Why is ATRA moving after hours?

ATRA is down 1.52% 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 ATRA after-hours trading start and end?

After-hours trading in ATRA 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 ATRA report earnings?

ATRA is expected to report earnings around Nov 11, 2026 (estimated), with an estimated EPS of $-0.13. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
