Reading 3課后題第8題,Country Y處于slowdown phase,短期應(yīng)該是inverted吧?沒理解答案說短期會(huì)steepen的原因。
百題第二個(gè)case GK 模型中提到repurshase yield是什么意思?強(qiáng)化班老師說這里應(yīng)該是加減股數(shù)的變動(dòng)看是增發(fā)還是回購,如果增發(fā),收益率下降,如果回購,收益率上升,那repurshase yield是表明回購帶來的收益率變化?正數(shù)就是+,負(fù)數(shù)就是減少?
27:40 請(qǐng)問 根據(jù)η的定義,這個(gè)說的是unexpected component of return in period t,即η才是shock 那么,最后湊出來的(η_t平方 - σ_(t-1)平方): 即t時(shí)刻的shock - (t-1)時(shí)刻的波動(dòng)率是什么東西?咋還能這么寫?時(shí)間點(diǎn)都不一樣,怎么能隨便減呢?
密卷中cme的這道題,要求長期return,我想的話就是取GDP的增長率就是長期的equity return了,為什么這道題的答案中還加上了dividend return?。??
老師好,請(qǐng)問密卷第一大題第四小題,為什么增長和通脹會(huì)減少得少一些?
我在CFA網(wǎng)站上看到這么一句話:“One bias results from the use of appraisal data in the absence of market transaction data. Appraisal values tend to be less volatile than market determined values for identical assets. As a result, measured volatilities are biased downward and correlations with other assets tend to be exaggerated.”為什么關(guān)于correlation的部分是錯(cuò)誤的呢?
麻煩老師講一下B和C選項(xiàng)
老師,請(qǐng)問這道題材料中的”Sharpe ratio for GIM and emerging small-cap equity: 0.31”表述是不是錯(cuò)了,這個(gè)不該是GIM的Sharpe Ratio嗎,為什么還會(huì)有emerging small-cap equity?
百題case3的第四題,我認(rèn)為高頻數(shù)據(jù)會(huì)有異常值,會(huì)高估相關(guān)性,就是本來不相關(guān),但是數(shù)據(jù)顯示相關(guān),所以為啥這個(gè)是低的相關(guān)性,不懂,謝謝
老師,這道官網(wǎng)題是不是題目出錯(cuò)了?
CME歷年真題最后一個(gè)案例最后一問,為什么從capitalflow來看不是升值呢?資本賬戶投資減少,說明經(jīng)常賬戶增加,貿(mào)易順差,本國貨幣需求增加從而升值,印象中外匯好像是受經(jīng)常賬戶影響更大?
CME 原版書 144頁,Question 3: Growth in other countries is likely to increase as the tax cut stimulates demand for their exports and that increase in turn generates additional demand within their domestic economies. --- 減稅應(yīng)該是減少我國出口,但是會(huì)刺激別國出口和別國經(jīng)濟(jì),對(duì)嗎?
老師,這里計(jì)算%ΔE = nominal earnings growth = real earnings growth + long-term inflation + corporate premium,為什么要加多corporate premium? 沒印象公式里有這部分呢

CME 金程PPT 115頁,最后一點(diǎn):為什么收益預(yù)期高3%對(duì)波動(dòng)率影響是一樣的?
