The day before
On October 12, BKHA traded from $11.95 up to $23.00. It closed at $13.00, well off that high. Volume that day was 28,711 shares.
The float is small: 425,706 shares. That matters for everything below. A few hundred shares can move this stock.
Pre-market: a handful of shares
The first trade on the 13th came at 4:13 a.m. at $12.02, below the $13.00 close. After that it traded only now and then, mostly between $12.01 and $12.99.
The pre-market high was $13.00 at 5:11 a.m. In all, 351 shares traded before the bell. That is under a tenth of one percent of the float.
The open and the $13.77 spike
It opened at $12.99, one cent under the previous close. The first minute traded 25 shares.
At 9:34 it ran from $12.99 to $13.76 on 537 shares. Then at 9:37 it printed $13.77, the high of the regular session, on 720 shares. By 9:38 it was trading at $12.87.
Later, at 10:16 it traded $13.36 on 816 shares, and at 10:20 it printed $13.75 on 100 shares. Neither got through $13.77. By 10:36 it was back at $12.95, and it spent most of the late morning around $12.95 to $13.00.
Halt one: the drop and the $9.50 reopen
At 11:38 the stock broke down. In one minute, 1,712 shares traded and the price went from $12.74 to $11.30. That one minute was more than a fifth of the regular-session volume. By 11:41 it was back at $12.00.
At 11:44 it was halted (a volatility pause), with the last trade at $12.00. It reopened at 11:58 at $9.50, 21% below where it stopped. The halt lasted about 14 minutes.
Halt two: the $8.73 low and the $12.00 reopen
Right after the reopen it hit $8.73 at 11:59, down 37% from the $13.77 high. It touched $8.73 again at 12:00 and 12:01. The price jumped between $8.73 and $10.45 in those first few minutes.
At 12:04 it was halted again, with the last trade at $10.45. It reopened at 12:14 at $12.00, 15% above where it stopped. This time the reopen was higher, not lower.
The afternoon and the close
The rest of the session was thin and traded between about $10.80 and $12.75 until the last minute. Many minutes had no trades. At 3:59 p.m. it pushed to $12.86 on 203 shares, and that was the regular-session close, down 1% from $13.00.
Regular-session volume was 8,451 shares, about 2% of the float.
After hours: the 8-K
The real action came after the bell. At 4:16 p.m. the company filed an 8-K (a current report). The stock traded at $14.00 in the 4:17 minute and at $16.00 by 4:18.
The high of the day was $19.50, in the 4:19 minute, when 18,658 shares traded in that one minute. The stock then fell. Its after-hours low was $11.21 at 4:32 p.m., down 43% from $19.50.
It recovered to $13.50 by 4:45 and traded mostly between about $12.80 and $14.50 until 8 p.m. The last bar, at 7:59 p.m., closed at $12.99.
After hours, 155,617 shares traded, against 8,451 in the whole regular session. For the whole day, 164,419 shares traded.
What to take from it
- A halt can reopen lower than it stopped, or higher. The 11:44 halt stopped at $12.00 and reopened at $9.50. The 12:04 halt stopped at $10.45 and reopened at $12.00.
- In a very low-float stock, a few hundred shares set the price. The $13.77 high came on 720 shares, and the regular session saw 8,451 shares in all.
- After hours can be the main event, and it can undo itself fast. The stock traded at $19.50 at 4:19 p.m. and at $11.21 by 4:32 p.m.
