金程問(wèn)答筆記P138,虛曲線是effective duration這個(gè)表達(dá)是什么意思?老師說(shuō)這條虛線是callable bond又是什么意思?不太明白這些表達(dá)。

Cash reserve fund: deposit of cash provided to the SPV from the proceeds of the sale of the loan pool by the entity seeking to raise funds.如何理解這句話?謝謝!
1.Agency securities: CMOs are created from pools of passthrough securities. 我理解,這句話中的CMO現(xiàn)金流來(lái)自 pools of passthrough securities,pools of passthrough securities的現(xiàn)金流來(lái)自于pool of mortgage loan,對(duì)不? 2.Non-agency securities: CMOs are created from unsecuritized mortgage loans. 我理解,這句話中的CMO現(xiàn)金流,直接來(lái)自pool of mortgage loan,因?yàn)閘oan沒(méi)有證券化unsecuritized,對(duì)不?
P148-153的內(nèi)容漏掉了嗎?
講義P242,題目沒(méi)有說(shuō)明par value是100還是1000,如果帶入1000計(jì)算,結(jié)果一樣嗎?
Dollar duration并不滿足duration得定義式了,因?yàn)槌肆艘粋€(gè)P_full,變成delta P/delta y了。這個(gè)久期的定義式?lta P/delta y怎么理解呀,我怎么覺(jué)得這就是修正久期的另一種表示方法。。。
這里的parallel shift我不知道我理解的對(duì)不對(duì)。Dp=W1D1+W2D2,既然是直接相加,證明所有部分的分母是相同的,也就是delta y是相同的,所以從圖像上來(lái)看就是平移了。。。。個(gè)人理解,是這個(gè)意思嗎

Prepayment risk,我理解是pass-through security的contraction risk和extension risk Prepayment rate,我理解是Mortgage loan的提前償還速度 不知我的理解,對(duì)不?
講義的P232中,久期的第三條結(jié)論(短期投資,價(jià)格占據(jù)主導(dǎo)),為什么說(shuō)“當(dāng)市場(chǎng)利率上升的時(shí)候,投資回報(bào)會(huì)有損失呢"? 是因?yàn)閭瘍r(jià)格一直處于高位的原因嗎?
