Pre-market: the float traded by 7:50 a.m.

The first trades on the 30th were at $2.83 at 4:32 a.m. Trading stayed thin, between $2.74 and $2.95, until 7:45 a.m.

At 7:45 a.m. Accesswire ran this headline: “Valion Bio and Shear Kershman Laboratories Successfully Formulate Oral Mucosal Entolimod; Valion Sees Potential for Multi-Fold Expansion of Long-Term Opportunity”. In that same minute the stock traded from $2.79 up to $3.19, through $3.00. At 7:47 a.m. it reached $3.61.

By the end of the 7:50 minute, more shares had traded than exist in the whole float (763,037). It touched $3.87 at 7:52 a.m. and $3.92 at 8:03 a.m. At 8:10 a.m. it ran to $4.20. Then it fell to $3.25 at 8:15 a.m., down 23% in five minutes. By 8:25 a.m. the volume was ten times the float.

The wall at $3.54

From 8:26 a.m., a large ask wall sat at exactly $3.54. It was still there going into 8:29, a large block of shares offered at a single price. The stock was trading in the mid-$3.40s and had been chopping since the drop to $3.25.

Here's what happened. At 8:29:25 the first trade printed at $3.54. In 9.1 seconds, 70,621 shares traded at exactly $3.54 and the wall was gone. It wasn't pulled. Buyers ate it.

The move didn't carry far. The 8:29 minute topped out at $3.60. A bid wall then appeared at $3.38 at 8:35 a.m. It peaked at 50,365 shares and was pulled at 8:37. The stock pushed to $4.00 at 8:43 a.m., then held in the high $3.70s and low $3.80s. After 9:00 a.m. it climbed again to the pre-market high of $4.23 at 9:10 a.m. 13.96 million shares traded before the bell.

The open

Above the price there was another wall. From 9:01 a.m. a large ask wall sat at $4.50. It was still in the book going into the open. Every high before the bell stayed below it.

The open was $4.01. The first minute was the busiest of the day: 877,085 shares, with a range of $3.79 to $4.35. At 9:30:21 three buy sweeps went through the book within the same second, from $4.18 up to $4.29. The next minute reached $4.38, the high of the day, at 9:31. That's still $0.12 under the wall at $4.50. By 9:32 it traded as low as $3.88.

The drop to $3.47

It pushed back to $4.19 at 9:34. Then at 9:34:59 a 26,901-share sell swept the book from $3.85 down to $3.80. The 9:35 minute fell to $3.53 on 420,735 shares.

A new ask wall appeared at $4.10 at 9:35, peaked at 58,098 shares at 9:38, and was pulled at 9:38. The stock didn't go near it. It fell to $3.47 at 9:42 a.m., down 21% from $4.38.

The rest of the day

It came back once more. At 9:50 a.m. it pushed to $3.79, a lower high under the $4.38 top. A 42,938-share sell swept from $3.51 to $3.45 at 9:59:55, and it fell to $3.17 at 10:07 a.m.

At 10:19 a.m. a 57,159-share buy swept from $3.45 to $3.58. Eight seconds later a 27,647-share sell swept from $3.54 down to $3.46. By 11:09 it was at $3.17, and two more ask walls formed above the price, at $3.76 and then $3.67. The $3.67 wall peaked at 77,204 shares at 12:58 p.m. From 11:09 a.m. until about 3:00 p.m., the price stayed between about $3.05 and $3.30, and volume was thin.

At 3:12 p.m. it dropped from $2.94 and hit $2.53 at 3:13 p.m., the low of the day. It closed at $2.79. After hours it touched $3.00 at 5:30 p.m. and traded at $2.68 by 7:59 p.m.

Through the close, 21.60 million shares traded, 13.96 million of them pre-market: the float changed hands about 28 times, at about 65 times its normal volume. The regular session itself was 7.64 million shares.

What to take from it

• A big ask wall can break fast, and the fill after it can cost more than the screen. The $3.54 wall was eaten in 9.1 seconds, and a 5,000-share buy right after averaged $136 over the screen.
• After the top, the next push stopped lower. $4.38 at 9:31 a.m., then $3.79 at 9:50 a.m.
• The float traded over before the open, and the gap was gone by the close. By 7:50 a.m. more shares had traded than the float holds. The stock closed at $2.79, 36% below the $4.38 high.
