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？
