🔴 Illumina is trading 16.21% down in after-hours trading — no clear catalyst

Illumina is trading at $224.49, down 16.21%, after the regular-session close at $267.93; the cause of the sharp after-hours drop remains unclear.

• No verified company announcement or late-breaking catalyst explains the move.
• Illumina announced its BioInsight software platform on October 14; the FDA recall listing concerns a previously communicated correction, not a newly identified disruption.
• Hotter inflation and rate concerns pressured technology shares, but available market information does not establish broader sentiment as the cause.
