Why is KOP moving after hours?

KOP is up 0.03% 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 KOP after-hours trading start and end?

After-hours trading in KOP 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.

When does KOP report earnings?

KOP is expected to report earnings around Nov 6, 2026 before the open (estimated), with an estimated EPS of $1.32. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
