同學你好
沒有external dispersion
這個錯是因為他的internal dispersion展示的是錯的。這部分的要求如下
Internal dispersion:a measure of the spread of the annual returns of individual portfolios within a composite. It allows clients to see how consistently the firm implemented its strategy across individual portfolios:衡量單一投資組合與組合組的年化收益的差值,它允許客戶了解公司單一投資組合中如何貫徹其策略(internal risk,站在portfolio角度)
1)Highest and lowest returns earned by portfolios that were in the composite for the full year:組合組中將投資組合全年的收益率最高的和最低的相減(優(yōu)點:簡單;缺點:易受outlier影響)
2)High/low range:最高的收益除以最低的收益(優(yōu)點:簡單;缺點:易受outlier影響)
3)The equal-weighted standard deviation of returns to portfolios in the composite:組合組中投資組合的等權重的收益率標準差
4)The asset-weighted standard deviation:以資產(chǎn)規(guī)模加權的收益率標準差
5)The interquartile range:1/4分位數(shù)排名減去3/4分位數(shù)排名(優(yōu)點:最不容易受outlier影響)
