driven by the differences between the security weights in the portfolio and the security weights in the benchmark这句话描述的是active risk还是active share ?

同学,下午好。
这里描述的应该是主动份额。
因为主动份额就是组合和基准的证券权重差额,无论是证券不匹配还是证券匹配、权重不匹配,本质都是组合和基准的证券权重不匹配。

老师请详见往年真题2018年Equity的D问答案,是不是答案有问题?说这句话描述的是active risk

同学,下午好。
这里描述的是主动风险的两个组成部分,因子权重的匹配不同和特殊风险。2019年之后的权益是改写了,应该是前后说法有些区别。

同学,早上好。
原版书原文,参考如下:
Active risk The annualized standard deviation of active returns, also referred to as tracking error (also sometimes called tracking risk).
Active share A measure, ranging from 0% to 100%, of how similar a portfolio is to its benchmark. The measure is based on the differences in a portfolio’s holdings and weights relative to its benchmark’s holdings and their weights.
