Pre-market: the float traded by 6:48 a.m.

The previous close was $1.12. The day before, only 1,500 shares traded. This is a thin stock.

At 6:00 a.m. GlobeNewsWire ran: “Immuron to launch PROIBS® in the United States”. The first bars after it, from 6:02 a.m., were small. At 6:12 a.m. it was around $1.28 and volume was still small.

The big volume started at 6:13 a.m. From $1.20 at 6:14 a.m. it ran to $1.48 at 6:17 a.m., up 23%. From $1.29 at 6:18 a.m. it ran to $1.60 at 6:27 a.m., up 24%.

By 6:48 a.m., more shares had traded than exist in the whole float (6.47 million).

From $1.56 at 6:53 a.m. it ran to the pre-market high, $1.98 at 7:31 a.m. 33.21 million shares traded before the bell.

At 9:11 a.m. Benzinga ran: “Immuron Stock Surges Friday: What's Driving the Action?”. The stock was around $1.75 then.

The open and the push to $1.99

It opened at $1.81, up 62% from the previous close. The 9:30 minute traded 978,016 shares and dipped to $1.74.

From $1.75 at 9:40 a.m. it worked back up. At 9:45 a.m. it hit $1.99. That minute traded over a million shares. There was also a large ask wall at $2.00 that had first shown up at 7:02 a.m.

Within a minute it was back at $1.85, and by the close of the 9:46 candle it was $1.90.

The bid at $1.84

After the first push faded, a bid wall appeared at $1.84 at 9:41. It peaked at 152,742 shares, about 2.4% of the float.

At 9:49:28 the wall was eaten. 24,558 shares traded at exactly $1.84, and the 9:49 candle fell to $1.82. The stock dropped to $1.71 at 9:54. At 9:56 a new bid wall formed at $1.75.

A lower high at $1.86

The bid at $1.75 grew to 189,635 shares at 9:57, about 2.9% of the float. The stock held at or above it for the next 48 minutes.

It came back once more. At 10:07 a.m. it pushed to $1.86, a lower high under the $1.99 top. A 128,289-share buy sweep went through at 10:30 and moved it from $1.80 to $1.82.

The $1.75 bid was eaten at 10:45:59. 61,003 shares traded at exactly $1.75 in 0.8 seconds. Within eight minutes it was down to $1.66 at 10:53.

The bid at $1.55

A large bid wall at $1.55 was first seen at 6:41 a.m. It peaked at 136,787 shares at 1:18 p.m., about 2% of the float.

From 1:23:57 p.m., in 1.4 seconds 63,929 shares traded at $1.55. The stock's low after the open was $1.54 at 1:24 p.m. It then bounced to $1.65 at 1:34 p.m.

The rest of the day

It closed at $1.78, up 59% on the day. In the last regular-session hour it traded between $1.68 and $1.82.

By the close, 29.66 million shares had traded in the regular session. Counting pre-market too, the float changed hands about 10 times, at over 11,000 times its normal volume (normal is tiny: about 5,600 shares a day).

After hours it traded 2.37 million more shares, with a high of $1.82 at 4:04 p.m. The last bar, at 7:59 p.m., closed at $1.69.

What to take from it

• After the top, the next push stopped lower. $1.99 at 9:45 a.m., then $1.86 at 10:07 a.m.
• Big bid walls are not floors. The $1.84 wall and the $1.75 wall were both eaten, with the heavy trading at each price lasting under a second.
• The float traded over before the open. By 6:48 a.m.
