Regarding the currency overlay program, it will add value to the portfolio only if the currency alpha has a low correlation with other asset classes in the portfolio 為什么？
解析是什么意思？ The high correlation between the currencies does not help here because the investor will be using forward contracts to sell both of these currencies. ？？
題目不是說了the shares had increased to EUR100 each 并且 and the increase in the notional size of the position was hedged using currency options。這么重要的信息為什么不用？
a decline in the US trade deficit, 說的很模糊啊，絕對(duì)值的減少還是帶符號(hào)的減少？
B選項(xiàng)不重要么，為什么？
題目哪里說了這是Exchange-traded futures
1.投資外幣無風(fēng)險(xiǎn)資產(chǎn)標(biāo)準(zhǔn)差為什么不是前面方差的根號(hào)，F(xiàn)X的項(xiàng)均為0？得出DC標(biāo)準(zhǔn)差等于FX標(biāo)準(zhǔn)差。 2.推論這里GBP為外幣，個(gè)股企業(yè)是這個(gè)英國個(gè)股，考察的就是外國企業(yè)？
解析這句話怎么理解，An increase in the expected correlation between movements in the foreign-currency asset returns and movements in the spot exchange rates from 0.50 to 0.80 would increase the domestic-currency return risk but would not change the level of expected domestic-currency return. 這是為什么？
請(qǐng)解釋下這題三個(gè)選項(xiàng)，完全不知所云
什么是effective interest rate? 不應(yīng)該是凈的概念嗎
老師，幫忙解釋下這道題為什么選A呢
老師，這道題是沒講清楚嗎，只給了10-year CDS的notional，和勇long-short CDS strategy就能說明期初要構(gòu)建的組合是interest rate netural的嗎？另外long哪個(gè)，short哪個(gè)也沒說
老師，這道題的解題思路是什么
老師，difference1說的是什么意思？difference2和3為什么不對(duì)呢
老師，對(duì)嗎？
