88 In a highly efficient market, unexpected positive news on a stock is announced to the public. After this announcement, the difference between the market value and the intrinsic value of the stock will most likely:
A remain zero.
B decrease.
C increase.
老师,不是说有效市场中,新信息会使 the market value and the intrinsic value差距稍微变大一些,然后快速变为零的吗?不然的话,也没有套利机会了啊.
