IGM is trading 3.36% higher at $170.24 after hours, though the move’s cause remains unclear. - IGM’s regular-session close was $164.71; no clear IGM-specific announcement or late-breaking catalyst surfaced in available coverage. - Hotter U.S. inflation and rate-hike concerns weighed on technology and AI-related shares during the session. Reuters also reported that higher-rate fears and AI financing concerns pressured tech stocks, but this does not explain IGM’s after-hours rise.
