How it traded
Gap and go. It gapped up 29.7% to 26.36 at the open, ran from the open to the high of 30.34 in 157 minutes, and held most of the move into the close: it gave back 23% of it by 4:00 p.m.
| Time (ET) | What happened |
|---|---|
| 5:09 a.m. | First trade 20% above the previous close of 20.32 |
| 9:28 a.m. | Pre-market high, 26.37 |
| 9:30 a.m. | The open: 26.36, up 29.7% from the previous close |
| 12:07 p.m. | High of the day to the close, 30.34 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 29.42, 3.0% 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.
