问题如下：
Technical analysts assume that markets are:
选项：
A. weak-form efficient.
B. weak-form inefficient.
C. semi-strong-form efficient.
解释：
B is correct.
Technical analysts use past prices and volume to predict future prices, which is inconsistent with the weakest form of market efficiency (i.e., weak-form market efficiency). Weak-form market efficiency states that investors cannot earn abnormal returns by trading on the basis of past trends in price and volume.

这道题难道不是a么？技术分析不就是在weak form的么？
