Frequently Asked Questions
What is SION's after-hours price?
Sionna Therapeutics (SION) is trading at $7.14 after hours, up $0.10 (1.42%) from its regular-session close of $7.04.
Why is SION moving after hours?
SION is up 1.42% in after-hours trading. Moves in this session almost always follow something released after the 4:00 PM ET close — an earnings report, guidance, a filing, or news — and trade on far thinner volume than the regular session, so the size of the move can overstate what the market will settle on at the next open.
When does SION after-hours trading start and end?
After-hours trading in SION on the NASDAQ runs from 4:00 PM to 8:00 PM ET on trading days, immediately after the regular session closes. Not every broker offers the full window, and liquidity thins sharply after about 6:30 PM ET.
