achu I is test for weak EMH.
III is indeed for semi-strong.
Now, II: would that be a test for the weak EMH?
danrow I think (II) is a test of strong EMH.
todolist (II) is a test of strong EMH - nobody beats the market!
steved333 yep. strong.
johntan1979 II is not strong form. II is not even a relevant test of EMH, since it only states "performance", which can be outperform or underperform the index. Only if stated "underperform the index", this supports semi-strong form.
Shaan23 Yeah John is correct.

That is not a test for any of the EMH's.
