老師我想問一下Reading16課后題的第5題,關(guān)于currency basis swap,為什么US investor最后收到的payment是Euros only。另外basis swap不是互換了本金之后,之間的利息不netting嗎?謝謝
衍生部分casebook2012年的ABC三道題目怎么理解?謝謝
老師,第十七章筆記和教材上有這樣一句關(guān)于Technical Analysis的話:Past price data can predict future price movement and because those prices reflect fundamental and other relevant information, there is no need to analyze such information. 我不理解為什there is no need to analyze such information?最后以胡話中的such information又指的什么呢?
P393 Executing a hedge這個(gè)案例的hedge2我沒看懂,把思路梳理了一下,請(qǐng)老師看下對(duì)不對(duì),以及對(duì)hedged return的計(jì)算對(duì)不對(duì)。還有,題目說認(rèn)為3月后spot rate會(huì)下降,但是forward point>0,說明這個(gè)有套利空間?也就是HKD/EUR forward被高估了,需要被賣出。三個(gè)月后的spot被低估了,可以買入。是嗎?這個(gè)和要不要hedge是一樣的嗎?(因?yàn)閒orward rate大于expected spot,所以要hedge,即通過sell forward來hedge)
“write a covered call”是不是就是long stock+short call?感覺這個(gè)表述有點(diǎn)迷惑,因?yàn)閏overed call=long stock+short call,write a covered call我以為是short stock+long call。但是看答案又不是。P251 Example3 Q1
老師,您能否詳細(xì)解釋一下這句話的原理: If we long a stock and short 1/delta calls the value of the portfolio does not change, when the value of the stock changes. We make money by buying the stock and lose money by selling the call options while the value of the portfolio remains unchanged. This portfolio is referred as a delta-neutral portfolio. 1)為什么通過delta-neutral hedging可以做到改變stock的values,卻不改變portfolio的value? 2)為什么可以認(rèn)定make money by buying the stock and lose money by selling the call options?
請(qǐng)問在uncovered interest rate parity成立時(shí), carry trade是不能進(jìn)行的對(duì)嗎
用short call option的方法來做hedging,從老師的圖形看,是保留了上漲空間,這和直接用靜態(tài)的hedging不同,這樣理解對(duì)嗎
關(guān)于外匯標(biāo)注的問題。課程中老師提到,外匯計(jì)價(jià)法一般都是DC/FC,其中DC是pricing currency, FC是based currency。但是176頁P(yáng)PT中,針對(duì)base currency's real exchange rate appreciates的情況,卻是在討論DC 升值,F(xiàn)C貶值的問題。請(qǐng)老師解答(1)176頁P(yáng)PT中到低怎么理解。(2)當(dāng)題目未給出計(jì)價(jià)表示方式時(shí),默認(rèn)的based currency是本幣還是外幣?
老師您好, 這是衍生品ppt94的題, 我問一下這里為什么會(huì)除100呢?謝謝
請(qǐng)?jiān)敿?xì)解釋一下第三問 多謝
casebook56頁題目A的第二問,計(jì)算current exposure from selling the put options的時(shí)候,為什么用的是spot price 而不是 exercise price?
P38頁,crashophobia:X執(zhí)行價(jià)格低時(shí)-->higher premium for put price,然后如何可以推出higher implied volatility呢?更高的premium會(huì)導(dǎo)致更高的波動(dòng)率嗎?謝謝老師!
有點(diǎn)忘了, 什么是swap rate?如何應(yīng)用? 在這道題目中,為什么選4.5%/4?
關(guān)于delta of protective put, stock的delta是1,put的delta是【-1,0】,而delta of protective put= d of stock+d of put,所以d of protective put應(yīng)該是【0,1】吧??
