Q5,C選項(xiàng)delta也是=0的吧?C為什么不對呢? 視頻講解老師突然得出應(yīng)該用risk reversal策略,沒懂怎么得出來的
百題Case 12——Jan Magnuson 在哪里聽這個(gè)視頻?謝謝
請問-20bps是什么意思?為什么變成EUR+70bps-(EUR-20bps).不明白這個(gè)合成是怎么構(gòu)建的。請老師詳細(xì)分析一下,謝謝。
Generally speaking, implied volatility increases for put options at strike prices that are lower than the current stock price, whereas implied volatilities decrease for call options for strike prices that are higher than the current stock price; this is called the volatility skew. However, sometimes implied volatility decreases for put options at strike prices that are lower than the current stock price, whereas implied volatilities increase for call options at strike prices that are higher than the current stock price; this is called the volatility smile.
老師。B選項(xiàng)我不明白為啥遠(yuǎn)期溢價(jià)會(huì)有利。遠(yuǎn)期溢價(jià),USD漲。借入U(xiǎn)SD,為啥會(huì)有利
百題 case Albert Wulf第3問,為什么是short OTM put呢?題目不是要求完全保護(hù)downside risk嗎?short put不就又打開了下行風(fēng)險(xiǎn)?short call只是限制上行potential而已?
關(guān)于forward rate bias這句話【buying currency trading at forward discount, selling currency trading at forward premium】, 字面意思是投資者應(yīng)該在現(xiàn)貨市場買入遠(yuǎn)期會(huì)折價(jià)的貨幣,在現(xiàn)貨市場賣出遠(yuǎn)期會(huì)溢價(jià)的貨幣。我的理解是當(dāng)forward rate小于spot rate(forward discount),從carry trade角度很好理解,就是投資者投資high-yield currency,以獲得更高的收益率;但是從forward rate bias角度,就是投資者在現(xiàn)貨市場買入base currency,將來再以遠(yuǎn)期折價(jià)賣掉,這個(gè)不是會(huì)產(chǎn)生虧損的事情嗎?從文字解釋上面我不是很理解forward rate bias這句話,麻煩老師解釋一下
overlay manager是啥意思
1. Q4, statement 1中direct one-for one hedge ratio是怎么hedge的呢? 2. MVH中的Y是R(Dc),X是R(FX)是嗎?還是根據(jù)情況,x和y所指的內(nèi)容會(huì)變化。 3. 沖刺筆記里Joint optimization中說的改進(jìn)方法,可以列式講解一下嗎? 4. 傳統(tǒng)的MVHR是指的銅期貨,銅現(xiàn)貨嗎?或者Y是R(Dc),X是R(FX)?
如果用總收益7%減去純資產(chǎn)部分的加權(quán)收益5.5%,剩下1.5%就是匯率貢獻(xiàn),與答案1.495%對不上呢?
Q3我看了幾個(gè)解答覺得還是不對。lecture里明確的說了,如果long了high interest rate的currency后其繼續(xù)貶值,是有虧損風(fēng)險(xiǎn)的。我們這里的情況應(yīng)該是在借了美元long盧比以后的情況,所以答案應(yīng)該是A啊
老師這個(gè)支付歐元利息應(yīng)該是?50bp吧…70-20…
第三題,SEK不是緊縮的貨幣政策么。那不是會(huì)使得SEK相對EUR升值么,賣EUR的話roll yield 不是應(yīng)該是負(fù)的么?
展期咋是先賣EUR后買EUR?不應(yīng)該先平倉買EUR嗎?展期再講一下不理解
所以roll yield分別是多少啊?數(shù)是多少???
