The day before

On September 1, BIAF ran from $4.54 to $8.60, after a low of $4.10. It gave some of it back and closed at $6.59. About 20.8 million shares traded that day.

At 8:00 a.m. on the 1st, Business Wire ran: “bioAffinity Technologies Advances CyPath® Lung for Surveillance of Lung Cancer Survivors.” The last bar of that day was $7.28.

Pre-market: quiet, then $7.84

The first bar on the 2nd opened at $6.55, below the $6.59 close. Through 9:18 a.m. the high was $7.14, set in that very first minute. Most of the morning it sat between about $6.33 and $6.97.

The move came late. At 9:19 a.m. it jumped from $6.74 to $7.25 on 18,542 shares. The pre-market high was $7.84 at 9:24 a.m. 363,851 shares traded before the bell, about 62% of the float. More than half of that traded from 9:19 on.

The open: $7.67 to $10.18

It opened at $7.67, up 16% from the previous close. In the 9:30 minute it cleared the pre-market high, reaching $7.97.

By 9:32 a.m., more shares had traded than exist in the whole float (584,227). The 9:31 minute ran to $8.70 on 149,233 shares. At 9:36:40 a single 19,200-share trade printed at $9.47, at the bid.

At 9:38 a.m. it traded through $10.00 for the first time. The high of that run was $10.18, also at 9:38, up 33% from the open.

The pullback and the $10 area

It pulled back to $9.08 at 9:43. Far below the market, about 50,000 shares had shown up as a bid at $7.45 at 9:39:50. It was pulled at 9:43:00, with the stock above $9. The stock climbed back from there.

At 9:48:05 a buy order swept 23,510 shares from $9.93 to $10.08 across six price levels. A 10,646-share trade printed at $9.93 in the same second.

Here's what happened. The 9:52 minute ran from $10.25 to $11.33 on 467,206 shares, the most of any minute that day. The next minute printed $11.42 at 9:53, up 26% from the $9.08 low.

The headline and the bid at $8.70

At 10:13 a.m. Benzinga ran: “BioAffinity Technologies Stock Skyrockets Wednesday: What's Happening?” The headline came 20 minutes after the $11.42 high. The 10:13 candle fell to $9.61, and by 10:15 the stock was at $9.13.

From 10:21:53 a.m. on, a large bid sat in the book at $8.70. It peaked at 51,540 shares at 10:22:01, about 9% of the float.

The stock stayed above it. At 10:35:31 a sell order swept 23,857 shares from $9.02 to $8.83 across 19 levels. The low while the bid sat there was $8.81 at 10:44, 11 cents above it.

At 11:22:46 a.m. the bid was pulled: the size left the book without trading there. In that same second a new bid appeared at $9.00. It peaked at 31,429 shares at 11:42:28.

What to take from it

• A large bid below the market can vanish without a single share trading there. The 51,540-share bid at $8.70 sat for about an hour and was pulled at 11:22:46 with the stock still above it. The $9.00 bid that replaced it was pulled at 11:53:13, and the stock ran to $11.72.
• A tiny float can trade many times over in minutes. By 9:32 a.m. more shares had traded than the 584,227-share float, and by 10:06 a.m. the total was ten times the float.
• The high of the day can come on a sweep and fade within minutes. At 12:51 a buy order swept 33,749 shares and the minute printed $11.75. Within three minutes the stock was back at $10.75, and the day closed at $9.77.
