问题如下：
In an efficient market, the change in a company’s share price is most likely the result of:
选项：
A.insiders’ private information.
B.the previous day’s change in stock price.
C.new information coming into the market.
解释：
C is correct.
Today’s price change is independent of the one from yesterday, and in an efficient market, investors will react to new, independent information as it is made public.
这个题目的有效市场没说是哪种有效的市场，强势有效市场中内幕消息也无法影响股价的变化？弱势有效和半强有效内幕交易不是可以影响股价变化？这个题目是考察哪个知识点的？
