| 7:00 a.m. | News (GlobeNewsWire): Connect Biopharma Announces Positive Preliminary Topline Data from its Global Phase 2 Study of Rademikibart as an Add-on Treatment for Acute Exacerbations in Adults with COPD and Type 2 Inflammation |
| 7:05 a.m. | SEC filing 8-K: 8-K |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 1.09, 47.4% 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.
The day in numbers
- From news to the move: the first trade 20% above the previous close came 7 minutes after the latest SEC filing before it (8-K, 7:05 a.m.).
- Volume, from the one-minute bars: 44.50 million shares before the 9:30 a.m. open (63%), 11.67 million in the first 30 minutes (17%), and 14.16 million in the rest of the day to 8 p.m. (20%).
- Float rotation, the volume since 4 a.m. against the float of 45.72 million shares: past it once at 9:30 a.m.
- In our recaps, this is the only day CNTB met the small-cap rule.
