為什么putable更profitable?
不就是因為participants are entitled to receive a monthly benefit，所以才應(yīng)該用cash flow matching嗎？還有，答案中說的 The threshold of 5% (of assets greater than liabilities) is exceeded in both plans; the Lawson portfolio has a surplus of 7.7%, and the Wharton portfolio has a surplus of 11.8%.哪里有提到，題目信息有給嗎，自己腦補(bǔ)的吧
stratified sampling approach 不是 equity approach嗎？和enhanced indexing有什么區(qū)別？ synthetic strategy using a total return swap成本會低嗎
老師，這個2，modify D也是錯的吧
fixed income 官網(wǎng)題。這題我是排除法做對的，請老師再詳細(xì)解釋一下，謝謝。
為什么consideration 2就沒有問題呢？情景分析里增加極端情況就是為了測試最極端的損失，但是正文又講假設(shè)和過去經(jīng)濟(jì)危機(jī)的后果一樣。
因外幣升值，總體收益不應(yīng)該增加嗎，為啥不選A
這個題錯了吧老師。A對吧…
老師您好，關(guān)于固收example29的這個long5年的cds 老師講的是不是講反了，應(yīng)該是（0.99244-.99066）*10000000，因為longcds不是應(yīng)該賺錢了嗎？
請講解一下
在計算immunization的時候，是默認(rèn)以萬元為最小金額嗎？還是說題目沒說就不考慮?
Measurement error for Asset BPV can arise even in the classic passive immunization strategy for Type I cash flows, which have set amounts and dates. Asset liquidity can become a risk factor in strategies that add active investing to otherwise passive fixed-income portfolios and would not be applicable here.老師您好，請問為啥active investment有流動性風(fēng)險？這句話怎么理解呢
請問第二點中，在times of stress的時候為什么要aid in positioning the portfolio
請問bond隨著發(fā)行的時間越長，liquidity應(yīng)該越低。但是為什么隨著時間的推移，離到期時間越短，liquidity反而上升了呢？
A change in interest rates has the same effect on a risk free bond as it does on a risky bond
