Close

$2.12

Pre-market: the float traded by 7:39 a.m.

HYFM closed at $0.54 on July 31. Its float is small, 4.24 million shares. On August 3 the first trade was 55 shares at $0.56 at 7:00 a.m. The next trade came at 7:30.

At 7:30 a.m. GlobeNewsWire ran: “Hydrofarm Completes Sale of Aurora Peat Products and Launches Project Agility to Scale Its Logistics Services Platform”. By 7:31 it had traded as high as $0.78.

The big move was one minute. In the 7:33 candle it went from $0.70 to $2.48 on 555,385 shares, through $1.00 and $2.00. At 7:34 it hit $2.89. In that same 7:34 candle it fell to $1.30. By 7:39 a.m., more shares had traded than exist in the whole float.

It built again. At 7:48 it traded through $3.00 for the first time and reached $3.80 at 7:49. Then it chopped between about $3.00 and $3.82. At 7:58 it hit $4.12, the high so far, up 664% from the previous close. The 7:58 candle closed at $3.49.

It touched $4.12 again at 8:22, after a buy sweep at 8:21:47 took 62,403 shares from $3.69 to $3.90 across 22 price levels. The 8:22 candle closed at $3.67.

The last push came at 9:14, when a buy sweep took 56,352 shares from $3.63 to $3.73. It topped at $3.73, a lower high under $4.12, and drifted to $3.10 by 9:29. Pre-market volume was 37.98 million shares.

The open and the wall at $2.51

It opened at $3.11, up 477% from the previous close, and was halted at 9:30:49 (a volatility pause). It reopened at 9:35:49 around $2.89.

Right after that reopen, a wall of stock appeared at $2.74. It peaked at 230,748 shares at 9:36:05, about 5.4% of the float. Two seconds later the stock was halted again. It reopened at 9:41:07 around $2.66, and the wall was pulled at 9:41:23.

A new wall had already started at $2.51, first seen at 9:41:09. It peaked at 256,041 shares at 9:41:22, about 6.0% of the float. That was the second the third halt began. Each reopening so far had been lower: $2.89, then $2.66.

At 9:46:22 it reopened with a single print of 228,596 shares at $2.50. Buy sweeps followed at 9:46:24 and 9:46:28 (the second took 68,747 shares from $2.49 to $2.63). Then the wall was gone. Buyers ate it. The last 30,372 shares traded at $2.51 within one second, and by 9:46:29 it was cleared.

Halt after halt

The 9:46 candle closed at $2.65. It was halted again 22 seconds after the reopen, at 9:46:44, and then at 9:52, 10:02, 10:07, 10:18 and 10:24. That is six more halts in 38 minutes. The reopens ran from about $2.70 at 9:51 to $2.15 at 10:17, with bounces to $2.47 at 10:07 and $2.29 at 10:23.

The halt at 10:24:26 began after a last trade at $2.14. It lasted ten minutes.

It reopened at 10:34:27 at $1.80, 34 cents under where it stopped. A single print of 147,040 shares crossed at $1.80. It was halted again 24 seconds later.

It reopened at 10:39:51 around $1.95, with a 98,085-share print at $1.95. It climbed to $2.28 by 10:48. It was halted at 10:41, 10:48 and 10:53, and the 10:53 halt ended at 10:58:57 with the stock back near $2.05.

Walls on the way down, and a bounce

Two more ask walls showed up right at halts. At 11:08 a wall peaked at 224,227 shares at $1.94 (5.3% of the float) as the stock was halted. It was pulled at 11:09:41. At 11:33 another peaked at 274,503 shares at $1.55 (6.5% of the float) at 11:33:25, also the moment of a halt. It was pulled at 11:35:07.

Buy sweeps hit near $1.60. A buy sweep took 92,230 shares at 11:38:50 from $1.60 to $1.70, and another took 99,224 shares at 11:41:39. The low after the open was $1.45 at 11:54.

From there it climbed to $2.32 by 12:26. At 12:26 a bid wall of 316,792 shares sat at $2.32, about 7.5% of the float. It was pulled at 12:27:52. At 12:31:23 a sell sweep of 66,196 shares ran from $2.32 down to $2.18, and an ask wall peaked at 244,305 shares at $2.18 at 12:31:41. The halt came two seconds later. The wall was pulled at 12:36:44, and the stock reopened around $2.06.

After a halt at 12:39 it traded mostly between $2.00 and $2.35 until 2:57 p.m. Then it moved again. A buy sweep at 3:00:15 took 60,336 shares from $2.30 to $2.35. It was halted at 3:00:34 and reopened at 3:05:34 around $2.37, reaching $2.54 at 3:06. A last halt came at 3:27:31, with the reopen at $2.09.

The close and after hours

It closed at $2.12, 49% under the $4.12 high. That high came at 7:58 a.m., before the bell, 32% above where it opened. HYFM was halted 25 times in the regular session.

The regular session (9:30 to 4:00) traded 26.82 million shares, about 6 times the float. Pre-market had added 37.98 million before that, and after hours added 3.05 million.

After hours the 4:25 p.m. candle swung between $1.57 and $2.10. It then climbed to $2.30 by 4:34 p.m. and drifted down to $1.78 by 7:59 p.m.

What to take from it

• A halt can reopen far from where it stopped. The 10:24 halt began after a $2.14 trade and ended at $1.80.
• Thin books cost you right after a wall breaks or a halt reopens. Here a 5,000-share buy cost $149 more than the screen at 9:46:30 and $154 more at 10:34:28.
• Once the high is in, lower highs can follow. $4.12 at 7:58 and 8:22, then $3.73 at 9:14, and a $3.11 open. The day ended at $2.12.
