选项:

A.

highly efficient market.

B.

low opportunity cost of not hiring a skilled manager.

C.

high opportunity cost of not hiring a skilled manager.

解释:

C is correct.

When the two distributions are highly distinct, the unskilled managers are expected to significantly underperform the skilled managers, implying a high opportunity cost of not hiring the skilled managers. Efficient markets are likely to exhibit smaller differences of returns between skilled and unskilled managers.

嗨,从没放弃的小努力你好:
