About pre-market stock movers

Pre-market movers are the stocks making the biggest moves before the 9:30 AM ET opening bell — pre-market trading runs from 4:00 AM ET. Because volumes are thinner than in the regular session, pre-market prices react fastest to overnight earnings, economic data, and company news, and they preview how a stock may open.

The list is split into gainers and losers so you can see both sides of the pre-market at a glance. Click any ticker for its full quote page, chart, and the news driving the move.

Frequently asked questions

What time is pre-market trading?

Pre-market trading on US exchanges runs from 4:00 AM to 9:30 AM ET, ahead of the regular session open.

Do pre-market moves predict how a stock will open?

They're a strong hint but not a guarantee. Pre-market volume is light, so prices can shift again once the full market opens and liquidity arrives.

Why are pre-market moves often larger?

Thinner pre-market volume means individual orders move prices more, so reactions to overnight news can look outsized compared with the regular session.

How often is this list updated?

Rankings are recalculated on a 60-second snapshot, and the prices shown refresh every few seconds while pre-market trading is open.
