THE SESSION

  • 09:30 ETOpened at $8.99, -26.7% on the previous close of $12.26
  • 09:30 ETRegular-session high, $9.35
  • 09:31 ETHalted (LUDP); resumed 09:36 ET, after 5 minutes
  • 09:49 ETRegular-session low, $6.85

  • Volume: 23.7M shares in regular hours, 247K before the open

AVTX opened at $8.99 after a sharp premarket decline from the previous close and briefly reached $9.35, but fell to $6.85 by 09:49 ET. TapeRank recorded the stock as an unexplained move, with no filings or headlines within 24 hours, as it ranked as high as #1 before a five-minute LUDP halt at 09:31 ET; the halt did not prevent the early reversal from leaving shares at $7.49 by the regular-session close. The stock finished 38.9% below the previous close on 23.7M regular-hours shares, and a separate halt after the regular session was recorded last.
