Pre-market: a quiet start, then a headline

The previous close was $1.66. Before 7:30 a.m. the stock barely traded. There were two tiny prints at $1.66, at 4:31 a.m. and 5:19 a.m.

At 7:30 a.m. GlobeNewsWire ran a headline: “New U.S. Patent Allowance Strengthens Protection for CAPTN-3 Modular Platform for Next-Generation Multispecific Antibodies”. The 7:30 minute traded 39,084 shares and closed at $2.20, up 33% from the previous close. The headline and the time are all we know. The data does not say the news caused the move.

At 7:33 a.m. the company filed a 6-K, a foreign company's current report. The stock was trading around $2 at the time.

Volume was heavy from the start. The 7:34 and 7:35 minutes each traded about 275,000 shares or more. By 7:37 a.m., more shares had traded than exist in the whole float (1.60 million).

The 7:37 spike and the drop

At 7:37 a.m. the stock jumped from $2.03 to $2.37 on 657,007 shares. It hit $2.46 at 7:38 a.m. Then it turned. By 7:40 a.m. it was down to $1.93, 22% below that high.

Later, on a bounce to $2.31 at 7:49 a.m., Level 2 showed big buying. At 7:48:50 one order bought 64,631 shares from $2.20 to $2.26 across 7 price levels in 50 milliseconds. At 7:50:19 another bought 53,070 shares from $2.16 to $2.20.

After that it slid. It was near $2.02 at 8:00 a.m. and $1.86 at 8:12 a.m. Volume fell to mostly a few thousand to a few tens of thousands of shares a minute. From 8:07 to 8:41 it stayed between $1.86 and $2.12.

8:42: a slow climb in pre-market

At 8:42 a.m. it began to climb from $2.04. By 8:47 a.m. it traded as high as $2.34 on 403,797 shares.

The 8:49 minute traded 1,953,906 shares. It went from $2.26 to $2.88. A sweep at 8:49:07 bought 39,807 shares from $2.40 to $2.46 across 8 levels. The next minute traded another 1,785,577 shares. The high of the day was $3.00 at 8:50 a.m., up 81% from the previous close.

Within five minutes it was back at $2.37 (the 8:55 low). By 8:55 a.m. the pre-market volume was ten times the float. The pre-market total was 20.41 million shares.

The open and the lower high

It opened at $2.39, up 44% from the previous close. At 9:30:01 a single print of 123,308 shares went through at $2.41.

It had one more push. At 9:33 a.m. it reached $2.59, a lower high under the $3.00 top. A 41,105-share sell sweep went through at 9:33:23 from $2.50 to $2.46. The next minute, 9:34, it dropped to $2.22.

Later tries were smaller. It reached $2.52 at 9:44 and $2.51 at 10:19. At 9:57 a sell sweep of 60,863 shares ran from $2.33 to $2.27.

A quiet midday with bid walls

By 10:48 a.m. it was at $2.07, and volume fell to a trickle. Many minutes traded under 10,000 shares.

Level 2 shows large bids stacking up around noon. From 12:28 to 12:48, six bid walls of about 129,000 to 135,000 shares appeared, each about 8% of the float. They were at $2.21, $2.24, $2.27, $2.22, $2.24 and $2.25. Each was pulled after one to five minutes. The price stayed between about $2.20 and $2.30 the whole time.

The close

The afternoon was a slow drift. It was near $2.40 at 2:35 p.m. Late in the day it broke down. At 3:43 p.m. it fell to $2.17. In the last hour it hit its regular-session low, $1.90, at 3:58 p.m. It closed at $1.97.

The regular session traded 12.32 million shares. After hours added 499,042. The whole day was 33.23 million shares, more than 20 times the float, at about 898 times normal volume. Normal volume is tiny, about 37,000 shares a day.
