The Pre-Market Data page is available for U.S. stocks. Pre-market hours run from approximately 4:00am ET and finishes at 9:30am ET.
The data displayed on this page is a minimum 15-minutes delayed and only updated during the pre-market session. As a result, pre-market data is not ready and available until approximately 4:20am ET.
The overview page shows the top Pre-Market Volume Leaders, Pre-Market Percent Advances and Declines, and Pre-Market Gap Ups and Gap Downs.
Earnings: Stocks whose Next Earnings Date falls within the next 7 days are highlighted with an "E" in the "Earnings" column. Hovering over the "E" will display the next earnings date and expected release time. Upcoming earnings may play a part in pre- and post-market trading.
What's Included
To qualify for inclusion on this page, Barchart lists common stocks with a price above $2, and a volume above 1,000. Premier Members can screen on all pre-market equities through the Stock Screener.
Pre-Market data is based on Form-T trades, which are considered a regular equities trade but made outside of normal trading hours. This excludes odd-lot trades which are trades made with less than 100 shares.
While odd-lots will count towards the daily volume, the 100 shares minimum rule is required by FINRA to constitute a regular trade and to be considered for the consolidated open, high, low and last price. During pre-market hours, Barchart has found odd-lot trades can distort the current price of a security especially when few shares traded.
