同學(xué),早上好。
這里協(xié)會(huì)是有勘誤的,勘誤內(nèi)容如下:
In the information for Questions 10-15, after “Easton:” (page 300 of print) should read, “If the correlation of the expected defaults on the CDO collateral of the senior and subordinated traches is positive, the relative value of the equity tranche compared with the senior and mezzanine tranches will increase.”
In the solution to Question 15 (page 302 of print), the last sentence should read, “As correlations increase, the values of the equity tranches usually increase relative to the values of the senior and mezzanine tranches.”
其實(shí)這里的邏輯是一樣的,
相關(guān)性增加,代表高級(jí)債違約,次級(jí)債也會(huì)違約;高級(jí)債不違約,次級(jí)債也不會(huì)違約。那我不如買收益更高的次級(jí)債;
相關(guān)性較少,代表高級(jí)債不違約,次級(jí)債會(huì)違約,另一種情況不可能。那我肯定是要買有收益的高級(jí)債,而避免違約的次級(jí)債。
致正在努力的你,望能解答你的疑惑~
