PMs may look frothy, but they are the only vehicle (percieved) for wealth preservation. Fiat currencies or stocks and bonds have people bailing fast. I expect PMs to climb a wall of worry. And when they periodically dump, you can expect the talking heads to always mention "bubble, top, crash, etc".
They are paid by the big boys who know the retail guy will freak out at the big move and panic sell. The selloffs last about 3 days because that's about how long it takes to liquidate the physical stuff and in some other accounts. Big boys buy it up and stair step it higher.
The tulip bubble was silly. PMs have value. Funny. I remember about 13 years ago, I said PMs weren't worth anything. But, paper money is worth even less.
