Pre-Market Movers: 07/31/2026

Want to know which stocks are already making big moves before the opening bell? The list below highlights the biggest pre-market movers today, giving investors a quick snapshot of stocks gaining or losing momentum before the opening bell.

Pre-market trading (4:00am to 9:30am Eastern Time) is when investors first respond to overnight earnings announcements, analyst rating changes, economic data releases, and breaking news. Stocks that experience the largest price changes during this session are often referred to as pre-market movers.

Because trading volume is typically lighter during pre-market hours, price swings can be sharper and volatility higher than during the regular session.

This tracker highlights the most notable pre-market movers on the NYSE and NASDAQ, showing the largest percentage gains and losses while filtering out companies with stock splits or unusually low trading volume. By monitoring which stocks are moving and researching the news behind those moves, investors can quickly identify potential opportunities and prepare for the day ahead.

Looking for stocks that moved after the previous trading session? View the After-Hours Movers list to see which companies experienced the biggest price changes after the market closed.

Porter flew 3,300 miles to investigate this system (Ad)

Porter Stansberry flew the Porter and Co. team 3,300 miles to Dublin to investigate a 17-year investing experiment called Project Prophet - and documented everything on film. Rooted in the laws of physics, this quantitative approach challenges conventional wealth-building wisdom. With 17 years of verified data behind it, Porter calls it unlike anything he has seen in nearly 30 years in the business.tc pixel

Frequently Asked Questions

Pre-market movers are stocks experiencing the largest price changes before the regular trading session begins. These movements typically occur during pre-market trading hours (4:00am to 9:30am) as investors react to overnight news, earnings releases, analyst rating changes, economic data releases, or other market developments.

Pre-market trading in the United States generally begins at 4:00am Eastern Time and continues until the market officially opens at 9:30am Eastern Time.

The MarketBeat Pre-Market Movers tracker identifies stocks listed on the NYSE and NASDAQ with the largest percentage price changes during the pre-market session. The list filters out companies with stock splits or unusually low trading volume to focus on meaningful price movements.

Stocks often move before the market opens as investors react to news released overnight or early in the morning. Common catalysts include:

  • Earnings reports
  • Analyst upgrades or downgrades
  • Economic data releases
  • Corporate announcements
  • Breaking news affecting specific companies or industries

These events can influence investor sentiment before the opening bell, sometimes causing stocks to gap higher or lower when the market opens.

Pre-market trading typically involves lower trading volume and fewer active participants than the regular market session. With less liquidity available, even relatively small buy or sell orders can move prices more dramatically.

As a result, price swings during pre-market trading can sometimes be larger than movements during normal market hours.

Pre-market trading typically involves fewer participants than the regular market session. Many institutional investors and market makers are less active before the opening bell, and some brokerages restrict certain order types. With fewer buyers and sellers available, trading volume is lower and price movements may be more volatile.

Pre-market price movements can provide early signals about investor sentiment, but they may not always reflect where a stock will trade once the regular session begins. Lower trading volume during extended hours can sometimes exaggerate price changes.

Many investors monitor pre-market movers to identify stocks attracting attention before the opening bell. Traders may use these lists to research news catalysts, spot potential breakout opportunities, or prepare trading strategies for the upcoming session.

Yes. Many online brokerages allow retail investors to trade during pre-market hours through electronic communication networks (ECNs). However, brokers may restrict order types or trading windows, and liquidity can vary significantly between stocks.

Investors can view pre-market stock prices through brokerage platforms, financial news websites, and market data services that display extended-hours trading activity and pre-market quotes. Many brokerage apps also show pre-market price changes alongside regular market prices.

Pre-market trading occurs before the regular market session (4:00am to 9:30am Eastern Time), while after-hours trading takes place after the market closes (4:00opm to 8:00pm Eastern Time). Both sessions allow investors to trade outside normal hours, but trading volume and liquidity are generally lower than during the regular session.
