Jasper Therapeutics (JSPR) is trading at $0.67 after hours, up $0.04 (6.51%) from its regular-session close of $0.63.
JSPR is up 6.51% 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 JSPR 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.
JSPR is expected to report earnings around Nov 9, 2026 (estimated), with an estimated EPS of $-0.19. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
