Statement 2 If Jason were to purchase the annuity in 10 years rather than immediately, his annual income yield would be higher at that time than now。Statement 3 If Janice were to add a 10-year period certain option to her annuity, her income yield would be reduced when compared to not having the option, but it would be reduced by greater amounts the longer she waits to purchase the annuity.——這兩個(gè)為什么是對(duì)的,可否解釋一下?
Style box approach為什么tax inefficient
三級(jí) CME 用寬松的財(cái)政政策(通過發(fā)行長(zhǎng)期國(guó)債/政府債,增加赤字),不是應(yīng)該提高長(zhǎng)端利率嗎?為啥這題答案說(shuō)影響未知,這題該怎么理解?
老師,這里第四題。題目中說(shuō)緊縮性財(cái)政加貨幣政策會(huì)導(dǎo)致利率曲線變flat,但是緊縮性貨幣政策會(huì)導(dǎo)致長(zhǎng)端利率下降,然后寬松的貨幣政策才會(huì)導(dǎo)致短端利率上升,這樣才會(huì)flat甚至倒掛啊,這里不是應(yīng)該選B嗎
第一題只問key factors,不需要寫后面的不同點(diǎn)吧?
考試的時(shí)候需要把違反的哪一條寫出來(lái)嗎?還是像老師說(shuō)的那樣把具體違反的內(nèi)容解釋出來(lái)就可以。
能說(shuō)明一下Sortion ratio 的份子是什麼, 以及怎樣計(jì)算出來(lái)嗎?
Why is question 5b manager self identification incorrect?
請(qǐng)問第一題可以不可以選ZETA
首先,沒聽懂。因?yàn)榻Y(jié)果所以原因…不知道怎么理解的。轉(zhuǎn)換債券不就是利用差價(jià)嗎?選A不就行了?
這里為啥short put?
最后這個(gè)占比計(jì)算我沒看明白。數(shù)據(jù)對(duì)不上呢
不知道這個(gè)解題思路哪里錯(cuò)了:這里短端利率是下降的,說(shuō)明債券價(jià)格上升,應(yīng)該選短端能增加久期的選項(xiàng)。答案C中l(wèi)ong兩年的bond call option,隨著債券價(jià)格上升會(huì)行權(quán),行權(quán)后久期是縮短不是增加。還請(qǐng)老師看看
這里講解里講到,含權(quán)債券(無(wú)論call還是put)涉及到行權(quán)問題,會(huì)降低組合久期。這句話怎么理解?不考慮r變動(dòng)的方向也可以得出含權(quán)債券是降久期的結(jié)論么?
老師:是否可以說(shuō)成:當(dāng)gamma 最大時(shí),option is most sensitive to stock price movement?
