How it traded
Gap and hold. It gapped up 14.0% to 9.71 at the open and held above it, trading at 10.54 at 4:00 p.m.
| Time (ET) | What happened |
|---|---|
| 8:20 a.m. | Pre-market high, 9.99 |
| 9:30 a.m. | The open: 9.71, up 14.0% from the previous close |
| 3:55 p.m. | First trade 20% above the previous close of 8.52 |
| 3:59 p.m. | High of the day to the close, 10.58 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 10.54, 0.4% 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.
