Frequently Asked Questions
What is ISRG's after-hours price?
Intuitive Surgical (ISRG) is trading at $368.62 after hours, down $0.53 (0.14%) from its regular-session close of $369.15.
Why is ISRG moving after hours?
ISRG is down 0.14% 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 ISRG after-hours trading start and end?
After-hours trading in ISRG 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.
Will ISRG's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and ISRG's gap history is the best guide to what happens next: 0% of ISRG gap-ups have fully filled, and 80% 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 ISRG report earnings?
ISRG is scheduled to report earnings on Oct 20, 2026 after the close (confirmed), with an estimated EPS of $2.54. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
