这几个指标能详细说一下吗、谢谢！如果我想直接听一下这个经典题目的视频，应该如何去查找？

NO.PZ2023010903000064 问题如下 For eafun risk targets have been assignethallow the portfolio managers some flexibility to exercise their perceiveskillsets. Skills inclu stopicking, factor exposure, ansector rotation. Baseon only the ta shown in Exhibit 2, Langhintifies the skill applieeamanager.Among the fun shown in Exhibit 2, whione is most likely manageusing a versifiemulti-factor investor approach? FunX FunY FunZ The risk targets for FunZ are most likely those of a manager using a versifiemulti-factor approach. Low single-security risk of 1% anmost overall portfolio risk of 4%, combinewith flexibility on sector risk, monstrate a highly versifieportfolio thprimarily emphasizes factor exposures. FunX hrisk targets consistent with emphasis on stopicking—namely, high active risk, high exposure to risk from a single security, anlow sector viations. FunY hrisk targets consistent with emphasis on sector rotation—namely, high active risk ana high toleranfor sector viations.A is incorrect. FunX hrisk targets consistent with emphasis on stopicking— namely, high active risk, high exposure to risk from a single security, anlow sector viations.B is incorrect. FunY hrisk targets consistent with emphasis on sector rotation—namely, high active risk ana high toleranfor sector viations. 老师，在别的答案中看到“sector rotator”这个策略，但是讲义图上没有，可以大体讲一下特征吗？以及如果在图上它的位置？
