Honeywell International is trading 16.38% up at $235.50 after no reliable September 11, 2026 company-specific catalyst was identified.
- Latest available company updates point to a September 3 investor-conference announcement and a September 15 earnings event, rather than a post-close release.
- The broader market was positive on September 11 but does not explain the unusually large after-hours move; treat the rally cautiously pending confirmation from company filings or additional reporting.
