The day before

On September 18, GRML opened at $2.96 and ran to $4.82. It gave all of it back and closed at $2.85, below its open.

Its last trade of the day, possibly after hours, was at $4.53.

Pre-market: the float traded by 7:05 a.m.

The first trades on the 21st were at $5.01, already well above the $2.85 close. In that first minute it touched $6.50.

At 4:47 a.m. CNBC ran: “U.S.-listed Greenland stocks surge after Trump agrees security deal with Denmark”. The stock was around $4.86 that minute, and it kept drifting lower. It hit $4.40 at 6:49 a.m., the low so far and 32% under that $6.50.

By 7:05 a.m., more shares had traded than exist in the whole float (4.36 million). From $4.72 at 7:05 it climbed to the pre-market high, $8.20 at 8:31 a.m. 26.83 million shares traded before the bell.

The open and the bid at $7.00

It opened at $7.33, up 157% from the previous close. At 9:30 a GlobeNewsWire headline came out: “Greenland Mines More Than Doubles Control Position in the Sarfartoq Rare Earth Magnet District in West Greenland”. The first minute traded 1.1 million shares and ran to $7.90.

From 9:34 on, someone was bidding for a lot of stock at exactly $7.00, across all exchanges. The stock sat just above it.

The bid peaked at 95,036 shares at 9:42:00, about 2.2% of the float. At 9:42:22 trades started printing at $7.00. In 7.5 seconds, 92,742 shares traded at exactly $7.00 and the wall was gone. It wasn't pulled. Sellers hit it. The 9:42 minute low was $6.77.

It recovered to $7.41 by 9:48, then slid. From $7.23 at 9:52 it dropped to $6.63 at 9:55, the low since the open.

The ask wall at $8.00

Above the stock, a different wall had been building. Someone was offering stock at exactly $8.00 from 8:34 a.m. It peaked at 97,873 shares at 9:39, also about 2.2% of the float.

The stock chopped between about $6.60 and $7.40 for the next hour. A 135,868-share bid at $6.75 appeared at 10:24 and was pulled at 10:25:47, two seconds after its peak. At 10:44:03 a buy sweep of 74,700 shares ran $7.43 to $7.50. It reached $7.80 at 10:45, and by 10:46 it was back to $7.00.

At 10:54:39 one buy order swept 158,901 shares from $7.76 to $8.00 across 25 levels. 58,376 shares traded at exactly $8.00 in that one second, and the wall was eaten at 10:54:40. It cleared the pre-market high. The 10:54 minute reached $8.54, up 26% from $6.77 at 10:30.

The next minute it fell back to $7.13. From $7.07 at 10:56 it ran again to $9.84 at 11:06, up 39%.

Late morning: the run past $9

At 11:21:37 a buy sweep of 60,731 shares ran $10.93 to $11.07. The minute topped at $11.69, the high of the day, up 310% from the previous close. The next two minutes gave back to $10.86.

The rest of the day, and after hours

At 11:49 it pushed to $10.77, another lower high. At 12:03 it dropped from $10.12 to $9.25 in one minute, and it hit $8.19 at 12:26.

Then the last two minutes. The stock was $9.98 at 3:57 and fell to $9.32 by the end of 3:58. It closed the regular session at $9.41.

The regular session traded 58.94 million shares, about 13.5 times the float. With 26.83 million pre-market and 7.46 million after hours, the whole day was 93.22 million shares: the float changed hands about 21 times, at 189 times normal volume. There were no halts.

After hours it traded between $8.52 (5:06 p.m.) and $11.20, with the high at 6:26 p.m. It jumped from $10.19 to $10.97 in the 6:17 minute. The last price in our data is $10.94 at 7:59 p.m.

What to take from it

• Walls break on both sides. A 95,000-share bid at $7.00 was gone in 7.5 seconds, and a 98,000-share ask at $8.00 went in one second.
• Right after the $8.00 wall broke, a market buy cost more than the screen showed. At 10:54:41 the screen showed $8.34 with 216 shares, and 5,000 shares averaged $8.50.
• The float traded over by the end of the 7:05 a.m. minute. The stock was in play long before the open, and the high of the day came at 11:21, well after the open.
