When does today’s 9 count for Sionna Therapeutics, Inc.?
Sionna Therapeutics, Inc. is US listed (Nasdaq). The daily 9 waits for the 16:00 New York cash close. Pre-market and after-hours are not the cash close. A 60- or 120-minute 9 is another clock. Do not paste it into the same “today’s daily 9” line.
