How it traded
Intraday run. It opened up 8.4% at 16.29, then ran from the open to the high of 18.90 in 55 minutes.
| Time (ET) | What happened |
|---|---|
| 8:00 a.m. | News (GlobeNewsWire): Weight Watchers and Google Health Enterprise Launch New Collaboration to Enhance Engagement and Outcomes in Weight Health Programs |
| 8:43 a.m. | Pre-market high, 17.06 |
| 9:30 a.m. | The open: 16.29, up 8.4% from the previous close |
| 10:14 a.m. | First trade 20% above the previous close of 15.03 |
| 10:25 a.m. | High of the day to the close, 18.90 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 17.13, 9.4% 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.
