Silver started outperforming Gold from August 2010. If the rally never occurred, Gold would have been the leader at 149%. Going forward, the Gold/Silver index should be dropping in the next few years. Many long term Silver holders may start selling some of their positions when the Gold/Silver ratio is under 20. Some have stated that the Gold/Silver ratio may go down to the 10 area or slightly below.
If Gold hits $5000 an ounce, a 15/1 Gold/Silver ratio will put Silver at $333
