问题如下:
If markets are semi-strong efficient, standard fundamental analysis will yield abnormal trading profits that are:
选项:
A.negative.
B.equal to zero.
C.positive.
解释:
B is correct.
If all public information should already be reflected in the market price, then the abnormal trading profit will be equal to zero when fundamental analysis is used.
