The day before
On September 15, BYAH traded between $2.40 and $2.89, and the official close was $2.74. Volume was 57,149 shares.
Two law-firm alerts about a class action against the company went out that day. One ran at 11:39 a.m. (GlobeNewsWire, "BYAH Shareholder Alert"). The other ran at 5:17 p.m., after the close (GlobeNewsWire, "INVESTOR ALERT: Pomerantz Law Firm Reminds Investors with Losses..."). Both are reminders about a lawsuit and deadlines, not business news.
Pre-market: a one-minute spike to $4.24
The first minute of the day, 4:00 a.m., opened at $2.73. It hit $4.24 and closed the minute at $3.80. Only 8,912 shares traded in that minute.
The next minute it was back down to $2.58 at the low. By 4:03 it was near $2.88. After that it mostly traded between $2.60 and $2.98 on thin volume, with many minutes having no trades at all. 106,837 shares traded before the bell. The stock's float is 2.9 million shares.
The open and a quiet first 13 minutes
It opened at $2.88, up 5% from the $2.74 close. For the first 13 minutes it stayed between $2.67 and $2.91.
Then at 9:43 it began to move. The 9:43 minute went to $3.10, and 9:44 to $3.28. At 9:45, 86,146 shares traded and it reached $3.77. At 9:46 it hit $3.95, the high since the open. That was below the $4.24 pre-market high. Around 302,000 shares traded in the three minutes from 9:45 to 9:47.
The halt and the reopen
The 9:48 minute opened at $3.61 and ended at $2.89. At 9:48:30 the stock was halted (a volatility pause) with the last trade at $2.89. That was 27% under the $3.95 high set at 9:46–9:47.
Stop It's 9:53. BYAH was halted at 9:48 with the last trade at $2.89, after a run to $3.95 at 9:46. The reopen is seconds away. Would you buy the reopen?
Press play: the real Level 2, time and sales and chart stop at 9:53 a.m. ET for your call, then show what happened. The clip starts at 9:50 a.m. ET.
Here's what happened. It reopened at 9:53:30 at $2.84. At 9:53:30 a single print of 13,248 shares crossed at $2.84 on Nasdaq. The stock then fell for four minutes and hit $2.04 at 9:57, the low of the day.
The rest of the day
From 10:00 it traded mostly between about $2.17 and $2.45 until a push to $2.57 at 10:58. At 10:07 a.m. PRNewsWire ran another class-action alert: "BYAH UPCOMING DEADLINE: Levi & Korsinsky Alerts Park Ha Biological Technology Co., Ltd. Stockholders...". A third alert ran at noon (GlobeNewsWire, Bronstein, Gewirtz & Grossman). Volume was light for most of this stretch.
It drifted higher into late morning, reaching $2.74 at 11:14. It then slipped back, with a dip to $2.27 at 11:27. From noon on it mostly traded between $2.20 and $2.50. The 3:59 p.m. minute closed at $2.28, and a $2.37 print came at 4:00 p.m. That $2.28 is 46% under the $4.24 high, which came before the bell.
720,876 shares traded in the regular session, about a quarter of the float. Including pre-market and after hours, the day's total was 838,078 shares, about 43 times normal volume. Normal volume is small, about 19,000 shares a day.
After hours it bounced to $2.65 at 6:38 p.m. and reached $2.69 in the 7:59 p.m. minute, which closed at $2.65. After hours volume was 10,365 shares.
What to take from it
- A spike on almost no volume is not the same as a move. The $4.24 print at 4:00 a.m. came on 8,912 shares and was back near $2.58 a minute later.
- The second push stopped lower. $4.24 at 4:00 a.m., then $3.95 at 9:46 a.m., then a halt and a low of $2.04 within 11 minutes.
- At this reopen, a fill one second in cost more than the screen showed. A 5,000-share market buy averaged $2.88 against $2.82 on screen.
