The GDX ETF is an ETF based on medium-sized gold miners ("juniors" to the big miners).

It's a good proxy for general sentiment on gold mining + the markets in general.

It was in the process of peaking at the time of the previous KXL NR one month ago, so that punted the KXL SP extra-far.

This time, instead, we have a great NR, but into a bit of a general headwind.  The winds will abate, and gentle pressure under KXL will likely lift it, if there are no subprime big problems.
