同學(xué),下午好。contribution是貢獻(xiàn),計(jì)算的是外匯收益這部分的貢獻(xiàn),是比重×相應(yīng)的收益率。
圖二問號(hào)那里,其實(shí)是total return展開式中的一部分。
在計(jì)算total return時(shí),用公式:weight*(1+RFC)*(1+RFX)求和再減1。weight*(1+R FC)*(1+RFX)求和再減1,就是以下三部分的和(如果把計(jì)算公式展開的話):
The weighted asset return is equal to 5.5%, calculated as follows:
(0.50 × 10.0%) + (0.25 × 5.0%) + [0.25 × (–3.0%)] = 5.5%.
The weighted currency return is equal to 1.5% calculated as follows:
(0.50 × 0.0%) + (0.25 × 2.0%) + (0.25 × 4.0%) = 1.5%.(這部分是純外匯)
The weighted cross-productis equal to –0.005%, calculated as follows:
[0.50 × (10.0% × 0.0%)] + [0.25 × (5.0% × 2.0%)] + [0.25 × (–3.0% × 4.0%)] = –0.005%.(這部分是外匯和asset的交叉項(xiàng))
所以外匯的貢獻(xiàn)是1.5%+-0.005%=1.495%≈1.5%。
