RE:COBALT SNAPSHOT: Alloy grade premium emerges after Chinese-Futures for Cobalt are able to trade on CME since mid December 2020. All prices for calls are going up.

Such (future) products are not developed because it is assumed that Co will no longer play a (significant) role in the future. The opposite is much more the case...
