Norbord warrants Check out the Norbord warrants at NBD.wt . Today they traded up to as high as 0.88 cents. They expire in December of 2013. I think the way they work is that 10 warrants can be exchanged plus $13.60 for 1 share of NBD. A dollar incease in NBD should be worth 10 cents for the warrant. There could be big potential for the warrants next year if NBD continues its upward trend.
