RE: After hours?23 Sep 2021 22:29
time after the market closes when an investor can buy and sell securities outside regular trading hours. Both the New York Stock Exchange (NYSE) and the Nasdaq normally operate between 9:30 a.m. and 4:00 p.m. Eastern Time. Trades during the after-hours session can be completed anytime between 4:00 p.m. and 8:00 p.m. Eastern Standard Time.1?2?
In these extended trading sessions, electronic communication networks (ECNs) match potential buyers and sellers without using a traditional stock exchange. The trading volume during the after-hours trading session tends to be fairly thin. That's because there are usually very few active traders during this time period. This can change, though, with volume spiking if there's big economic news or something breaks about a company.
Just like volume, traders can expect wider spreads—the difference between the bid and ask prices—after the market closes
