How it traded
Gap, run and fade. It gapped up 14.2% to 1.53 at the open, ran from the open to the high of 2.39 in 87 minutes, then gave back 62% of that move by 4:00 p.m., trading at 1.86.
| Time (ET) | What happened |
|---|---|
| 6:30 a.m. | First trade 20% above the previous close of 1.34 |
| 6:31 a.m. | Pre-market high, 1.70 |
| 9:30 a.m. | The open: 1.53, up 14.2% from the previous close |
| 10:57 a.m. | Volume since 4:00 a.m. passes the whole float, 8.43 million shares |
| 10:57 a.m. | High of the day to the close, 2.39 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 1.86, 22.2% 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.
