老師,這個公式,上課講tg*te是稅盾,正常稅盾公式:稅盾的價值=應計稅費用*稅率。而這里用兩個稅率相乘,不是計算稅盾吧。感謝。
老師,這道題中兩年期的債券在第一年年末時候的YTM,直接用了一年期債券的YTM,但是這兩個債券的Coupon rate等都不一樣,這樣是不是有點不合理呢?

R19第4題 為什么含權債券要用Effective Duration 這個知識點有點忘記了,請老師幫忙解答一下。 第5題 講義和原版書上都說 duration match的Cash flow comes from coupons and principal 為什么答案里說是liquidating bond portfolio? 為什么cash flow match 不能算liquidating bond portfolio啊它也是到期就清倉了啊。 謝謝老師!
請問原版書 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. 當投資外國債券的時候,currency return 應該也要考慮進去吧? 請問為什麼statement VI 是錯的但是 statement IV 是對的?
請問原版書中課後題 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 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,上課的時候有說要選convexity大的。滿足這兩項的應該是Portfolio 1. 請問為什麼答案是Portfolio2?
reading 19 section9 benchmark selection中,example11的第二個投資人,一個長期私立大學捐贈,長期流動性需求少,而且不是強制負債,說明整體風險接受度高(包括信用和利率),為什么就只考慮那個duration最高的那個,BEUH duration不低,而且有high yield bonds, 不是也挺合適的么?
請問這句話不是正確的嗎?
老師好請問15年真題1-A,這個pension的RT是above average怎么理解,通常他有重要的負債要cover都是低于平均的RT,即使現(xiàn)在資產狀態(tài)好也應該要以低風險去做吧,為什么是高于平均呢?
筆記說inflation上升,effect on stock price下降,之前說溫和的inflation對股票的影響是positive的,具體是怎樣的?
老師啊老師,請問ST model,要調整流動性和融合度,這個流動性是先加權最后再加上呢,還是在計算segmentation和integration的RP時候,就先各自加上,然后加權? 我真的自閉了,我在case題里見過先直接算加權,最后加上illiquidity的,百題經(jīng)濟學case4,第四題;但是真題先調整流動性再加權的。 請老師解答,這都什么人間疾苦啊………………
原版書R15課后題第一個CASE(WORDEN TECH)的第一問return requirement答案給的是Y,但課上總結的規(guī)律是underfunded情況下return目標=discount rate of liability+excess return,感覺描述的是X……
原版書后習題reading 17的第三小題,conclusion2和3分別是什么意思?
老師您好,這道題的B問中,答案里使用三種形式計算required rate of return,我想知道第三種calculation method為什么這樣計算。inflation為什么加到spending rate上而非management fee上,說反映exacting timing of CFs,是因為spending rate和inflation發(fā)生在這一年中,而management fee在年尾才計算嗎?謝謝。
