But, since the demand now is getting much and there are lots of companies now jumping on the production of EV, then you should also see the value increase as well to match the level of demand that there is. That is just the case here, and it would still go further.
So, oil companies went from "we need to halt all oil production because it worths nothing now!" to "we need to find more oil!!" in a single year, and that resulted with lack of oil, and obviously the price skyrocketed. Eventually the production and the demand will see eye to eye and that is when everything will be normally priced again, will take a while but it will surely happen.
