OPK is down 1.92% 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 OPK 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.
OPK is expected to report earnings around Nov 4, 2026 after the close (estimated), with an estimated EPS of $-0.07. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
