The first trades on the 1st were at $4.10, below the $4.56 previous close.

At 8:00 a.m. Business Wire ran this headline: “bioAffinity Technologies Advances CyPath® Lung for Surveillance of Lung Cancer Survivors”. The 8:00 minute opened at $4.62 and closed at $5.09. Two minutes later it touched $8.00.

By 8:02 a.m., more shares had traded than exist in the whole float (584,227). The pre-market high was $8.43 at 8:03 a.m.

The pre-market was a wide swing, not a straight line. From $6.95 at 8:10 a.m. it ran to $8.40 at 8:15 a.m., up 21%. Then it fell to $6.03 at 8:40 a.m., down 28% from $8.40. By 8:46 a.m. the volume was ten times the float. 8.62 million shares traded before the bell.

The open and the push back above $8

It opened at $7.73, up 70% from the previous close. At 9:31 a.m. it pushed to $8.33, up 8% from the open, then pulled back.

At 9:33 a.m. it dipped to $7.06. From there it climbed again. At 9:36:00 one buy order of 54,617 shares swept up through 27 price levels, from $7.88 to $8.14. By the end of the 9:36 minute it was at $8.28.

Here's what happened. At 9:38 a.m. it hit $8.60, the high so far. At 9:38:03 one buy order of 36,170 shares swept from $8.38 to $8.60 across 23 levels. Eight seconds later, at 9:38:11, a sell order of 53,311 shares went through from $8.18 to $7.89. The 9:38 minute fell as low as $7.11 and closed at $7.36.

The halt

At 9:40 a.m. it was halted (a volatility pause). The last trade was at $7.11.

It reopened at 9:45 a.m. at $7.02. The first trade after the reopen was a single print of 55,169 shares at $7.02. The 9:45 minute went up to $7.39. It didn't hold. At 9:48 a.m. it fell to $6.70, down 22% from $8.60.

A lower high at $7.57

It came back once more. At 10:01 a.m. it pushed to $7.57, a lower high under the $8.60 top. The same minute it dropped to $6.58, and the next minute to $6.51.

After that it drifted. The low after the open was $6.13 at 11:03 a.m.

The bid at $6.00

From 1:18 p.m. on, a large bid sat at exactly $6.00, below a stock trading near $6.60. The bid peaked at 55,643 shares at 1:18 p.m., about 9.5% of the float.

At 2:30:27 p.m. it was pulled: the size left the book without trading there.

The close and after hours

It closed at $6.51, 24% under the $8.60 high of the day. 10.57 million shares traded in the regular session, about 18 times the float. With the pre-market included, the total through the close was 19.19 million.

At 4:30 p.m. the company filed an 8-K (a current report). The 4:32 p.m. minute reached $7.50. After hours it reached $8.15 at 5:24 p.m.

What to take from it

• After the top, the next push stopped lower. $8.60 at 9:38 a.m., then $7.57 at 10:01 a.m.
• Big moves came right after both the headline and the filing. It went from $4.62 at 8:00 a.m. to $8.00 by 8:02 a.m. after the 8:00 a.m. headline, and reached $7.50 at 4:32 p.m., two minutes after the 4:30 p.m. 8-K.
• Much of the run was given back by the close. It closed at $6.51, 24% below the $8.60 high, but still above the $4.56 previous close.
