We can see that Palladium, Rhodium, Platinum are the top 3 earners for ZIM, in that order.
All these charts have been on the decline since early last year, but picking up again recently.
Platinum was slightly down last night (-0.3%)
Palladium was up over 3%.
while Rhodium's last rise was over 10% (yes it's technically very overbought now)
