How it traded
Gap and go. It gapped up 26.6% to 3.00 at the open, ran from the open to the high of 4.87 in 374 minutes, and held most of the move into the close: it gave back 19% of it by 4:00 p.m.
| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | First trade 20% above the previous close of 2.37 |
| 6:24 a.m. | Pre-market high, 3.31 |
| 9:30 a.m. | The open: 3.00, up 26.6% from the previous close |
| 9:35 a.m. | Volume since 4:00 a.m. passes the whole float, 6.51 million shares |
| 3:44 p.m. | High of the day to the close, 4.87 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 4.51, 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.
