老師好,不太理解這道題目里為什么is incorrect in her description of pricing differences between the spot and futures markets based on accrued interest. 請(qǐng)?jiān)敿?xì)解釋Bond Futures的報(bào)價(jià)和Spot Bond Market的報(bào)價(jià)有什么相同和不同之處以及聯(lián)系?!癟ypically, bond futures are quoted with pricing that reflects interest accrued since the last coupon payment. Therefore, in markets where spot prices are quoted “clean” rather than “dirty,” there can be some disconnect between spot and futures prices.”為什么題目中這么陳述是錯(cuò)誤的?

Q4我直接應(yīng)用之前學(xué)的結(jié)論:“當(dāng)前利率高的貨幣未來(lái)會(huì)貶值”,結(jié)合讀題得到的遠(yuǎn)期匯率與即期匯率判斷的“預(yù)計(jì)NZD未來(lái)貶值”,判斷出當(dāng)前NZD利率高,而不用利率平價(jià)公式,可否?

老師你好,“Implied volatility is higher for lower strike prices than for higher strike prices; therefore, out-of-the-money put options will generally be more expensive than out-of-the-money call options.”為什么可以推出價(jià)外看跌期權(quán)比價(jià)外看漲期權(quán)更貴?然后有怎么更選項(xiàng)B聯(lián)系起來(lái)?選項(xiàng)B:Using out-of-the-money options to hedge is more expensive than establishing a long position with out-of-the-money options,為什么價(jià)外期權(quán)對(duì)沖比long一個(gè)價(jià)外期權(quán)更貴? 不太理解這道題在考什么,請(qǐng)解釋。
expectation定價(jià)和no- arbitrage定價(jià)是不是前者是關(guān)注點(diǎn)在投資者的風(fēng)險(xiǎn)中性上,采用了計(jì)算pai去得到定價(jià),后者則是關(guān)注點(diǎn)在市場(chǎng)無(wú)套利上,不用pai而用hedge ratio去得到定價(jià)?如果針對(duì)同一個(gè)期權(quán),題目沒(méi)有明確指明要哪種方法的話是不是算出來(lái)的結(jié)果應(yīng)該會(huì)是相同的?然后如果市場(chǎng)有套利的情況下二者結(jié)果會(huì)有不同?以及本題中說(shuō)到的“the stock price will either be 56 or 46”這里的“either”為什么不能理解為價(jià)格上升下降的概率各為50%?難道是說(shuō)這個(gè)“either”表述的只是表達(dá)會(huì)有兩個(gè)node?
