Frequently Asked Questions
What is AMSC's after-hours price?
American Superconductor (AMSC) is trading at $28.02 after hours, up $0.21 (0.76%) from its regular-session close of $27.81.
Why is AMSC moving after hours?
AMSC is up 0.76% 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 AMSC after-hours trading start and end?
After-hours trading in AMSC 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.
When does AMSC report earnings?
AMSC is expected to report earnings around Nov 4, 2026 before the open (estimated), with an estimated EPS of $0.18. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
