How it traded
Gap, run and fade. It gapped up 26.0% to 5.04 at the open, ran from the open to the high of 8.79 in 313 minutes through a halt, then gave back 38% of that move by 4:00 p.m., trading at 7.38.
| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | First trade 20% above the previous close of 4.00 |
| 8:42 a.m. | Pre-market high, 5.66 |
| 9:30 a.m. | The open: 5.04, up 26.0% from the previous close |
| 10:58 a.m. | Halted: LULD pause (limit up-limit down). Trading resumes at 11:03 a.m. |
| 12:00 p.m. | Volume since 4:00 a.m. passes the whole float, 20.52 million shares |
| 2:43 p.m. | High of the day to the close, 8.79 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 7.38, 16.0% below the high |
The shape is a fixed rule, not a judgement: gapped 10% or more at the open, ran 10% or more from the open to the high, and faded if it gave back 30% or more of that move by the close.

- Float rotation, the volume since 4 a.m. against the float of 20.52 million shares: past it once at 12:00 p.m.
- The halt at 10:58 a.m.: up 13.7% in the 5 minutes into it, reopened at 6.10, down 3.0% from the last trade before it, then up 2.5% over the next 5 minutes.
