计算factor weighting就用benchmark？

Because of the poor relative performananhigh fees of active management over the past severyears, Camme hbeen fielng increasing number of inquiries from clients about the best ways to use passive solutions for equity exposure. Camme meets with client Sylvia Parker, who seeks guinin establishing passive exposure for her $400 million family fountion. For a portion of equities, Parker wants to use inx approaaugmentefactor-basesolutions. She comments, “I hethfactor-baseapproaches cusewhen pursuing risk-austereturns superior to thof a comparable market cap-weighteinx. In aition,funmentweighting cenhanreturn, but when comparewith intrinsic values, it hthe saantages of overweighting overpricestocks anunrweighting unrpricestocks;value factor fun seek to lower wnsi risk; anrelative to cweighting, single-factor fun tento concentrate risk exposure.”Camme suggests to Parker ththe first priority in moving to a passive solution is to consir the choices available for inx exposure. Owing to the large size of the fun Camme recommen choosing a replication manager in orr to minimize totcosts. He explains the fferences between full replication, stratifiesampling, anoptimization when constructing the portfolio. Parker likes the ia of blenng stratifiesampling with optimization anasks Camme to intify the appropriate manager baseon the ta in Exhibit 1. Exhibit 1 Equity Replication ManagersIn reviewing the relative performanof Manager B from Exhibit 1, Parker makes the following statements:He facemore volatile markets ththe others baseon the tracking errors. He usecurrenoverlays to lever the returns of securities helin foreign currency. His excess return looks like it is more a matter of luthskill. Another client is Ken she, the new chairmof the investment committee of the ventown Arts Enwment. He wants Camme to help him unrstanthe primary investment strategy being followethe MultiFfun whiuses severfactors to structure anmaintain its large-cactive portfolio. The funuses benchmark segments of four mutually exclusive sub-categories shown in Exhibit 2.
