Steve St. Angelo wrote an insightful article relating the silver to gold ratio to the S&P 500 Index. I encourage you to read his articles and analysis.
My commentary on the silver to gold ratio:
The following graph shows the SI/GC ratio versus the S&P500 index beginning in August 1971 when President Nixon severed the final gold backing of the US dollar. Currency in circulation, debt, consumer cost of living, and most prices including gold, silver, crude oil, and the S&P rose in devalued dollar units.
