Only from the point of view of the association between Lithium for batteries etc & the rare earths in particular Neodymium (Nd) which is up to 500% stronger than a comparable ferrite magnet allowing for both weight & physical size reductions thus creating electric motors stronger, smaller & lighter, all the major ingredients for ALL electric motors but in particular those for motor vehicles.
Naturally all investors should decide for themselves & be comfortable in their decisions & holdings however with some countries & cities now legislating to become internal combustion engine free within the next decade which is only going to expand a decision to get involved with rare earths especially Nd in the earlier stages SHOULD prove to be very beneficial.
Of course there is NO guarantee particularly with all the hassles going on in the world but unless there is a major catastrophe globally the marriage of Lithium with Neodymium in an investment portfolio makes good sense.
Best of luck, cheers
