选项
A.5.1%.
B.5.3%.
C.6.3%.
答案
C
解析
： C is correct. The portfolio return must be calculated as the weighted mean return, where the weights are the allocations in each asset class: (0.20 × 8%) ＋ (0.40 × 12%) ＋【0.25×(-3%)】＋ (0.15 × 4%) = 6.25%, or ≈ 6.3%. 去年，一位投资者将他的退休储蓄分配到如下表所示的资产类别中。问2015年的投资组合收益率最接近多少。 C正确。 投资组合的回报须以加权平均回报计算，其中的权重是每种资产类别的配置: (0.20×8%)＋(0.40×12%)＋【0.25×(-3%)】＋(0.15×4%)= 6.25%或≈6.3%。
