🟢 Tscan Therapeutics is trading 7.8% up in after-hours trading with no clear catalyst identified

Tscan Therapeutics is trading 7.8% higher at $0.19 after-hours; no clear company-specific announcement or reliable report explaining the rise was identified for October 30, 2026.

• The regular session closed at $0.17.
• The latest reported company news was an October 28 collaboration to evaluate automated manufacturing of TSC-101; it does not establish a reason for the move.
• Broader markets were sharply lower, so the after-hours gain diverged from the overall market direction.
