Which of the following statements regarding the use of traditional performance measures is an indication of superior risk-adjusted portfolio returns?

A:  a sharpe ratio that is greater than zero
B:  an information ratio that is greater than zero
C:  a sharpe ratio that is statistically significantly different from zero
D:  a jensen's alpha that is statistically significantly different from zero



答案选D。但我觉得statistically significantly different from zero并不能说明jensen's alpha 就是positive。如果是负数，则不能显示出存在superior risk-adjusted portfolio returns。




另外再请教高手parametric noets和indemnified bonds的区别。

望好心人解答。谢谢
