Frequently Asked Questions
What is GLW's after-hours price?
Corning (GLW) is trading at $164.66 after hours, up $0.47 (0.28%) from its regular-session close of $164.19.
Why is GLW moving after hours?
GLW is up 0.28% 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 GLW after-hours trading start and end?
After-hours trading in GLW on the NYSE 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.
Will GLW's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and GLW's gap history is the best guide to what happens next: 86% of GLW gap-ups have fully filled, and 75% of gap-downs have filled over the past 5 years. Fill rates this high mean a large after-hours move is more often faded than extended.
When does GLW report earnings?
GLW is scheduled to report earnings on Oct 27, 2026 before the open (confirmed), with an estimated EPS of $0.88. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
