Rhodium is not a precious metal. It's an expensive industrial metal. With the industries that needed it in the toilet, there is something of a surplus.
It's traded in pools by places like Kitco along with gold, silver, platinum and palladium, so it's somewhat considered an investment-grade metal. Or was.
A metal that spiked from under $400 an ounce to over $10,000 an ounce sure got investors' attention there for the time.
