Decoy Therapeutics is trading 13.0% lower at $1.54, extending a seven-session slide with no clear company-specific explanation for the October 5 pre-market move.

  • Shares closed at $1.77 on October 2 and have fallen from $3.11 on September 24, with losses in each subsequent session.
  • The latest updates were a September 29 preclinical data release and a September 30 presentation announcement; neither establishes a cause.
  • Major indexes were only slightly lower, so broader-market weakness does not clearly explain the move.
