解释：
关于total value added 不是应该是2.3+3.9么，为什么选项C说是3+3.9？
本题求得是选股带来的收益3.9， 下一题是资产分配带来的收益2.3
那么选项C中的3是哪里来的呢？
NO.PZ201710100100000501 3.9%. 6.1%. B is correct. Baseon the fferences in returns for the portfolio anbenchmark in Exhibit 1, the value aeeaasset class within the portfolio is shown in the following table: The value aefrom security selection is calculatethe sum of the actuportfolio weights multiplieeasubportfolio’s value aemeasure. Thus, the value aefrom security selection is calculateas: Value aefrom security selection = 0.63(5.3%) + 0.28(0.2%) + 0.09(5.1%) = 3.9%. A is incorrect. It represents the value aefrom asset allocation. C is incorrect. It represents the totvalue ae(3% + 3.9% = 6.1%). 考点composition of Value Ae解析注意题干“value ae... attributable to the security selection”。代入计算公式 Value aefrom security selection = 0.63(5.3%) + 0.28(0.2%) + 0.09(5.1%) = 3.9%。答案中的3%是如何得到的？
表1最后一列strategic asset allocation是什么意思

strategic asset allocation是benchmark portfolio的weight么？？？这个要怎么分辨？
请问表格里面最后一列，strategic asset allocation是什么意思？没见过这种表达呢？
