Most of HAR's profit comes from digging gold out of the ground, processing it, and selling it to the world market. So when the gold price goes up, more of what they pull out is worth money, and the share tends to rise with it. That's why you see gold miners move so much when the gold price shifts, more than a bank or retail company would.
