问题如下:
Which factor is inversely related to optimal corridor width?
选项:
A.Factor 1 B.Factor 2 C.Factor 3解释:
Volatility of the rest of the portfolio is inversely related to optimal corridor width. The higher the volatility, the narrower is the optimal corridor. Higher volatility makes large divergences from the strategic asset allocation more likely.
Transaction costs and correlation with the rest of the portfolio are both positively related to optimal corridor width.
Factor 3: Volatility with the rest of the portfolio,组合内其他部分资产的波动越大,相对而言考察资产本身波动越小,考察资产的rebalancing corridor越小,所以是inversely,是这样理解吗?例如:组合内AB两个资产,B的波动大,相对A的波动小,A的rebalancing corridor小,所以B的波动与A的rebalancing corridor反向
