Unlike the commons the warrants trade more in Canada.  The warrants seem to trade at little or no premium to the commons and when they are sold off as they have been recently the volume dries up considerably.  Also some of the brokers like CIBC and Scotia who normally trade on a daily basis are seeing their warrants taken away by a third party.  If you are in the market for warrants and watch them carefully you can sometimes sneak in and pick up some trading shares while the usual suspects are napping.

Two years ago thanks to Kewl2 I got into the warrants 2014 and they have been really good.
