The day before
On October 7, BIAF was quiet. It traded between $5.87 and $6.29 on 42,407 shares and closed at $6.16. That is a tiny float (1.16 million shares) on very low volume.
Pre-market: the headline at 8:00
The first trades on the 8th were at $6.06 at 4:42 a.m., below the $6.16 close. For more than three hours it barely traded.
At 8:00 a.m. this headline came out: “bioAffinity Technologies Announces Notification of Japanese Patent Allowance Covering Noninvasive CyPath® Lung and AI-Built Algorithm”. The 8:00 bar opened at $6.15.
It ran to $7.65 at 8:06 a.m. Then it kept going: $8.20 at 8:10 a.m. By 8:14 a.m., more shares had traded than exist in the whole float (1.16 million).
The pre-market high was $8.34 at 8:14 a.m. It reversed hard. By 8:18 a.m. it was at $6.50, down 22% from the high. At 8:30 a.m. the company filed an 8-K (a current report). From 8:30 until the open the price drifted between about $6.16 and $6.98. 2.41 million shares traded before the bell, about twice the float.
The wall at $8.00
It opened at $6.38, up 4% from the previous close. By 9:44 it was at $7.54, up 18% from the open. It pulled back to $6.82 at 9:50 and then turned up again.
At 9:54 a.m. someone started offering stock at exactly $8.00, just under the $8.34 pre-market high. The 9:54 minute traded 180,015 shares, the biggest volume since the open to that point.
Stop It's 10:01. BIAF is at $7.62. A large block of shares has been offered at exactly $8.00 since 9:54, and the pre-market high is $8.34. Would you buy here?

The wall peaked at 41,587 shares at 10:01:33, about 4% of the float. At 10:01:35 the first trade printed at $8.00. In about a tenth of a second, 39,716 shares traded at exactly $8.00 and the wall was gone. It wasn't pulled. Buyers ate it. One buy order swept 27,636 shares from $8.00 to $8.19 across 20 price levels.
The 10:01 minute went to $8.36, over the pre-market high. It kept climbing. A buy sweep of 18,437 shares ran from $8.98 to $9.13 at 10:08:07, and the high so far was $9.37 at 10:08. That minute traded 320,143 shares. Within five minutes it was back down to $8.13.
A lower high, and more stock stacked above
It bounced again. At 10:18 it pushed to $8.95, a lower high under the $9.37 top. After that it did not trade above $8.95 before the 12:07 halt.
Meanwhile more stock was stacked above. An ask wall at $9.00 showed up at 10:14. Another at $10.35 appeared at 10:17 and was pulled at 11:57. A wall of 50,157 shares at $9.49 appeared at 11:57 and was pulled at 12:07.
The slide came in steps. At 10:39 a sell order swept 19,157 shares from $8.01 to $7.80 and the minute hit $7.62. At 11:14 another sell sweep took 24,188 shares from $8.01 to $7.87. By midday it was back near $8.00.
One halt at $7.09
At 12:07:00 a sell order swept 62,872 shares from $8.13 to $7.47 across 61 price levels. A second one took 18,998 shares from $7.27 to $7.09. At 12:07:15 p.m. the stock was halted (a volatility pause) with the last trade at $7.09. The same minute, a headline came out: “bioAffinity Technologies, Inc. Announces Approximately $4 Million Registered Direct Financing of Common Stock and Concurrent Private Placement Priced At-The-Market Under Nasdaq Rules”.
An ask wall at $7.09, the halt price, was first seen at 12:07:03. It peaked at 169,237 shares, 14.6% of the float, at 12:07:15 and was pulled at 12:15:44. A 48,000-share wall showed at $7.39 at 12:15.
Stop It's 12:17. BIAF has been halted for ten minutes since its last trade at $7.09, and the financing headline came out as the halt began. Trading is about to reopen. Would you buy the reopen?

It reopened at 12:17:15 at $6.30, 11% below where it stopped. The opening print was one trade of 53,649 shares on Nasdaq. The 12:17 minute ranged from $6.04 to $6.93 and traded 271,702 shares.
The rest of the day
It sank to $5.66 at 12:30, bounced to $6.82 at 1:09 p.m., and at 1:30 a second press release about the financing went out. The afternoon was quiet and drifting, with $5.50 the low after the open, at 3:08 p.m.
It closed at $5.65, below the $6.16 previous close and 40% under the $9.37 high.
In the regular session, 9.86 million shares traded. Counting pre-market and after hours, 12.35 million shares traded: the float changed hands about 11 times, at about 14 times its normal volume.
What to take from it
- A wall just under the pre-market high can break in a blink. Here 39,716 shares at $8.00 traded in about a tenth of a second, and the stock ran another $1.37 in seven minutes.
- A halt can reopen lower than it stopped. The stock stopped at $7.09 and reopened at $6.30. A market buy at the reopen cost $361 more than the screen showed.
- After the top, the next push stopped lower. $9.37 at 10:08, then $8.95 at 10:18. The stock closed at $5.65, below the previous close.

How it traded
Intraday run. It opened up 3.6% at 6.38, then ran from the open to the high of 9.37 in 38 minutes.
| Time (ET) | What happened | Watch it |
|---|---|---|
| 8:00 a.m. | News (Business Wire): bioAffinity Technologies Announces Notification of Japanese Patent Allowance Covering Noninvasive CyPath® Lung and AI-Built Algorithm | |
| 8:06 a.m. | First trade 20% above the previous close of 6.16 | |
| 8:14 a.m. | Pre-market high, 8.34 | |
| 8:14 a.m. | Volume since 4:00 a.m. passes the whole float, 1.16 million shares | |
| 9:30 a.m. | The open: 6.38, up 3.6% from the previous close | |
| 10:08 a.m. | High of the day to the close, 9.37 | |
| 12:07 p.m. | Halted: LULD pause (limit up-limit down). Trading resumes at 12:17 p.m. | |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 5.65, 39.7% below the high |
The shape is a fixed rule, not a judgement: gapped 10% or more at the open, ran 10% or more from the open to the high, and faded if it gave back 30% or more of that move by the close.
