Belden is trading 18.9% up at $131.80 after a sharp after-hours move, with no confirmed September 18 company-specific catalyst identified.
- Belden closed September 18 at $110.89.
- Recent coverage instead references earlier second-quarter results, the completed RUCKUS acquisition, and an insider saleβnot a new late-session announcement.
- Broader indexes were only modestly higher, so the move remains unexplained.
