Cardio Diagnostics Holdings is trading 6.15% higher at $2.07 in pre-market, with no clearly reported company-specific catalyst for September 24, 2026. - The latest identifiable announcement was shareholder approval of director elections and financing flexibility on September 18, reported September 22–23; available coverage does not directly link it to the pre-market move. - Broader markets are lower, making a global-market explanation unlikely.
