How it traded
Gap, run and fade. It gapped up 13.0% to 1.02 at the open, ran from the open to the high of 1.22 in 13 minutes, then gave back 90% of that move by 4:00 p.m., trading at 1.04.
| Time (ET) | What happened |
|---|---|
| 8:40 a.m. | SEC filing SCHEDULE 13D: |
| 9:15 a.m. | News (GlobeNewsWire): Special Committee of Definitive Healthcare Board Confirms Receipt of Going-Private Proposal from Advent International |
| 9:16 a.m. | SEC filing 8-K: 8-K |
| 9:29 a.m. | Pre-market high, 1.05 |
| 9:30 a.m. | First trade 20% above the previous close of 0.9023 |
| 9:30 a.m. | The open: 1.02, up 13.0% from the previous close |
| 9:43 a.m. | High of the day to the close, 1.22 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 1.04, 14.8% 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.
