同學(xué)你好!
這道題還是要回到定義。Active return is defined as the portfolio return minus the benchmark return. Active risk is the annualized standard deviation of active returns。也就是整個(gè)portfolio的active risk。
回到你的問題,這句話的意思還是得看題干。原文是這么說的:The security weightings within sectors can be significantly different from those of the benchmark, but the portfolio’s sector weightings adhere closely to the benchmark weights. 也就是板塊權(quán)重原本偏離基準(zhǔn)不大,個(gè)股很大,因此在滿足constraint的前提下,板塊可以有更大的偏離程度,個(gè)股則更少。這題是這個(gè)意思
