Donald Marleau says President Trump's increased tariffs on steel and aluminum will give more power to U.S. steelmakers but notes they will likely pass prices onto consumers. He points to historical stock prices and credit quality trends for steelmakers to show how companies like Cleveland-Cliffs (CLF) and Steel Dynamics (STLD) will likely handle tariff volatility. Aluminum isn't created equal, says Donald, as he discusses ways those tariffs will affect it differently from steel.
