Trading,冲刺笔记 129页,A good benchmark should not reflect these systematic biases, where the correlation between A and S should not be statistically different from zero。 A,S 相关性系数=0. 这句英文“A and S should not be statistically different from zero”是指相关还是不相关?

同学你好,这句话说的是A和S应该不相关。好的benchmark应该能把active management return和style return 区分开来,因此A和S相关性要很低。
