Top Premarket Gainers Today (October 17, 2026)

The strongest movers by percentage change for the current market session. For the full two-sided view including losers, use Premarket Movers.

What Are Premarket Gainers?

Premarket gainers are stocks that show the largest positive price movements during the pre-market trading session, which runs from 4:00 AM to 9:30 AM Eastern Time before the regular market opens. These early moves often signal important developments — earnings beats, analyst upgrades, sector momentum, or breaking news that shifts investor sentiment.

Tracking premarket gainers gives traders a head start on the trading day. Stocks that gap up significantly in pre-market often continue their momentum into the regular session, though low pre-market volume can also lead to reversals. Use the Z-Score and relative volume columns on our Movers page to distinguish genuine momentum from noise.
