This story is interesting. The price of platinum is now more than the price of gold, per ounce. For a long time, platinum was much more expensive than gold. Recently, gold was more expensive than platinum.
Platinum/gold or gold/silver have much lower volatility than gold/FRN or the stock market. Metals are real money, and prices are mostly stable.
If you look at a 10 year chart of gold/silver/copper/platinum/palladium, they line up pretty closely. If you add the stock market to the same chart, you’ll see why stocks are a worse investment than metals.
