Smith illustrates the returns from this strategy using the swap rate as a proxy for corporate yields. 答案是:The swap spread is a common way to indicate credit spreads in a market. The four-year swap rate ( fixed leg of an interest rate swap ) can be used as an indication of the four-year corporate yield. Riding the yield curve by purchasing a four-year zero-coupon bond with a yield of 4.75% { i.e., 4.05% + 0.70%, [ P4 = 100 / ( 1 + 0.0475 )4 = 83.058 ] } and then selling it when it becomes a two-year zero-coupon bond with a yield of 3.00% { i.e., 2.70% + 0.30%, [ P2 = 100 / ( 1 + 0.0300 )2 = 94.260 ] } produces an annual return of 6.53% : ( 94.260 / 83.058 )0.5 - 1.0 = 0.0653 這里P2 的價(jià)格計(jì)算我不能理解,為什么?我買了4年零息債券,比如到期收到面值100,那么期末100用 swap rate 4 折現(xiàn)到0時(shí)點(diǎn),算出一個(gè)購買價(jià)格。兩年后賣了,那應(yīng)該是先算出 f(2,2) 的 forward rate值,然后第四年的100用 f(2,2) 去折現(xiàn)折到第二年年末,才是這個(gè)債券在第二年年末的賣出價(jià)格。按照答案的意思,算出的是2年零息債券在 0 時(shí)點(diǎn)債券價(jià)格。請(qǐng)問我的理解是否正確? 另,total return 算總的收益,一定要用幾何平均算嗎?

同學(xué)你好,
還是審題的問題,請(qǐng)仔細(xì)閱讀高亮部分文字。
其實(shí)你的答案思路很接近了,有一個(gè)錯(cuò)誤在于,不能用f(2,2)而應(yīng)該用時(shí)間到達(dá)2年時(shí),s(0,2).而題目在高亮部分說明了yield curve 2年以后還是這張表格上面的數(shù)字。
