Quote from ARogueTrader:
The gold sector is a very small sector, when you compare it to other sectors like health care, telecom, etc. Someone doesn't have to know something to move gold stocks, they just have to be buying into that sector. Because the gold market is very thin and very speculative, one large buyer into a fund could easily more the entire gold stocks sector.
It doesn't take much for gold stocks to move up or down on speculation.
You still have yet to provide any evidence of direct correlation, you theory may or may not be accurate.
What nitro said is accurate, that unless you are on the inside of a price manipulation scheme it is worthless information for traders and likely a waste of time to even bother with.
What you're saying is true - a single big fund buyer could move the market - but if you check the 5-day charts for any of the big golds you'll see that last night's buying had an urgency to it that can't be reasonably accounted for even by the customary irresponsibility with which fund managers tend to operate.
I can't "prove" my position - but then, who can "prove" anything. Even scientists never consider anything ultimately "proven" - with exceptions in the field of mathematics.
My position is based on probability - the raw material of trading. That surge in the gold sector last night was probably more than coincidence. Whether or not such a consideration is useful for trading gold stocks is a matter of personal judgement.
