Cardio Diagnostics Holdings is trading 6.5% down at $1.45 in pre-market, extending last week’s volatility and sell-off.

  • The move appears to be driven by sentiment and broader market dynamics, as there have been no fresh earnings, SEC filings, or major company-specific headlines to justify the price action.
  • The decline continues a trend observed on July 24, when shares fell approximately 6% in after-hours trading without a clear fundamental catalyst.
