An obvious and better way to make money off gold ETFs and the next gold pop

Please consider the chart of the very popular GLD ETF versus two other gold ETFs, GTU and PHYS.

1 month:

6 month:

If you look closely you can see that the physical-gold backed products have really underperformed GLD. This seems to be because their premium over NAV on the physical funds has evaporated as gold has lost its lustre lately.

The situation will surely be reverted once the next crisis arises. Europe has been quiet for a few weeks. It won't last.

An obvious trade for those who like gold is GTU or PHYS at this point.

Another option is short GLD and go long GTU or PHYS.

As of 3:50PM:

• GLD: $ 130.17 (short)
• GTU:  $49.06 or PHYS $11.53 (long)
