gdx is not gld

to RockyR

im not smart about GDX, im not sure i can answer your question, so research this idea

but i think that this etf is composed of parts that mine and as such those producers hedge in such a way (straddle is it called ?) that price fluctuations outside of a predicted range, both higher and lower, dampen profits

ie the producers count a a business model where price is stable or slow trend

again im not smart about this and will check it out tonight
