老師這一段什么意思As long as none of the factors used in a factor-based VCV model are redundant and none of the asset returns are completely determined by the common factors, there will not be any portfolios that erroneously appear to be riskless. Therefore, a factor-based VCV matrix approach may result in some portfolios that erroneously appear to be riskless if any asset returns can be completely determined by the common factors or some of the factors are redundant.
通過Labor和labor/productivity增長求得的GDP增長,是real還是nominal值?
第二問關(guān)于swap的機(jī)制有些疑惑。 比如這里我知道south American yield will decrease, and bond的價(jià)格會(huì)上升, 想要long south American bond. 如果我都receive fixed-rate on south American bond, 還怎么從該債券價(jià)格上升中獲益呢? 還是說要從yield角度考慮,因?yàn)閟outh American bond yield會(huì)下降,所以想要receive fixed-rate 來保證收到的rate 不受yield 下降影響? swap里的fixed-rate, 到底是什么的rate???coupon rate? yield rate?
與private equity和private real estate相比,絕對回報(bào)對沖基金在分散該基金主要的股票風(fēng)險(xiǎn)方面具有更大的潛力。絕對回報(bào)對沖基金的股票貝塔系數(shù)通常低于private equity和private real estate 不太理解第一題,為什么對沖基金比房地產(chǎn)還能分散股票的風(fēng)險(xiǎn)
第一問為什麼不考慮portfolio價(jià)值的增長率6.5%後再x 2% yield?
為什么求出B了還要往前折現(xiàn)啊,initial purchase price不是B債券的面值么
前面的slowdown已經(jīng)是倒掛的曲線了,然后在contraction蕭條期時(shí),短期下降,長期上升,不應(yīng)該是更平坦嗎?為什么會(huì)是陡峭呢?
hedge fund不抗通脹的原理能否說明一下
老師,關(guān)于執(zhí)行落差,PPT上大概在426頁Implementation shortfall (IS) = Paper portfolio return – Actual portfolio return,使用return做差,然而在沖刺筆記上135頁,執(zhí)行落差都是將直面投資組合(基準(zhǔn))的價(jià)值和實(shí)際投資組合的價(jià)值做差進(jìn)行比較,return和價(jià)值(value)這肯定是不同的,到底以哪個(gè)為準(zhǔn),這種差別,考試真讓算執(zhí)行落差,該用哪個(gè)? 以及如何統(tǒng)一起來理解?謝謝
security lending中如果抵押物為現(xiàn)金,lender可以有fee + 再投資收益兩筆收入,但是如果抵押物為高質(zhì)量債券,lender只能享受 fee,其余的要作為rebate rate返還,這里完全不考慮扣除掉換算成cash可能產(chǎn)生的再投資收益對嗎?這樣少了一筆收入會(huì)不會(huì)很不公平?那豈不是所有l(wèi)ender都更傾向于現(xiàn)金作為抵押物?
這塊分了兩塊內(nèi)容 一塊是wealth 一塊是各種資產(chǎn),其實(shí)兩者概念非常相近,CFA的用意是什么?又怎么區(qū)分理解比較好?相信很多考生都容易混淆這兩個(gè)概念
Ex post risk不是會(huì)低估ex ante risk么
上面組合方差的計(jì)算公式應(yīng)該也需要加上殘差的方差吧?
volatility clustering視頻中老師解析沒聽懂,請?jiān)敿?xì)解釋一下,謝謝
我這樣的回答是不是得不到什么分。。。1. Increase in exported (imported) goods and services appreciates (depreciates) domestic currency because the demand for domestic currency relative to the foreign currency is higher (lower). 2. Increase in capital inflows (outflows) appreciates (depreciates) domestic currency because the demand for domestic currency relative to the foreign currency is higher (lower).
