CarMax (KMX) is trading at $54.94 after hours, up $0.02 (0.04%) from its regular-session close of $54.92.
KMX is up 0.04% 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 KMX 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.
KMX is expected to report earnings around Dec 17, 2026 before the open (estimated), with an estimated EPS of $0.47. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
