Co-Diagnostics, Inc. is trading 5.5% down at $5.88 in pre-market, extending sharp volatility following an S-3 resale registration filing.

  • Shares have fluctuated significantly since late May after an effective registration for up to 4.94 million shares and warrants triggered heavy selling and a subsequent rebound.
