NO.PZ2016071602000013 问题如下 The pension management analysts Big Inuse a two-step process to manage the assets anrisk in the pension portfolio. First, they use a VAR-baserisk bueting process to termine the asset allocation across four broasset classes. Then, within eaasset class, they set a maximum tracking error allowanfrom a benchmark inx antermine active risk buet to stribute among invimanagers. Assume the returns are all normally stribute From the first step in the process, the following information is available.Whiof the following statements is/are correct?I. Using Vthe risk bueting measure, the emerging markets class hthe smallest risk buet.II. If aitionllwere aeto the portfolio, the marginimpaon portfolio Vwoulgreatest if it were investein small caps.III. the maximum tracking error allowanis lowere the invimanagers have more freem to achieve greater excess returns.IV. Setting well-finerisk limits anclosely monitoring risk levels guarantee thrisk limits will not excee A.I anII only B.I，II，III，anIV C.II anIII I only A is correct. Risk buet is representethe inviVAR, whiis the smallest for emerging markets, so statement I. is correct. The marginVis highest for small caps, so aing one llto thasset class woulhave the largest impaon the portfolio. Statement III. is incorrect, lowering TEV woulgive less, not more freem to manages. Finally, setting risk limits es not ensure they will not excee Bluanexceptions chappen, even if the risk mol is correct. 老师，求问MarginVar和IncrementVar，对Statement II，为什么不是Incrementa，谢谢
