| 7:00 a.m. | News (GlobeNewsWire): Opus Genetics Announces Positive Low Dose Cohort 1 Data from Phase 1/2 Clinical Trial of OPGx-BEST1 and Successful FDA Type C Meeting with Potential Phase 3 Dosing in 2027 |
| 7:30 a.m. | SEC filing 8-K: 8-K |
| 8:27 a.m. | First trade 20% above the previous close of 4.34 |
| 8:56 a.m. | Pre-market high, 5.52 |
| 9:30 a.m. | The open: 5.30, up 22.1% from the previous close |
| 9:48 a.m. | High of the day to the close, 7.07 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 5.72, 19.1% 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.
