How it traded
Gap, run and fade. It gapped up 88.8% to 30.51 at the open, ran from the open to the high of 35.86 in 24 minutes, then gave back 41% of that move by 4:00 p.m., trading at 33.64.
| Time (ET) | What happened |
|---|---|
| 7:19 a.m. | First trade 20% above the previous close of 16.16 |
| 9:21 a.m. | Pre-market high, 31.23 |
| 9:30 a.m. | The open: 30.51, up 88.8% from the previous close |
| 9:54 a.m. | High of the day to the close, 35.86 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 33.64, 6.2% 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.
