问题如下:
Which of the inputs into the portfolio construction process can be measured with certainty:
选项:
A. position alphas.
B. covariance estimates.
C. current portfolio.
D. transaction cost.
解释:
C is correct.
考点:inputs into the portfolio construction process
解析:Current Portfolio是唯一一个可以直接观察到的input,因此是唯一一个certain input。Alphas, Covariance & Transaction Costs 可能有误,不是certain的。因此,选项C正确。
transaction cost也是确定的吧?
