這里的broad EUR fixed income里的broad是指全市場的意思?
這道題不用從government bond能更好的cover liability的return、volatility來答么
這里在trading里面說的是,在percentage range的情況下,如果有任意資產(chǎn)的weight偏離corridor了,所有資產(chǎn)的weight都要回歸到原始的weight上,對吧?那考試時如果碰到這種題目,會單獨把rebalancing的方法告訴我們么?(做了前幾年的trading上午題,都是默認用的我說的這種方法的)
如何區(qū)分diversification和mutrally exclusive?
真題中的2016年的題目的第c問,為什么帶杠桿預期的波動率更低,一般不是有杠桿,風險更大,波動更大嗎?
Asset Allocation 請問實際上考試這樣寫可以嗎? 2017 Q8 A AO 1. The foundation has no liability-like payments, but only minimum spending and an AO approach can minimize the likelihood of decline; ALM 1. There is a fixed amount of EUR 5mn to distribute yearly, which can bee seen as an obligation to pay. B 1. Assets in the same asset class should be homogenous. Private equity and real estate are not the same; 2. Asset classes should be mutually exclusive. Broad EUR fixed income is not different from EUR-denominated government bonds. C 1. Emerging market equities should be added into the current portfolio; 2. Sharpe ratio of new asset class > Sharpe ratio of current portfolio × correlation 0.481 > 0.538 × 0.79 => 0.481 > 0.425 D 1. Because the investment horizon of the foundation is a perpetuity, Monte Carlo is suitable for investment over a multi-period; 2. Monto Carlo can compute a path-dependent terminal value since the foundation is rebalanced every six months.
請問“Provided each sub-portfolio lies along the same efficient frontier, the sum of the sub-portfolio will also be efficient” 中,CML與EF只有一個切點,而各子組合經(jīng)過MVO后均是各自Utility Curve與CML這條直線的切點,即數(shù)個optimal portfolios數(shù)個切點。 這些切點只可能在CML上, 為何這里寫lies along the same EF呢? 是否這里的efficient就是指optimal, 而lies along應(yīng)理解為“基于”而不是“沿著”或者“在EF線上”
老師您好,能否解答下第四題的選項c為何錯誤呢,答案也沒太看懂,不是太清楚below the target weight 或者above 是否都需要調(diào)整呢,和稅有何關(guān)系,感謝。
老師,Goal-based,Hedging-Return-seeking和Risk parity portfolio 這三種AA不是基于Mean Variance Optimization理論了是吧?因為最后總的Portfolio不在Efficient Frontier上了呀
asset自己和自己的協(xié)方差是不是等于自己的方差?
書后習題冊73頁第15題第二問。答案中使用CAPM的方法計算出了兩個Returns,分別是5.3%和9.7%,并在在答案中給出了這兩個數(shù)的計算過程。但是在這個過程中,用到了題干中說到的global market risk premium 5.5%,這個risk premium到底啥意思?為什么在計算global bond return和US equity return時都用這同一個risk premium?
老師請問如何理解第四題 讀不太明白您能幫我解釋解釋么謝謝
surplus這個efficient frontier AA怎么讀? 以surplus橫坐標為基準,每個資產(chǎn)在縱坐標的range表示這個asset的allocation嗎?efficient frontier 是一條線,如何轉(zhuǎn)化成這種面積圖?
請問這道題應(yīng)該怎么做?
老師這里是不是講錯了。Information ratio的分母是tracking error,也叫active risk。那不是應(yīng)該被動投資用volatility,主動投資更關(guān)注tracking error
