Cardio Diagnostics Holdings is trading at $1.90, up 6.15%, with no confirmed company-specific catalyst for its October 13 pre-market rise.

  • Shares rebounded from the October 12 close of $1.78.
  • Healthcare gained 1.58% pre-market, offering sector context but not confirming the cause of the move.
  • An overnight report covered director Peter K. Fung’s Form 4 for September 30; it does not establish the filing as a reason for the rise. Premarket trading is volatile.
