所以,基于这样的权重分配方式,Value-weighted的指数,他的信用风险会更大,更容易受到信用质量较差债券的影响,即,更容易受到债券信用质量质量下降带来的影响。 而相比之下,Equally-weighted给所有的债券权重都一样,受到每一个债券的影响都一样,所以当质量差的那部分债券信用质量下滑时,受到的影响就相对较小。 这个其实...

The following equation for the variance of an equally weighted portfolio illustrates these points:【释义】每个资产的方差(或标准偏差)对投资组合波动性的贡献随着资产数量的增加而减少。
the covariances between the residuals of the regressions of the weighted asset returns with respect to the portfolio return.
