AI's New Problem Isn't Demand — It's Margins: Applied Materials Falls 5% on Record Revenue

Cisco beat and dropped 8.4% for the same reason the night before — while Micron, which sells the memory driving those costs, jumped over 4%. The AI trade isn't breaking. The margin is just moving down the supply chain.
