金程問(wèn)答你好,reading20課后第18題,c選項(xiàng)為什么不可以呢,scenario1的操作方式是增加convexity,c選項(xiàng)由于利率下降,如果convexity增加,那么漲的就會(huì)更多,所以c也是對(duì)的嗎?
老師,這里的shortfall magnitude怎么理解???
老師,請(qǐng)講解一下condor。為啥 short end profit if curve steepens, long end profit of curve flatten 為啥 增加曲度會(huì)獲利?
老師你好,Reading 30, 4題C,i是credit method。當(dāng)country A是residency jurisdiction,country B是source jurisdiction,答案是仍然交45%的稅,其中30%給B國(guó),15%給A。但是問(wèn)題是這個(gè)人目前住在B國(guó),他的收入都是在A國(guó)產(chǎn)生的。 而source jurisdiction的定義是外國(guó)人住在本國(guó),在本國(guó)產(chǎn)生的收益按照source jurisdiction才會(huì)給本國(guó)繳稅。 這個(gè)人的收入不是在B國(guó)產(chǎn)生的,B又是屬地過(guò)稅收,所以我覺(jué)得應(yīng)該是全部45%都交給A過(guò)才對(duì)。 同理,exempt mode,當(dāng)B國(guó)是source jurisdiction,為什么也要按照B國(guó)的稅率征稅。如果這樣的話,就是這個(gè)人如果住在B國(guó),不管他在那里取得的收入,他都要給B國(guó)征稅,這個(gè)我看課件沒(méi)有講的這么明確。
關(guān)于Dispersion和Convexity的關(guān)系中,介紹了3中portfolio。字面理解:分散化越大,凸性越大。為什么從圖2中所示,其中Bullet是在中期1個(gè)時(shí)間點(diǎn)支付,Barbell是在頭尾2個(gè)時(shí)間點(diǎn)支付, Laddered在6個(gè)時(shí)間點(diǎn)支付。為什么可以得到Barbell的分散性最大?課件123頁(yè)說(shuō)Ladder在時(shí)間維度有更有效的diversified,不是應(yīng)該理解為L(zhǎng)addered的分散度最大嗎?
老師您好,為什么兩個(gè)遞延稅率的FV計(jì)算公式不同?
老師,在個(gè)人IPS中,可以介紹下稅盾怎么計(jì)算嗎,老師上課基本沒(méi)講稅盾的計(jì)算,謝謝。
老師,這個(gè)公式,上課講tg*te是稅盾,正常稅盾公式:稅盾的價(jià)值=應(yīng)計(jì)稅費(fèi)用*稅率。而這里用兩個(gè)稅率相乘,不是計(jì)算稅盾吧。感謝。
原版書課后題第3題怎么理解三個(gè)observation?
R19第4題 為什么含權(quán)債券要用Effective Duration 這個(gè)知識(shí)點(diǎn)有點(diǎn)忘記了,請(qǐng)老師幫忙解答一下。 第5題 講義和原版書上都說(shuō) duration match的Cash flow comes from coupons and principal 為什么答案里說(shuō)是liquidating bond portfolio? 為什么cash flow match 不能算liquidating bond portfolio啊它也是到期就清倉(cāng)了啊。 謝謝老師!
請(qǐng)問(wèn)原版書 Reading 20 課後題 Q24. 中解答 C is correct. Winslow’s Statement VI is incorrect. Due to covered interest arbitrage, the relative attractiveness of bonds does not depend on the currency into which they are hedged for comparison. Hence, the ranking of bonds does not depend on the base currency of the portfolio. A is incorrect because Winslow’s Statement IV is correct. Inter-market trades should be assessed on the basis of returns hedged into a common currency. Doing so ensures that they are comparable. Neither local currency returns nor unhedged returns are comparable across markets because they involve different currency exposures/risks. 當(dāng)投資外國(guó)債券的時(shí)候,currency return 應(yīng)該也要考慮進(jìn)去吧? 請(qǐng)問(wèn)為什麼statement VI 是錯(cuò)的但是 statement IV 是對(duì)的?
請(qǐng)問(wèn)原版書中課後題 Q25: Determine the most appropriate immunization portfolio in Exhibit 2. Justify your decision. 答案是 Portfolio 2 1. Money Duration: Money durations of all three possible immunizing portfolios match or closely match the money duration of the outflow portfolio. 2. Convexity: Given that the money duration requirement is met by all three possible immunizing portfolios, the portfolio with the lowest convexity that is above the outflow portfolio’s convexity of 135.142 should be selected. 但是書上說(shuō) The conditions to immunize multiple liabilities are that (1) the market value of assets is greater than or equal to the market value of the liabilities, (2) the asset basis point value (BPV) equals the liability BPV, and (3) the dispersion of cash flows and the convexity of assets are greater than those of the liabilities. Portfolio 2 的 BPV是小於 Liability的。另外,上課的時(shí)候有說(shuō)要選convexity大的。滿足這兩項(xiàng)的應(yīng)該是Portfolio 1. 請(qǐng)問(wèn)為什麼答案是Portfolio2?
reading 19 section9 benchmark selection中,example11的第二個(gè)投資人,一個(gè)長(zhǎng)期私立大學(xué)捐贈(zèng),長(zhǎng)期流動(dòng)性需求少,而且不是強(qiáng)制負(fù)債,說(shuō)明整體風(fēng)險(xiǎn)接受度高(包括信用和利率),為什么就只考慮那個(gè)duration最高的那個(gè),BEUH duration不低,而且有high yield bonds, 不是也挺合適的么?
請(qǐng)問(wèn)這句話不是正確的嗎?
老師好請(qǐng)問(wèn)15年真題1-A,這個(gè)pension的RT是above average怎么理解,通常他有重要的負(fù)債要cover都是低于平均的RT,即使現(xiàn)在資產(chǎn)狀態(tài)好也應(yīng)該要以低風(fēng)險(xiǎn)去做吧,為什么是高于平均呢?
