Food prices are correlated to fertilizer prices, because when food rises (leading indicator), farmers will be able to buy more fertilizer. Then they grow more food and that will push food prices back down.
Buy Verde Agritech to bet on rising fertilizer prices. Trust me.
Of that cathode material cost, lithium is half of that cost. LFP batteries are the cheapest so I expect lithium demand to grow faster as they use more LFP batteries in the future.
Aluminum is expected to go in deficit in the coming years. Since steel is correlated to aluminum, you can also buy steel companies. Hint: ArcelorMittal.
