同學(xué)你好,干脆咱們重新把這道題梳理一下吧(#^.^#)
A.Principal mapping considers coupon and principal payments.本金映射只考慮了本金,并沒(méi)有考慮到利息,所以這個(gè)說(shuō)法不對(duì)
B. Duration mapping does not consider intermediate cash flows and the portfolio VaR using such method is less than the portfolio VaR using principal mapping.
這個(gè)選項(xiàng)可以這么理解,這里的久期映射指的是把所有的現(xiàn)金流綜合在一起考慮的,用一個(gè)維度,即久期來(lái)反映。站在久期已經(jīng)算好的前提下的話,其實(shí)這個(gè)時(shí)候我們單純的用債券的久期乘以對(duì)應(yīng)利率的VaR值,就能得到債券本身的VaR值了,這個(gè)算出來(lái)的VaR值肯定是小于本金映射算出來(lái)的VaR值的
C. Cash-flow mapping considers the timing of the redemption cash flow payments only,
redemption cash flow payments 指的是本金的回流,cash flow是本金和利息都會(huì)考慮的,這個(gè)也不對(duì)
D. Cash-flow mapping considers the present values of cash flows grouped into maturity buckets, and the undiversified portfolio VaR using cash-flow mapping is greater than the portfolio VaR using principal mapping.
現(xiàn)金流映射算出來(lái)的VaR值是比較小的,要小于本金映射的VaR值,所以這個(gè)說(shuō)法不對(duì)。
