In this case the bushes are the GLD and SLV ETFs, which are getting shaken today to try and shake loose some physical bullion for the hard up COMEX pit crawlers.
So today we are seeing a bear raid in the metals that started last night.
Perhaps this price drop will allow JPM to squeeze some additional bullion out of GLD, which they can add to their stash.
