NO.PZ2018062002000087 问题如下 For a funmentanalyst who uses publicly available information to temispricing, whis his assumption about the market efficiency? A.The market is weak-form inefficient. B.The market is semi-strong-form efficient. C.The market is semi-strong-form inefficient. C is correct.Accorng to semi-strong-form efficient hypothesis, investors are not able to earn abnormreturns using publicly available information. So the analyst believes ththe market is semi-strong-form inefficient if he uses funmentanalysis.考点Efficient CapitMarket AnIts Forms题干说我们通过市场公开数据可以发现定价错误也就是说基本面分析可以获得超额回报，那么问此时市场属于哪种有效？如果基本面分析可以获得超额回报，那么此时市场肯定不是半强有效的即半强无效。但是半强无效情况，我们就无法判断是弱势有效还是弱势无效。 A是不是funmental， 和technical都有用
NO.PZ2018062002000087 怎么记半强无效？public information不是强有效市场的特征吗？为什么是半强无效？
