NO.PZ2015121801000068 问题如下 analyst hma the following return projections for eaof three possible outcomes with equlikelihooof occurrence:If the analyst constructs two-asset portfolios thare equally weighte whipair of assets provis the least amount of risk rection? A.Asset 1 anAsset 2. B.Asset 1 anAsset 3. C.Asset 2 anAsset 3. is correct.equally weighteportfolio of Asset 1 anAsset 2 hthe highest level of volatility of the three pairs. All three pairs have the same expectereturn; however, the portfolio of Asset 1 anAsset 2 provis the least amount of risk rection. 我用计算器算出来1 2的r=0.5，1 3的r=-0.5，为什么是选择0.5而不是-0.5
