Base metals close lower in overnight session; alumina down 2.32%

The breadth of the overnight decline matters more than any single move: losses across copper, aluminum, zinc, nickel and tin point to a broad risk-off tone in industrial metals rather than an isolated story. Alumina's 2.32% drop stands out as the sharpest move and bears watching given its role as an aluminum input, while lead's lone 1.37% gain suggests the selling was not uniform. Whether lead's relative strength persists or the complex continues to move in lockstep is the open question.
