Pre-market: quiet, then 8:10

The official previous close was $0.93. The first trade on the 8th was at 4:00 a.m., at $1.00, already above that close.

For the next four hours it mostly drifted between about $0.95 and $0.98 on thin volume. The pre-market low was $0.9462 at 4:49 a.m. By 8:00 it was still at $0.97.

Then it started to climb. It was at $1.00 by 8:02 and $1.09 by 8:07. At 8:10 a.m. Business Wire ran: “Mobix Labs Secures Initial F-16 Component Order, Expanding U.S. Fighter Aircraft Footprint.” That minute traded 217,842 shares, far more than any minute before it. By 8:11 the high was $1.18.

It kept climbing: $1.24 at 8:17, $1.36 at 8:23, and the pre-market high, $1.40 at 8:26 a.m. Then it slid to $1.16 at 8:33, down 17% from the top. After that it held mostly between $1.17 and $1.28 until the open. 13.20 million shares traded before the bell.

The open

It opened at $1.18, up 27% from the previous close. A 46,101-share print at $1.18 came at 9:30:01. The stock then dropped. It fell to $1.11 at 9:31, the low since the open.

It base-built around $1.11 to $1.21 for the next several minutes. At 9:40 Business Wire ran a shorter headline: “Mobix Labs Secures Initial F-16 Component Order.” It carries the same news as the 8:10 headline, in fewer words.

By 9:41, more shares had traded than exist in the whole float (15.33 million). That minute went from $1.23 to $1.29 on 727,432 shares.

The wall at $1.30

Starting at 8:33 a.m., there was an ask wall at $1.50. At 8:40 a wall also showed up at $1.30. By 9:46 it peaked at about 157,000 shares for sale at exactly $1.30, about 1% of the float. Below the price, a bid wall of up to about 167,000 shares formed at $1.20 from 9:40.

The stock spent several minutes below $1.30, between $1.21 and $1.29.

Here's what happened. From 9:53:36 to 9:53:43, 116,642 shares traded at exactly $1.30. At 9:53:44 the wall was gone. Buyers ate it in about six seconds.

The wall at $1.40

The 9:54 candle ran to $1.41 on 1.25 million shares, the heaviest minute of the morning. A 136,553-share buy sweep at 9:54:09 went from $1.36 to $1.39 across four levels. Then a new ask wall showed up. At 9:54:56 there were offers at $1.40, and the wall grew to 145,660 shares by 9:57:57.

Here's what happened. From 9:58:00 to 9:58:17, 165,032 shares traded at exactly $1.40. The wall was gone by 9:58:18. Seven seconds later a 153,307-share buy sweep ran from $1.42 to $1.47 across five levels. $1.47 was the high of the 9:58 minute.

It did not hold. The 9:59 candle closed at $1.33, and by 10:00 the low was $1.26. That is below the $1.40 where the 9:58 minute began, within about two minutes of the high.

The rest of the day

It climbed again. At 10:08 it matched $1.47, then slid. A new ask wall showed at $1.55 from 10:11. By 10:20 it was down to $1.29.

Here's what happened. At 10:48:29 a 110,605-share sell sweep went from $1.30 to $1.27. Two seconds later an 80,310-share sell went from $1.27 to $1.25, and the $1.25 bid wall was eaten at 10:48:32. The 10:48 candle touched $1.24, down 16% from $1.47, on 525,464 shares.

It chopped from there between $1.24 and $1.38. At 11:54 it pushed to $1.38, a lower high under $1.47. After that it faded: $1.32 at noon, a $1.25 low at 1:05 p.m., and about $1.27 at the 4:00 p.m. close.

The regular session traded 27.54 million shares by the close, about 1.8 times the float. After hours added 1.12 million more. The stock bounced to $1.35 by 4:44 p.m. and faded to about $1.25 by 8:00 p.m.

What to take from it

• Big ask walls at round-number prices are levels, and buyers can eat them in seconds. Here $1.30 went in about six seconds and $1.40 in 17. The question is what happens in the minutes after.
• Breaking a wall doesn't mean it holds. The $1.47 high came seven seconds after the $1.40 wall broke, and the stock was back at $1.26 about two minutes later.
• After the top was matched, the later push stopped lower. $1.47 at 9:58 and again at 10:08, then $1.38 at 11:54.
