The day before

On August 25, NUWE opened at $1.05, reached $1.22, dipped to $0.935 and closed at $0.96.

That morning at 8:30 a.m., GlobeNewsWire carried the headline "Nuwellis Expands Critical Care Portfolio Through Strategic Commercial Agreement with Atrility Medical." Nothing else was filed or announced before the next day's session.

Pre-market: the first push and the drop

The first trades on the 26th were at $0.98 at 4:16 a.m., just above the $0.96 close. It then sat near $0.98 to $1.00 for hours, on thin volume.

At 6:45 a.m. it moved. By 6:49 a.m. it hit $1.26, up 28% from $0.98. That one minute traded 175,380 shares.

Then it gave it back. It slid through $1.05 and fell to $0.97 at 7:13 a.m., down 23% from $1.26.

The wall at $1.17 and $1.18

At 6:49:54 a.m. a big ask wall showed up at $1.19. It peaked at 118,655 shares at 6:53:18 a.m., about 3.2% of the float, then was pulled at 6:53:25. In the same seconds new walls appeared just below it. One was at $1.18, up to 110,224 shares. The other was at $1.17, up to 76,699 shares at 6:53:29, about 2.1% of the float.

They stayed on the book for the next hour while the price slid to $0.97 and climbed back. By 7:51 a.m. NUWE was at $1.14 and pressing up into them.

Here's what happened. At 7:52:04 the first trade printed at $1.17. In 5.7 seconds, 12,946 shares traded at exactly $1.17 and that wall was gone. The $1.18 wall followed. 11,764 shares traded at $1.18 over 4.2 seconds, and it was eaten at 7:52:28.

It went from $1.14 at 7:51 to $1.29 at 7:53 a.m., up 33% from the $0.97 low at 7:13.

After the wall broke

It pulled back to $1.11 at 7:56, then worked up again. At 8:02 it dipped to $1.11 and at 8:03 it opened at $1.16.

The next minute went to $1.37. At 8:05 a buy order swept 19,169 shares from $1.35 to $1.37, and the stock touched $1.41. At 8:06 it opened at $1.32. Then at 8:07 it pushed to $1.45, the high of the day. That minute traded 498,021 shares, the most of any minute that day.

By 8:10 it was back at $1.24. At 8:08:08 a sell order took 15,880 shares from $1.27 to $1.25. One second later a buy swept 13,963 shares from $1.24 to $1.28, and it didn't hold. At 8:11 it touched $1.18, about four minutes after the high.

During the 8:08 minute, more shares had traded than exist in the whole float (3.65 million). In pre-market it traded 6.43 million shares in all.

It tried once more. At 8:13 a.m. it pushed to $1.28, a lower high under the $1.45 top, and it hit $1.28 again at 8:27. It never got back to $1.30 after 8:08.

The fade into the open

From 8:34 a.m. another ask wall built at $1.16 and peaked at 100,291 shares at 8:35:17, about 2.8% of the float. It was pulled at 8:36:59. During those minutes a sell order took 19,859 shares from $1.15 to $1.13. At 8:45 another sold 30,751 shares from $1.13 to $1.10.

At 8:52 the stock was at $1.06, and at 9:00 it dipped to $0.99. It was back to $1.04 by the open.

The 9:30 open was $1.04, up 8% from the $0.96 previous close. The first minute traded 27,045 shares, less than 0.5% of the 6.43 million traded in pre-market. It dropped to $0.98 by 9:36 and hovered near $1.00 to $1.04.

The rest of the day, and after hours

Late morning it bounced to $1.10 at 11:10, then drifted down. The low after the open was $0.98 at 2:40 p.m. It crept back to $1.02 in the last hour, and at 3:59 p.m. it was $1.00.

The regular session (9:30 to 4:00) traded 1.23 million shares. Pre-market was 6.43 million and after hours 187,921. For the whole day, 7.85 million shares traded: the float changed hands a little over 2 times, at about 1.8 times its normal volume.

At 5:15 p.m. the company filed a 424B3 prospectus. The stock was around $0.98 then and traded between $0.97 and $1.03 into the evening.

What to take from it

• A wall that sits for an hour can break in seconds. The $1.17 wall stood from 6:53 to 7:52 a.m., then 12,946 shares traded through it in 5.7 seconds and the stock ran from $1.14 to $1.29 within two minutes.
• After the top, the next push stopped lower. $1.45 at 8:07 a.m., then $1.28 at 8:13.
• The move happened before the open. During the 8:08 minute, more shares had traded than the float holds. The open was $1.04, 28% below the $1.45 high.
