We have an oversupply of Gold (Mined at a massive rate). Falling demand of Gold. Rising US rates on the horizon. Maybe Jim Rogers was right when he said there would be a bubble of the US Dollar which might cause the gold price to fall at which point he would by gold ($1000 US was what he thought from memory). Long term I think Gold will do well but maybe we will see a sharp downturn soon.
I thought I explained it pretty well. These are the forces building against the gold price for a short term fall. It is already happening. When it ends I will be there to buy.
