$QQQ ETH spreads wider than RTH spreads

US Stock Market pre-market and post-market bid-ask spreads are different than regular trading hours

Hours and Market Data on The US Stock Markets

Regular Trading Hours (RTH) in the US Stock Market is 9:30 a.m. to 4:00 p.m. Eastern Time. Trading can happen in the Pre-market hours (4:00 a.m. to 9:30 a.m. ET) and in the After Hours (post) market (4:00 p.m. to 8:00).

The pre-market and post-market are sometimes called Extended Trading Hours (ETH).

ETH markets do not behave the same as the RT sometimes called after-hours trading. To illustrate this here are a few graphs that show the spread over time for some of the QQQ, one of the most popular trading symbols in both RTH and ETH.

The following chart clearly shows that the average bid-ask spread during each minute bar varies widely in ETH.

  • The blue highlights are the pre-market hours.
  • The yellow highlights are RTH.
  • The green highlights are the post-market hours.
