关于LEVEL1中weak /semi-strong forms的疑惑 technical, profit, returns, morning, afternoon

AnalystAlan

notes中写 weak form无法用technical analysis获得长期abnormal profit/ semi-strong无法用fundamental analysis

但在2013mock morning 88题答案中写的semi-strong form 包含了weak form....= = 一时无法理解 求大神解答

还有,2013mock afternoon中83题 C选项 说semi-strong既不能使technician又不能使fundamental analysts 获得consistently abnormal returns..... =2= 也不太理解哎~

=2= 自顶一下...有大神解答咩？

weak form是current information 充分 semi是historical和current information充分 所以semi比weak多了historical 所以semi 包含weak 技术分析因为近期信息充分所以 没有优势 semi因为historical跟近期数据都充分 所以基本面分析没有优势
我记得是这样 记错了大哥别揍我

weak form - prices reflect all historical information, which means that technical analysis cannot generate abnormal return

semi strong form - prices reflect all public information (past and current), which means technical and fundamental analysis cannot be used to generate abnormal return
