第三題,Difference 3: Compared with developed markets, the credit quality of emerging markets issuers tends to be more concentrated at the very high and very low portions of the credit spectrum. 正確的表述應(yīng)該是什么?謝謝
這題出錯(cuò)了吧,利率變動(dòng)不應(yīng)該是0.16么
這道題完全沒有聽懂,老師能麻煩再解釋一遍么?
structural model和reduced form model的區(qū)別有2: 一是前者能準(zhǔn)確說明default的原因是A
第三題,首先,crossover sector是什么?然后C的邏輯是什么,經(jīng)濟(jì)不好對短期債的影響肯定大過長期債吧,買久期更短的債券不是踩雷嗎?
老師我想請教一下關(guān)于 callable bond 還有putable bond的問題。1.從文中所知long call option會提高duration,long put option 會降低duration。 那么long callable bond會提升duration,long putable bond會降低duration嗎?2如果利率下降,有 callable,putable,還有option free bond,為什么要選擇free bond。老師當(dāng)時(shí)候說債券含權(quán)都會降低duration。怎么理解?
老師,第三問的策略,如果寫long 10-year CDS,short 5-year CDS,是不是錯(cuò)了?long CDS是不是賣保護(hù)了?應(yīng)該long protection for 10-year CDS這樣嗎?
第三題A選項(xiàng)是什么意思呢
CDS spread變大,不是代表風(fēng)險(xiǎn)變大,所以要買CDS保護(hù)去short risk嗎,為什么卻說是賣保護(hù)呢?nn然后long CDS就理所當(dāng)然地引出了CDS價(jià)格上升,是為什么就CDS價(jià)格會上升了呢?難道是因?yàn)橘I的需求大了就價(jià)格上升嗎?nn(這一題的官網(wǎng)講解真是把人看得好暈乎??)
第一題答案中說,if the portfolio has a liability to meet, then the liability becomes the benchmark。這句話怎樣理解啊?是說如果是liability driven的組合,也有benchmark就是這個(gè)負(fù)債本身?這里的benchmark和return-based的benchmark是一個(gè)概念嗎
第三題文章說”Market value of liabilities portfolio is USD 115 billion; portfolio has a market value of about USD 120 billion” 因此判斷是BPV asset 大于BPV liability。所以 利率下降時(shí)候 應(yīng)該underhedge; rates上升時(shí)候應(yīng)該overhedge吧?答案完全是從 BPV asset小于 BPV liability 角度,應(yīng)該是錯(cuò)了吧
老師,利率變化我算出來是16%,直接帶進(jìn)去,算出來的數(shù)字正好大了100倍、還是不太明白 2.33*根號下21*1.5%=16%哪里錯(cuò)了
請問買入保護(hù)到底是long CDS還是short CDS?
r14提到的reduced form medels和structural credit models感覺比較抽象,能否給具體講講?謝謝
2\The CDS spread decline of 0.15% leads to a new CDS contract price of 94.75 per 100 face value (=1 – (EffSpreadDurCDS × ΔSpread) or (8.75 × 0.60%)). The protection buyer (short risk) position therefore realizes an approximate mark-to-market loss of €131,250 (=(94.75 – 93.4375)/100 × €10,000,000) because of the 0.15% decline in CDS spreads.這里為什么是8.75 × 0.60%,0.60%是哪里來的?
