Among precious metals, gold is a safe-haven variety, so the trend is quite special. Silver will follow gold, but it has deviated from 20 12. At present, the hedging properties and commodity properties of precious metals are reflected, and the trend is rather strange. Moreover, after 20 12, silver has quickly become an upset, so the trend is not very active, and it is gradually drifting away from gold. However, it is still quite different from the trend of colored goods, and only maintains the overall consistency of the goods.
