I have the figures for the 11 millions US and CDA reported short. With unreported and naked short i understand your 15 M.
Thanks also for the house position. It confirm that Desjardins, MS, TD and Scotia are covering (they are frequently on the buy side).
GS and CIBC are shorting. In CIBC case... they have sold at $ 2.635 and bought at $ 2.651. As for Macquarie, they have sold at $ 2.518 and bought at 2.60... probably the turkey award of the month.
