請老師說下I spread 和swap spread 的公式?哪個減哪個
???????????????????????? ≈ ????????????0 ? ???????????????????????? × ?????????????。邏輯是預(yù)期的超額等于期初-變化,但是等號后面的兩者概念不同,一個是spread,一個是DTS,這兩者相減是什么意義?為什么不是???????????????????????? ≈ ????????????0 ? ??????????????為什么不是???????????????????????? ≈ ????????????0 *duration? ?????????????*duration?我覺得要乘duration就前后都乘,要不乘就都不乘,一個乘一個不乘沒有可比性呀。
直播課講的這個example,為什么第一步只算了fixcoupon的部分,為什么不考慮他一開始sellCDS收到or付出的CDSprice的部分?
1. Which of the following portfolio positioning strategies offers maximum gain if the interest rate view is realized? Buy a 30-year payer swaption and a 2-year bond call option. Buy a 30-year receiver swaption, and a 2-year bond put option. Sell a 30-year payer swaption and write a 2-year bond call option. 請問這題為什么不能選C,也是買長期賣短期bond,還能獲得期權(quán)費,gain最大化
老師您好,請問官網(wǎng)這道題為什么要除以3?正確答案應(yīng)該選什么?謝謝
能否解釋一下邏輯和理由:(1)a bond with higher convexity might be expected to have a lower yield-to-maturity than a similar-duration bond with less convexity. (2) All else equal, bonds with longer durations have higher convexity than bonds with shorter durations.
老師好,固收真題trade 2,買入5% coupon rate的債券,賣出一個零息債券,不是增加了duration嗎?收5%支0%,可是答案解析的效果是降duration,沒太明白
?請問yieldcurve的波動性策略究竟怎么做?1.不知道方向,只預(yù)測波動性上漲時,怎么操作?為什么?只預(yù)測波動性下跌時,怎么操作?為什么?2.PPT161和162中,一頁都時增加久期的,一頁都是降低久期的操作,這兩種操作分別適用于哪種波動性的策略?
老師,你好,fixed income 原版書reading 13中,對于static yield curve strategy中的第一種方法long futures position is similar to rolling down the yield應(yīng)該如何理解?rolling down the yield是賣短期,買長期;而long futures position是買入期貨合約持有到期,感覺應(yīng)該是更像buy and hold,從來能夠體現(xiàn)賣短期,買長期的相似之處呢?
?關(guān)于bullet和barbell的比較:1.PPT只假設(shè)了bullet在maturity中間的位置,以此推導(dǎo)出curve非平行移動時組合duration受影響最小,但是bullet也可能集中投資在任何一個時期,比如非常短期或者非常長期的時刻,這種情況下受到的影響是不是很大?2.barbell組合中,發(fā)生非平行移動時比如steeper,短期投資價格上升,長期投資價格下跌,綜合影響是不是會互相抵消?導(dǎo)致barbel受到的影響很???3.如果1、2討論的兩種情況成立,會不會導(dǎo)致barbell的risk反而比bullet???
老師請問A選項和B選項哪里錯了,DM是什么
這題算出來是0.129997怎么就成了13bps怎么就是0.0013了?
老師您好,不是說investment-grade對interest rate更敏感,對credit spread不敏感嗎,答案要怎么理解
老師,看到百題答案里有一句話An indexer (full replication approach) or enhanced indexer would keep the duration matched to the index. 作為AO的管理方式,pure indexing和enhanced indexing都要確保久期與基準(zhǔn)完全一致嗎?
Key rate duration is one established method for measuring the effect of shifts in key points along the yield curve. In this method, we hold the spot rates constant for all points along the yield curve but one. 老師,這句話怎么理解?
