SEI Investments (SEIC) is trading at $106.96 after hours, up $0.03 (0.02%) from its regular-session close of $106.93.
SEIC is up 0.02% 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 SEIC 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.
An after-hours move that carries into the next session becomes an opening gap, and SEIC's gap history is the best guide to what happens next: 0% of SEIC gap-ups have fully filled, and 100% 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.
SEIC is expected to report earnings around Oct 28, 2026 after the close (estimated), with an estimated EPS of $1.58. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
