借这题，想区分下portfolio rebalance 和 portfolio completion之间的区别，讲义中对于portfolio rebalance的描述是"maintain exposure to target weight", 而对于portfolio completion的描述是"fill gaps in strategic exposure", 而题干中既提到了"gaps","maintain benchmark exposure","changes in sector weightings"； 好像和portfolio rebalance中要保持不偏离target weight也很符合。
