Palladium - ShortCurrently trading at twice-ish of it's production cost. Bubble began due to demand outstripping supply but is being re-propped up by short covering. We're already starting to see it peal off the reestablished highs.

Risk: A deficit still very well exists and can be exacerbated by Russia sanctions on scrap exports.
