Ive discussed this with a coworker what could be at the root of this halt. So there a few signs. 1. A strange 'Alpha'. 2 no order since the opening of the books at 4:00 AM until now. Normally during this time a lot of orders have already been placed, forming the openingtrade. A big sell or buy should not sincerly halt this stock. 3. Teck is presenting its Q2 today. Its a little too much coincidence. I might be wrong but something is fishy here.
