Boeing faced a punishing session, with shares suffering their sharpest decline since 2020.

Conversely, the construction supply market hit a snag as Armstrong World Industries stumbled. The company missed third-quarter earnings targets and lowered its 2026 profit guidance, signaling potential headwinds for building material suppliers in the coming months.
