jamiejamie semi-strong and strong both encompass the weak form, therefore logically it must hold that all forms will be violated if this opportunity would arise, therefore it's A.
Gina isn't this a violation of semistrong-form efficiency? - intraday effect.
B?
morpheus918 Yes, it violates all 3.
mtcfa If it violates weak form, it violates the others as well.
stevelaz It violates all 3 forms
Gooner7 Should we make the assumption that if it violates the weak form than it violates all 3? That makes sense to me intuitively; kind of like m1,m2,m3
