Palladium was up 55% in 2017 – the best performing commodity in the world – and if the first two days of this year are anything to go by, 2018 will see a repeat.
Palladium inventories in warehouses tracked by Nymex shrank 25 percent in December, capping a fourth straight annual decline, the longest streak since 2000.

My comment: What happens to the price of palladium when vehicle sales decline? Price could be close to a high.
