金程問(wèn)答
mock的29題的statement2 錯(cuò)誤在哪里？
你好，immunization不就是讓價(jià)格風(fēng)險(xiǎn)跟再投資風(fēng)險(xiǎn)，也就是duration跟investment horizon相等，這個(gè)題里何來(lái)在immunization之后還有reinvestment risk? Coupon無(wú)論大小都已經(jīng)被immunization了啊
第二題 B選項(xiàng) 為何利率和信用利差反向變動(dòng)（變化相互抵消）那么經(jīng)驗(yàn)久期是比有效久期更?。?
這里說(shuō)mutual fund會(huì)有規(guī)模效應(yīng)指的是什么呢？為什么mutual fund會(huì)有規(guī)模效應(yīng)呢？
對(duì)于第三種carry trade的方法，為啥還要花100元買債券回購(gòu)，而不是直接換匯投美元，這樣收益不是更高？
這里不太明白為什么說(shuō)excess return是考慮了duration difference呢？
老師好，我想問(wèn)一下，增加convexity方法里，long putable bond跟long put potion on bond有什么區(qū)別？或者實(shí)際怎么操作？
老師，麻煩問(wèn)下，27題是100000面值算一個(gè)合同嗎？
condor為啥要求四個(gè)債券的美元久期都相等呢？做空的兩只債券美元久期等于做多的兩只債券的美元久期不行嗎？
-0.8271怎么計(jì)算得來(lái)
老師 這里的Shift是解釋的non- parallel level change? 我一直都記成解釋平行移動(dòng)了，求確認(rèn)
老師能解釋一下下面三句話分別是什么意思么，都看不太明白
老師，這個(gè)case21題。降低不平行移動(dòng)的影響就是降conv這個(gè)邏輯不懂
原版書(shū)reading21 課后題的第8題的difference 2 和3 錯(cuò)誤在哪里？ Difference 1: Difference 2: Difference 3: Commodity producers and banks represent a higher proportion of EM indexes than of developed market indexes. Total or partial government ownership of EM issuers is common, which results in a higher average recovery rate for defaulted senior unsecured bonds for EM markets than for developed markets. Compared with developed markets, the credit quality of EM issuers tends to be more concentrated at the very high and very low por- tions of the credit spectrum.
