Extended-hours trading

From Wikipedia, the free encyclopedia
Not to be confused with Late trading or Aftermarket (finance).

Extended-hours trading (or electronic trading hours, ETH) is stock trading that happens either before or after the trading day of a stock exchange, i.e., pre-market trading or after-hours trading.

After-hours trading is the name for buying and selling of securities when the major markets are closed.[1] Since 1985, the regular trading hours for major exchanges in the United States, such as the New York Stock Exchange and the Nasdaq stock market, have been from 9:30 a.m. to 4:00 p.m. Eastern Time (ET).[2] Pre-market trading occurs from 4:00 a.m. to 9:30 a.m. ET, although the majority of the volume and liquidity come to the pre-market at 8:00AM ET.[3][4] After-hours trading on a day with a normal session occurs from 4:00 p.m. to 8:00 p.m. ET.[4] Market makers and specialists generally do not participate in after-hours trading, which can limit liquidity.[5]

Trading outside regular hours is not a new phenomenon but used to be limited to high-net-worth investors and institutional investors like mutual funds.[6] The emergence of private trading systems, known as electronic communication networks (ECNs), has allowed individual investors to participate in after-hours trading.

Financial Industry Regulatory Authority (FINRA) members who voluntarily enter quotations during the after-hours session are required to comply with all applicable limit order protection and display rules (e.g., the Manning rule and the SEC order handling rules).[7]
