NO.PZ2023032703000044 问题如下 nny Moynahan, CFis a fixeincome portfolio manager ReagInvestment Aisory (Reagan). He agrees with his wife, a professor of investments class, to talk to her class about managing fixeincome portfolios. He plans to put together six pages for his scussion.On page 2, Moynahcis to outline the three totreturn approaches he utilizes to manage Reagan’s fixeincome portfolios. He puts together the following exhibit:How shoulMoynahmost likely label the management approaches for eaof the portfolios scribein Exhibit 1 on page 2 of his presentation? A.Portfolio 1 = Active Management, Portfolio 2 = Pure Inxing, Portfolio 3 = EnhanceInxing B.Portfolio 1 = EnhanceInxing, Portfolio 2 = Pure Inxing, Portfolio 3 = Active Management C.Portfolio 1 = Active Management, Portfolio 2 = EnhanceInxing, Portfolio 3 = Pure Inxing A is correct. Moynahshoullabel the portfolios on page 2 follows: Portfolio 1 = Active Management, whiallows for larger risk factor mismatto the benchmark. Portfolio 2 = Pure Inxing, whiinvolves attempting to replicate a boninx closely possible. Portfolio 3 = EnhanceInxing, whiis closely linketo the benchmark but attempts to generate a most amount of outperformanversus the benchmark. 为什么Portfolio 3 不是pure inx，不是只有3才是完美match了ration吗？而weighting方面2和3又差不多，所以3是pure inx，2是enhanceinxing，为什么是反过来呢？
