| 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 |
| birdperson | @gooner7 -its not an assumption. it is literally the theory itself. |
| khalifa92 | thus market is inefficient |
I passed! I did not get a chance to tell you before the exam - but your site was excellent. I will definitely take it next year for Level II.
