2022-02-10 10:50老師好!我在原版書中Reading 11, 讀到Convexity, 看到這段話。 感覺(jué)前后矛盾。原版書第247頁(yè)," If a bond has positive convexity, the expected return of the bond will be higher than the return of an identical-duration, lower-convexity bond if interest rates change. This price behavior is valuable to investors, and therefore, a bond with higher convexity might be expected to have a lower yield to maturity than a similar-duration bond with less convexity." 第1句說(shuō)Higher convexity has higher return; 第2句說(shuō), Higher convexity has lower yield to maturity. Single bond return 不就是yield to maturity 嗎? 謝謝

同學(xué),早上好。
凸性有漲多跌少的好處,但是凸性也會(huì)有成本,如果對(duì)應(yīng)的好處抵減成本反倒是帶來(lái)負(fù)收益的,則會(huì)對(duì)整體投資組合產(chǎn)生負(fù)的影響。例如最簡(jiǎn)單的方法是購(gòu)買更多的債券,增加麥考利久期和凸性,但同時(shí)也會(huì)在虧損的時(shí)候虧更多,盈利的時(shí)候是否能夠覆蓋增加凸性的成本,也是需要權(quán)衡的問(wèn)題。
請(qǐng)【點(diǎn)贊】喲~。相信同學(xué)能夠順利通過(guò)考試,加油~
