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,并沒有考慮到利息,所以這個(gè)說法不對(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)算出來的VaR值肯定是小于本金映射算出來的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)金流映射算出來的VaR值是比較小的,要小于本金映射的VaR值,所以這個(gè)說法不對(duì)。
