Gartner (IT) is trading at $179.33 after hours, down $0.26 (0.14%) from its regular-session close of $179.59.
IT 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.
After-hours trading in IT 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.
An after-hours move that carries into the next session becomes an opening gap, and IT's gap history is the best guide to what happens next: 50% of IT gap-ups have fully filled, and 50% 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.
IT is expected to report earnings around Nov 3, 2026 before the open (estimated), with an estimated EPS of $2.86. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
