金程問(wèn)答
這里B問(wèn)題的答案和老師的講解不一致啊
怎么去理解一個(gè)資產(chǎn)對(duì)組合variance的貢獻(xiàn)的計(jì)算公式呢。能否用直觀的解釋一下原理 方便我記憶
impact investing和thematic investing有什么區(qū)別？不太明白impact investing的含義。
老師，原版書(shū)課后有道CDS的題，Which of the following statements best describes how a single-name CDS contract is priced at inception? A. If the reference entity’s credit spread trades below the standard coupon rate, the CDS contract will be priced at a premium above par because the protection buyer pays a “below market” periodic coupon. B. If the reference entity’s credit spread trades above the standard coupon rate, the CDS contract will be priced at a discount to par because the protection seller effectively receives a “below market” periodic premium. C. Similar to fixed-rate bonds, CDS contracts are initially priced at par with a fixed coupon and a price that changes over time as the reference entity’s credit spreads change. 這道題為什么選B？ B是說(shuō)spread 大于coupon,B選項(xiàng)里“priced at a discount ”這明顯錯(cuò)了呀，應(yīng)該是premium吧？此外，AB選項(xiàng)都有“below market”這具體指什么？
heuristic constraints 和 Formal constraints的區(qū)別能說(shuō)明一下嗎？
Q1，security level這個(gè)怎么解釋
如何看出volatility變大
manager B 的factor return 0.2 x 0.20% + 0.05x 0.35% + 0.0 x 0.60% = - 0.025% 為什么沒(méi)有考慮在active return里？
哪里體現(xiàn)了sector rotator？
最后一題，能舉例說(shuō)明一下一個(gè)基金經(jīng)理是怎么做 timing exposures to factors的么？和調(diào)rewarded factor權(quán)重有啥不同？
第1問(wèn)，case中提到了factor，是否意味著用量化建模的形式進(jìn)行選股，因此是optimization。stratified sampling是定性分析，不涉及factors
為什么是portfolio overlay
老師，這個(gè)第一個(gè)式子是啥意思，我沒(méi)有看懂
Q3, 請(qǐng)問(wèn)價(jià)格加權(quán)的具體實(shí)施是什么樣的？為什么stock split會(huì)影響權(quán)重呢？能不能舉例說(shuō)明？謝謝
active risk為什么一定就會(huì)增加 而active return一定就會(huì)下降呢
