金程問(wèn)答課件里risk neutral 考慮了當(dāng)前市場(chǎng),包括風(fēng)險(xiǎn)補(bǔ)償,老師講B選項(xiàng)又說(shuō)是風(fēng)險(xiǎn)中性,該如何理解?我蒙了
題干中的 credit spread和historical data 是不是對(duì)應(yīng) risk neutral和realword
前面有一題,說(shuō)Foreign currency defaults result from a lack of ability to print money in that currency, while local currency defaults are caused by a loss of power in printing currency or a deliberate trade-off between default and currency debasement.是對(duì)的,這里也說(shuō)Local currency defaults can occur even when countries can print more local currency, while foreign currency defaults are primarily driven by deliberate trade-offs between default and currency debasement.是對(duì)的。也就是deliberate trade-offs between default and currency debasement是適用于本幣也適用于外幣? 另,該題的A選項(xiàng)前半句,對(duì)應(yīng)上一題的答案“外幣違約result from a lack of ability to print money”,那這里說(shuō)“Foreign currency defaults typically occur due to constraints on printing currency”應(yīng)該也對(duì)?
component var =marginal var??價(jià)值,不是權(quán)重,為什么說(shuō)成分var是增量var的近似計(jì)算公式呢?
b問(wèn)組合風(fēng)險(xiǎn)最小時(shí),diversified var=新的成分var加總=邊際var0.0758M,跟表里的$228462完全不一樣,請(qǐng)老師解答
我覺(jué)得這里課件上的描述跟老師說(shuō)的不是一回事啊,按課件理解,Riding the Yield Curve,應(yīng)該是在利率是downward sloping的時(shí)候吧(也就是課件上說(shuō)price upward sloping),持有長(zhǎng)期債券多頭,未來(lái)利率下行有更高的資本利得(after the yield declines,賣掉roll out),感覺(jué)老師的例子有點(diǎn)奇怪,邏輯也更繞。’
老師問(wèn)個(gè)題外話,正反饋和負(fù)反饋怎么確定?負(fù)反饋是對(duì)市場(chǎng)好嗎
此處的drift和volatility都強(qiáng)調(diào)了年化。如果題中給的是非年化的數(shù)據(jù),需要進(jìn)行年化后使用嗎?

圖中說(shuō)的買方和賣方是否有問(wèn)題?
CDS的買方buyer,就好比銀行是買方,保險(xiǎn)公司是賣方。銀行支付費(fèi)用,為自己投放的貸款買了一個(gè)保護(hù)。 TRS的買方buyer,是總收益的接收方,是保護(hù)的賣方。 這CDS買方和TRS買方有點(diǎn)迷糊了,buyer有點(diǎn)疑問(wèn),老師幫忙梳理一下吧?
這里的數(shù)值對(duì)應(yīng)的我看教材應(yīng)該是年中違約,應(yīng)該是0.5,1.5,2.5吧
麥考利久期怎么計(jì)算呀?
