Are you trading intra-day? The spike was mainly on GLD and not much on GDX or NUGT. For GDX or NUGT the daily move appears to be less than the average trading range. For NUGT the average range for the past four days has been a minimum of 2 points. Today it hasn't even reached 2 points. So the gyrations are less than what would be considered extreme. Unless of course I am misinterpreting.
For those trading intra-day GLD or gold futures, the spike might have caused some panic. It might even have triggered stops of the weak holders across multiple bar intervals. Lets see if this was a shake out and whether price is going to start moving up from here. So far futures and GLD, GLD, NUGT are all stabilizing.
The fact that price hasn't continued down and has maintained it's composure might show underlying strength. Lets see what price decides to do. Price after all is the best arbiter of opinion.

p.s. On second thought, that gold spike was nasty, especially for those holding the futures.
