市場係指當地指數,即係大市,大家都會以此作為指標,你講既情況係跑贏大市,但咁唔代表市場冇效.原因係指數功能主要係如實反映市場實況,所以指數選股唔係以回報作為考慮,主要以行業代表性,市值,流通量三個基礎做考慮.
譬如你話大陸市場,我反而認為係更失效,有咩理由一個7.5增長既國家,股市會攪到如此田地?是但一條數講緊大話,唔真實既市場就係失效,係唔會同回報有關,而係同投資者不信任市場有主要關係.

Not correct.
The investor beats the market once does not mean there is a trading rule which can beat the market always.
This is the only case where it breaks the EMH.
