按道理说b分别到期,应该比c的reinvestment risk高啊

嗨,从没放弃的小努力你好:
三个Portfolio在Macaulay duration一致的情况下,Reinvestment risk的排序是:
Barbell > Laddered > Bullet
这点是一定成立的,可以当成结论。
Macaulay duration一致,说明平均而言,三个组合现金流发生的平均时间一致。
对于Barbell组合,因为Barbell会有很高的权重在长期,这会拖延组合现金流的到账时间,也就是会增加组合的Macaulay duration数据,为了让他这个组合的Macaulay duration和Bullet/Laddered一致,我们还需要买很高权重的短期债券,这样才会使得平均数Macaulay duration变小。
所以和Bullet/Laddered相比,Barbell组合有很高的权重在短期,例如,在本题中的Portfolio C,买了11.5年的长期债券,为了让组合的Macaulay duration等于5.36年,我们就要买很高的权重在1.5年期,这样才能拉低组合的Macaulay duration、使得Mac.Duration等于Bullet/Laddered组合。
这样对于Barbell组合,我们早早的就会收到大笔现金流,绝对金额很大,且早早就面临再投资的风险。
相比较而言,对于Laddered portfolio,比如本题的Portfolio B,现金流分布比较均匀,没有说哪个期限的权重占主导,最早的一笔大额现金流发生在第三年,且因为每个债券的权重相对较小,所以第三年现金流的绝对数额也比不上Portfolio C在1.5年的现金流数额。
所以综合来看,Portfolio C在第1.5年就收到大额现金流,发生时间早、面临的再投资期限较长,Portfolio B相比,在第三年才收到相对大额的现金流,发生的时间相对较晚(面临的再投资期限较短)、且因为权重小,绝对数额上比不上Portfolio C早期现金流,所以他的再投资风险相对更小。
-------------------------------加油吧,让我们一起遇见更好的自己!

NO.PZ2019103001000016 讲义里说versification会带来Cash flow RI risk.

Barbell portfolios, suPortfolio have maturities only the short-term anlong-term en anthus are muless sirable for liquity management. Barbell的convexité比較大,不是可以帶來漲多跌少的好處嗎?c是不是也對呢?
