Lol this is ridiculous. GM decides of the price of aluminum when they buy to build trucks. Traders simply ride waves they can't control.
GM does not set the price of aluminum; instead, it is influenced by market conditions and tariffs. The company has to manage rising costs due to tariffs on imported aluminum, which can affect vehicle pricing.
