There are certain expenses involved in owning zinc, or any other commodity. However, they are not nearly so large as the expenses incurred by a corporation mining zinc (or producing any other commodity) at a loss. Just watch. Even if this trade doesn't work out for you, you will have learned something, and knowledge is worth something. Plus, you might get lucky. I hope so, but if you do, don't let a stroke of luck cloud your vision.
A good bottom's hard to beat.
