、CurrentWage乘以ServiceYears/100,那么這個(gè)ServiceYears指的是截至目前已經(jīng)工作的年數(shù)還是從現(xiàn)在到退休的工作的年數(shù)呢?
老師好,我想問(wèn)一下最后幾分鐘那6個(gè)strategy的表格里面,為什么long put option on bond future 和 long bond put option是decrease convexity呢?不是long了put/call option都會(huì)增加convexity嗎?謝謝
Reading12課后習(xí)題12不懂。 cashflow matching 會(huì)Mitigate the risk of non_parallel shift of interest rate curve。 是不是所有matching 例如 duration 等都可以mitigate?
Q17, 請(qǐng)問(wèn)對(duì)比兩個(gè)Portfolio, 怎么看哪個(gè)Cashflow reinvestment risk 高?
官網(wǎng)題,關(guān)于Excess spread return,問(wèn)題中假設(shè)no default losses occur,那么為什么答案表格中計(jì)算Excess spread要扣減Expected loss?
老師,麻煩講解下原版書中這個(gè)例題
關(guān)于Multiple liability immunization, 官網(wǎng)題,答案是推薦Portfolio2. 關(guān)于money duration of asset >= money duration of liability的條件,該題認(rèn)為money duration of asset ($2,609,442)和money duration of liability($2,609,700)這兩個(gè)金額是比較接近的,請(qǐng)問(wèn)老師金額接近有沒(méi)有比較明確的標(biāo)準(zhǔn),如果相差幾百可以認(rèn)為接近,那么幾千或幾萬(wàn)呢?
老師,原版書例題中第三問(wèn)pod*LGD要考慮holding period但是課后題中就有題目是不考慮holding period。新考綱到底是要考慮還是不考慮?
老師,麻煩講解下這里的第一題
官網(wǎng)題關(guān)于Excess spread return的問(wèn)題,EXR=spread0*t-SpreadDuration*delta Spread-POD*LGD*t,題干提示instantaneous,即持有期為0,所以有spread0*t項(xiàng)為0,為什么POD*LGD*t中的t不為0?
能否講一下這道題,沒(méi)看懂答案,謝謝。
利用利率互換調(diào)節(jié)久期;long固定利率,short浮動(dòng)利率,增加了久期;單純long固定利率不也是增加了久期,前者比后者成本高體現(xiàn)在前者需要大量支付本金去long固定利率bond嗎?謝謝
