The day before
On August 14, GRNQ traded between $7.65 and $9.65. Just 357 shares changed hands that day. The official close was $7.70.
Pre-market: $11.65, then a long drop
The first trades on the 17th came at 5:29 a.m., at $11.31. That was already well above the $7.70 close.
The high so far, $11.65, came at 5:31 a.m. By 5:32 it had traded as low as $8.58. The 5:32 minute was busy for this stock: 10,075 shares.
It did not settle. It dropped to $8.10 at 5:34, down 21% from $10.20 at 5:33. Then it ran back to $10.25 at 5:35, up 27%. That was the last time it traded above $10 until the afternoon.
From there it slid. At 5:46 it hit $5.36, the low so far, down 48% from $10.25 eleven minutes earlier. Of the 107,463 shares traded before the bell, most changed hands in the first 20 minutes after 5:29.
After that, pre-market went quiet. From about 6 a.m. to the open, most minutes had no trades at all. Many that did had fewer than 100 shares. Prices mostly stayed in the high $5s.
The open: $5.60, then a step up
It opened at $5.60, down 27% from the previous close. Through the first half hour it crept up from $5.60 to the $6.00–$6.50 range. Volume stayed small.
At 10:03 it jumped. The minute ran from $6.40 to $7.64 on 1,440 shares and closed at $7.32. That was one of the busiest minutes of the regular session. The whole regular session traded 20,768 shares.
It kept climbing in small steps, around $8.10 by 10:24.
At 10:32:50 it was halted (a volatility pause). The last trade was at $8.18.
Stop It's 10:37. GRNQ has been halted since 10:32:50, after its last trade at $8.18. It's a thin stock with a tiny float. Would you buy when it reopens?
Press play: the real Level 2, time and sales and chart stop at 10:37 a.m. ET for your call, then show what happened. The clip starts at 10:34 a.m. ET.
It reopened at 10:37:50 at $8.50, 4% above where it stopped. That's the number the chart shows. It doesn't show what a bigger order would have paid.
The reopen did not hold. By 10:38 the stock was down to $7.75.
The rest of the day
Trading stayed sparse. Many minutes printed a single trade or none. Through the late morning it mostly sat between about $7.75 and $8.70.
From $7.91 at 11:19 it worked up to $9.50 at 12:32 p.m., up 20%. Note how thin it was: that 12:32 minute traded just 3 shares.
It came back once more. At 3:54 p.m. it pushed to $10.33, a lower high under the $11.65 top from 5:31 a.m.
It closed at $10.25, up 33% on the day from the $7.70 close, even though it had been down as far as $5.36 that morning.
By the close, 128,231 shares had traded (107,463 pre-market and 20,768 in the regular session). That's about a ninth of the float, and 135 times the stock's normal volume. After hours added 1,198 more.
What to take from it
- A thin pre-market spike can unwind just as fast. GRNQ went from $11.65 to $5.36 in 15 minutes, and the whole pre-market was about 107,000 shares.
- On a thin stock, the screen price is not the price you pay. At the 10:37 reopen the screen said $8.54 with 21 shares. A 5,000-share order averaged $9.74.
- After the top, the next push stopped lower. $11.65 at 5:31 a.m., then $10.32 at 3:54 p.m.
