Frequently Asked Questions

What is STX's after-hours price?

STX is trading at $945.84 after hours, up $96.85 (11.41%) from its regular-session close of $848.99.

Why is STX moving after hours?

STX is up 11.41% 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 STX after-hours trading start and end?

After-hours trading in STX 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.

Will STX's after-hours move hold at the open?

An after-hours move that carries into the next session becomes an opening gap, and STX's gap history is the best guide to what happens next: 64% of STX gap-ups have fully filled, and 85% of gap-downs have filled over the past 5 years. Fill rates this high mean a large after-hours move is more often faded than extended.

When does STX report earnings?

STX is scheduled to report earnings on Oct 27, 2026 after the close (confirmed), with an estimated EPS of $7.30. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
