Commodities vs Gold
Each ratio divides one asset's price by another. Dow / Gold is the classic store-of-value gauge; S&P 500 / Gold and Nasdaq 100 / Gold measure financial assets against the monetary metal; Gold / Silver, Copper / Gold and Oil / S&P 500 track cross-commodity and real-vs-financial pressure. An up-sloping ratio means the numerator is gaining on the denominator (gold relatively weak); a down-sloping ratio means the denominator is outperforming.
