The gold silver ratio (AU/AG) has been in a decline. At the end of the current decline an upward sloping flag formation is in place. According to those who understand these patterns this indicates there will be a breakout to the downside of the AU/AG ratio, meaning that silver should be expected to do better than gold when there is a breakout.

This doesn’t mean necessarily that silver will gain in value when pegged to the dollar. Silver can still decline while gold will decline more. Or it could mean that gold will gain but silver will gain more. Many editorials on this subject expect a gain in the dollar, which indicates a decline in gold. Pick your poison.
