The Gold/Silver Ratio Gold, Silver, and their Relationship

The Gold/Silver Ratio Gold, Silver, and their Relationship; Between 1969 and 1980, the correlation coefficient between the prices of gold and silver was 0.9267. Between 2001 (when silver was at its lowest) and today (2013), the correlation coefficient was 0.8106. Which means that almost 2/3 of the silver price moves in this secular bear
