如果無風(fēng)險(xiǎn)資產(chǎn)和資產(chǎn)組合的相關(guān)系數(shù)為零，那么兩者之間的有效前沿不應(yīng)是曲線嗎？為何是連線？

Wallace, an emerging market bond trader, is holding a 5-year USD Malaysian corporate bond in his book. He is concerned about the risk of his position. Which of the following statements concerning the risk of his position is incorrect? A The corporate bond could be upgraded so that it would have a higher rating than Malaysian sovereign debt, but it is highly unlikely. B Buying protection with a CDS would hedge the corporate bond position against some risks but it would do a poor job of hedging the position if there is a drop in liquidity for emerging market sovereign bonds. C A short position in Ringgits sovereign bond from Malaysia would always help hedge the corporate bond against currency risk if the corporation is an exporter. D A short position in a 5-year US treasury and buying protection on the corporate bond using a CDS would be a better hedge than just buying protection on the corporate bond. 麻煩解釋一下c
