Decoy Therapeutics is trading 9.59% up at $2.97 after no confirmed company-specific catalyst was identified for the September 15, 2026 after-hours move.

  • September 14 shareholder proposals involved warrant issuance and authorized-share changes but were previously disclosed.
  • Broader markets were weaker, so the gain does not clearly track market sentiment.
  • Thin after-hours activity may be amplifying volatility; recheck for delayed filings or announcements.
