金程問(wèn)答第七題為什么用sp500的index乘以mini的multiplier 這不兩個(gè)東西嘛怎么能乘
Reading 18第1題,position sizing和reward factor weighting都是alpha skill吧?這三者特征是什么?
第2題的reason 3,我個(gè)人對(duì)"fully express short ideas"有些疑惑,我覺(jué)得這個(gè)表述在long/short中是有點(diǎn)問(wèn)題的,因?yàn)檫@個(gè)策略的short部分是通過(guò)做空高估股票賺取alpha的,但是投資者并沒(méi)有對(duì)beta產(chǎn)生什么觀點(diǎn)進(jìn)而來(lái)通過(guò)beta獲利,相反long/short把beta都對(duì)沖掉了,這種情況為什么可以說(shuō)是fully呢,我個(gè)人感覺(jué)是partially,感謝老師解答
比例低于10%,能達(dá)到效果嗎?engagement中強(qiáng)調(diào)是大股東傾向于去做
Price weighting的index提供最好的分散效果 那smart beta中的diversification oriented strategy為什么不是price weight而是equally weighted
精 L3V3 P362, why does a negative coefficient on the Size factor indicate a large-cap bias?
L3V3 P202. I'd like to ask something about the tracking error and transaction cost. (1) If the tracking error measures the divergence in portfolio price and benchmark price, does that mean whatever causes the price difference could affect the tracking error? (2) In the diagram, why is the "tracking error gross of trading cost" continuously declining when both tracking error and transaction cost are increasing? (3) How to guarantee a convex U-shape but not a concave U-shape? If the first security purchased for the portfolio is illiquid, then transaction cost dominates and tracking error should increase.
Q7,在現(xiàn)實(shí)生活中 期貨產(chǎn)品的價(jià)格是有multiple的么?股票現(xiàn)貨的話,EPS*multiple=股價(jià),也就是股價(jià)里包含了multiple。期貨是不一樣么?
上午題equity部分第128頁(yè)CASE的B問(wèn),能否再梳理一下?另外return-basedreason不是應(yīng)該看return來(lái)源是哪些再看是什么風(fēng)格嗎?為什么是看holdingweight?
reading16視頻里面的關(guān)于pricedweighted的方法中計(jì)算分母X是不是算錯(cuò)了?不應(yīng)該是2.33么?
權(quán)益官網(wǎng)題,Lisette Langham Case Scenario case, 為什么alpha不對(duì)呢?看不懂答案解析
老師,你好,原版書(shū)reading 18的example 5總的第一問(wèn)和第三問(wèn)中都問(wèn)到關(guān)于absolute risk,而且都是考慮在組合中多加入cash.但是為什么第一問(wèn)的解答是absolute risk上升;而第三問(wèn)確是absolute risk下降呢?absolute risk的計(jì)算公式是不是就是各類資產(chǎn)之間的權(quán)重與convariance之積相加嗎?
精 老師好,R18中Q5,想探討一下。按題干的意思,active risk和active return是可以割裂來(lái)單獨(dú)增加減少的,想了解一下有沒(méi)有形象一點(diǎn)的操作實(shí)例呢?一個(gè)portfolio構(gòu)建好了之后,調(diào)整active risk和active return為啥不是同步的呢?比如原來(lái)是大盤小盤各50%,風(fēng)險(xiǎn)和收益都相對(duì)較高,但調(diào)整為100%大盤的時(shí)候,風(fēng)險(xiǎn)和收益其實(shí)都同步降低了
C選項(xiàng)怎么感覺(jué)沒(méi)學(xué)過(guò)那種 trap
請(qǐng)問(wèn)R18原版書(shū)例題3的材料中的He is highly sector and size agnostic.是什么意思?
