How it traded
Intraday run. It opened up 6.6% at 5.50, then ran from the open to the high of 6.10 in 350 minutes.
| Time (ET) | What happened |
|---|---|
| 7:30 a.m. | SEC filing 4: 4 |
| 7:55 a.m. | News (GlobeNewsWire): Quantum X Labs Launches Quantum-Native Cybersecurity Program Designed to Harness Quantum Properties for Next-Generation Security |
| 8:02 a.m. | Pre-market high, 5.60 |
| 9:30 a.m. | The open: 5.50, up 6.6% from the previous close |
| 3:20 p.m. | High of the day to the close, 6.10 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 5.78, 5.2% 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.
