金程問(wèn)答為什么這句話是錯(cuò)誤的?Easily tracked indexes in asset classes similar to that of an illiquid asset often do not represent the non-idiosyncratic risk of the illiquid asset very accurately.
選項(xiàng)C里的efficiency難道不是匹配了large size中slow down decision making這個(gè)缺點(diǎn)么

原版書459頁(yè)18題的答案,我覺(jué)得這個(gè)答案跟那個(gè)問(wèn)題就好像是答非所問(wèn)。麻煩老師解釋一下原理吧,謝謝
原版書387頁(yè)13題的答案,麻煩老師詳細(xì)講一下原理。謝謝
您好,前面季老師講原理的時(shí)候說(shuō)weight是固定一個(gè)收益率,然后不斷的發(fā)射不同的weight,最后找到一個(gè)在相同收益率下,風(fēng)險(xiǎn)最少的組合權(quán)重,但這里又說(shuō)這個(gè)w是通過(guò)那個(gè)公式算出來(lái)的,該怎么理解呀
您好,請(qǐng)問(wèn)一下,如果把cash當(dāng)做風(fēng)險(xiǎn)資產(chǎn)的話,那么cash就會(huì)有一個(gè)sd了嗎,如果看做無(wú)風(fēng)險(xiǎn),那么這個(gè)cash就沒(méi)有sd了是這樣嗎?
第四題的答案好長(zhǎng)啊。題目條件給了這句話,TEF’s current investment objective is to generate a real rate of return in excess of that required to fund ongoing distributions in accordance with TEF’s mission, with a maximum acceptable volatility of 16% per year, and to maximize the Sharpe ratio of TEF’s total financial assets . 能用這個(gè)來(lái)做判斷選B嗎,因?yàn)锳BC volatitiy都小于16%,而B(niǎo)的SR最大。
第四題,B錯(cuò)在哪里呢?EUR 5 billion不算是large嗎
A和B的相關(guān)性一樣都是0.7,而B(niǎo)的sharpe ratio 更高。選B更合適吧?是否重疊不是應(yīng)該看相關(guān)性嗎?
第二題,選B的原因?yàn)槭裁床皇沁@句話:Regulators impose a maximum limit of 10% of total reserve assets (which include matched and excess assets) on non-publicly traded securities.
recency bias 題目里面沒(méi)說(shuō)2008的crisis 是最近發(fā)生的吧。也不知道目前的年份。
為什么portfolio3會(huì)被認(rèn)為沒(méi)有portfolio2收益高 明明有更多的hedge funds
官網(wǎng)題 Tina Swan Case
這里反推E(R)的模型,為什么是知道w,σ,ρ反推E(R)呢,我知道了w不是直接就可以求出E(R)了嗎?全球市場(chǎng)組合不是直接就有現(xiàn)成的E(R)可以用嗎?而且他只有一個(gè)E(R)模型也不夠用呀
