The day before

On September 22, GRML ran from $9.80 to $18.15. It gave some of it back and closed at $14.14. About 43.6 million shares traded that day, roughly ten times the float.

At 12:00 on the 22nd, GlobeNewsWire ran: "Greenland Mines Applauds Formal Signing of U.S.-Denmark-Greenland Security Agreement at United Nations".

Pre-market: the float traded by 7:07 a.m.

The first trades on the 23rd were at $15.88, already above the $14.14 close. The 4:00 minute touched $17.00. By 4:23 a.m. it was down to $15.22.

It then drifted near $15.60 to $16.00 for half an hour. At 5:33 a.m. a single minute traded 194,441 shares and hit $19.51, up 38% from the previous close. At 5:54 a.m. another minute traded 189,861 shares and reached $20.50.

At 6:15 a.m. it hit $21.86. That minute traded 152,412 shares. Within two minutes it was back at $19.57.

By 7:07 a.m., more shares had traded than exist in the whole float (4.38 million). At 7:00 it had dropped from $20.07 to $18.84 in one minute, on 151,333 shares.

It slid to $17.06 at 7:28 a.m., 22% under the high. Then it climbed again. At 7:58 a.m. it pushed to $18.88, a lower high under $21.86.

A headline and a filing before the open

At 8:30 a.m. GlobeNewsWire ran: "Greenland Mines Ltd. (NASDAQ: GRML) Applies to More than Double Mining Footprint in West Greenland". That minute traded 183,795 shares between $17.20 and $18.53 and closed at $17.60.

At 9:28 a.m. the company filed a 424B5 prospectus (a shelf offering's terms). That minute went from $17.73 to $14.68 on 524,165 shares. At 9:28:34 one sell order swept 43,468 shares from $16.55 to $15.77 across 74 price levels. In the next minute it ran back up to $18.82.

The filing and the swing share a minute. That is all the data shows.

The open and the wall at $16.89

It opened at $17.38, up 23% from the previous close and about 20% under the pre-market high. At 9:30:01 a single trade of 150,435 shares printed at $17.24. The 9:30 minute alone traded 505,007 shares. By 9:39 it had dropped to $15.01.

Here is what a chart doesn't show. At 9:55, an ask wall appeared at exactly $16.89. By 9:55:17 it showed 152,320 shares, about 3.5% of the float. A second ask wall had been at $17.00 since 9:46.

Here's what happened. The 9:56 minute touched $16.89 and no higher. The next minute it fell to $15.89. The wall stayed on the book.

After the wall

At 10:03:19 a 50,000-share trade printed at $15.90, at the ask. Then the selling came in blocks. Sell orders swept the book at 10:08:22 (53,544 shares), 10:09:16 (58,525) and 10:11:16 (42,857). The 10:12 minute hit $13.90 on 297,740 shares.

It kept falling. At 10:16:31 another sell order swept 55,976 shares from $13.07 to $12.88 across 19 levels. At 10:18 it hit $12.24, 28% under the wall price.

Then it bounced. At 10:25:56 a buy order swept 44,050 shares from $13.31 to $13.69. A bid wall appeared at $13.50 and grew to 143,284 shares at 10:27:16. It was pulled at 10:27:35. By 10:39 the price was $12.08, and at 10:43 it touched $11.90. A 10:45 spike reached $13.30 and didn't hold.

It spent the late morning near $11.50 to $12.50. At 1:07 p.m. a 52,389-share trade printed at $12.00, at the bid. At 1:18 p.m. a 198,314-share minute dropped it from $11.51 to $10.65. The low of the day was $10.29 at 1:40 p.m. It got back to $12.12 by 3:31. At 3:44:38 p.m. the $16.89 wall was pulled, and the stock had never traded above $16.89 again after 9:56. Then three trades of 22,000 to 25,000 shares hit the bid between 3:55 and 3:58, at $11.69, $11.40 and $11.20.

The 3:59 minute ended at $11.20, 49% under the $21.86 high. That high came at 6:15 a.m., 26% above the open. In the regular session 17.10 million shares traded, on top of 9.14 million pre-market. Together that is about 6 times the float, at about 3.9 times normal volume.

After hours

It ran from $11.03 to $13.10 by 4:58 p.m. At 5:08 p.m. the company filed an 8-K (a current report). The price was $12.38 then, and by 5:10 it had traded as low as $11.30.

At 5:23 p.m. the company filed another 424B5 prospectus. After hours it traded between $11.02 and $14.40, with the high at 7:08 p.m. About 1.91 million shares traded after the bell.

What to take from it

• After 9:56, GRML never traded above its $16.89 ask wall. It touched $16.89 that minute; the wall stayed on the book until 3:44:38 p.m.
• The high of the day came before the regular session. $21.86 at 6:15 a.m. was 26% above the open. A trader who first looked at 9:30 saw a stock already about 20% off its top.
• Filings can arrive at any hour. This day had a 424B5 at 9:28 a.m., before the open, and another at 5:23 p.m., after the close.
