问题 单项选择题

在过去的4年间,基金A、基金B、基金C与市场组合的相关数据如下表所示:

平均收益率(%) 标准差(%) β值
基金A 15 18 1.1
基金B 19 25 2.3
基金C 30 24 0.8
市场组合 12 15 1
期间对应的无风险收益率为5%。
根据上述资料,可以判断下列说法中正确的是______。
(1)如果投资者仅仅投资了基金A,根据夏普比率可知,他的投资绩效弱于市场组合
(2)如果投资者仅仅投资了基金B,根据特雷诺比率可知,他的投资绩效弱于市场组合
(3)如果投资者仅仅投资了基金C,不论考虑夏普比率还是特雷诺,他的投资绩效都强于市场组合
(4)如果从詹森比率的角度进行评估,那么上述3只基金均取得了好于市场组合的投资业绩

A.(1)(2)
B.(2)(3)
C.(3)(4)
D.(4)(1)

答案

参考答案:B

解析: 根据题中给出的相关数据可以得到下表:

平均收益率
(%)
标准差
(%)
β值 夏普比率 特雷诺
比率
詹森比率
(%)
基金A 15 18 1.1 0.56 0.09 2.30
基金B 19 25 2.3 0.56 O.06 -2.10
基金C 30 24 0.8 1.04 O.31 19.40
市场组合 12 15 1 0.47 0.07 0
另外,“当投资人当前的投资组合为唯一投资时,用标准差作为投资组合的风险指标是合适的;当投资人除当前投资组合外,还有其他若干投资组合,即投资完全分散化时,则选择β值作为当前投资组合的风险指标是合适的”。综上所述可知:B选项正确,而A选项、C选项与D选项均错误。
