CF Industries, Nutrien, Mosaic and ICL Group are poor long-term holdings despite surging 10-30% on the Hormuz-driven urea spike. Fertilizer shares Maersk's flaws of cyclicality, weak capital allocation and no economic moat, and amplifies them. Demand follows farmer budgets: when crop prices are high farmers splurge on inputs, and when crops fall they cut back. Urea's 80% jump to $730 a ton reflects a supply shock as Gulf exports are cut off, not a durable advantage. x.comÂ
