Why is COLB moving after hours?
COLB is down 0.97% 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 COLB after-hours trading start and end?
After-hours trading in COLB 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.
When does COLB report earnings?
COLB is expected to report earnings around Oct 29, 2026 after the close (estimated), with an estimated EPS of $0.77. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
