re: RGLD
The drop was precipitated by a recommendation in a gold guru's subscription newsletter service (I believe it was Weiss) to take profits in RGLD "above 24" - after the substantial move from the teens - and move proceeds to GG for better short term prospects.
Selling ensued, quickly followed by short traders who spotted an opportunity. (You may have observed that RGLD is a favorite trading vehicle.)
They broke the chart.
I've found nothing changed fundamentally, and their presentation at a Denver conference Monday was upbeat and, by all appearances, well received.
If short positions were compelled to unwind, the thin float and volume might fuel a volatile reaction...
