A myth often heard is that precious metal miners offer a good leverage over the price of the metals. With precious metals rising the PM miners see their cash flow multiply at constant mining costs. I'm not digging into why this isn't always the case, I just show some evidence rising when comparing the HUI index to Gold.

We saw excellent gold rallies over the past six months with gold strengthening by $200/Oz between mid July and end December. Gold mining earnings being leveraged to the price level of their output, you could expect a stellar performance of the HUI, with an increase of the HUI:Gold ratio. In the midst of the rallies this indeed worked out.
However, over the short term (graph over a 6 months lapse, daily observations) you'll notice the HUI turning weaker relative to gold during any correction, amplifying the decline of Gold. There is some support at the 0.37 level. We're still above that one. The HUI/Gold ratio dropped below its 50 days moving average (dma). It's about to drop below the 200 dma if weakness continues today. We find pull backs towards a support for the HUI:Gold ratio, despite stronger gold prices. (top graph)
