How it traded
Gap, run and fade. It gapped up 25.8% to 2.73 at the open, ran from the open to the high of 3.44 in 31 minutes, then gave back 36% of that move by 4:00 p.m., trading at 3.19.
| Time (ET) | What happened |
|---|---|
| 8:05 a.m. | SEC filing 8-K: 8-K |
| 8:48 a.m. | First trade 20% above the previous close of 2.17 |
| 8:51 a.m. | Pre-market high, 2.99 |
| 9:30 a.m. | The open: 2.73, up 25.8% from the previous close |
| 10:01 a.m. | High of the day to the close, 3.44 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 3.19, 7.4% 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.
