The Gold-Oil Ratio Revisited
Thanks to a subscriber for this article from Goehring & Rozencwajg which may be of interest. Here is a section:

Oil was lower only 13% of the time (70% less often). On average, oil outperformed gold by 28% during these periods compared with 2% normally.
At the other extreme, when the gold-oil ratio was less than 10:1 (i.e., oil was expensive relative to gold), crude lost 7% on average over the next twelve months and was negative nearly 60% of the time. Gold returned 18% on average during these periods, outperforming oil by 25%. Since 80% of all observations occur when the ratio is between 10 and 30 you should expect the relative returns of both gold and oil to be like their long-run averages and that is exactly what occurred. When the ratio was between 10 and 30, oil returned 5% on average in the following 12 months, and was lower 41% of the time while gold returned 4% and was lower 33% of the time, roughly in line with long-term averages.
We last used this analysis in early 2016 to justify our investments in oil-related securities. At that point, the gold-oil ratio hit a then-record 47:1. We argued that oil prices were set to surge and invested in oil-weighted E&P securities as a result. Over the next 30-months, oil rallied by 191% from $26 per barrel to $76 per barrel by October 2018. Gold on the other hand fell by 4% over the same period. Oil stocks (as measured by the XLE ETF) advanced by 56%, well in excess of gold stocks (as measured by the GDX) which rose only 3% but lagging the S&P 500 which advanced 69%.
