Stock market exchanges have standard hours during which most investors will trade: 9:30 a.m. ET to 4:00 p.m. ET. Extended Hours is the term used for times outside of a typical trading day when market activity might take place.

Share price during extended hours

A stock’s share price may move even when its listing exchange is closed due to Extended Hours trading. Some brokerage exchanges provide the ability to trade during after hours, and the resulting buying and selling activity could impact share price.

Some investors trade during the pre-market or after-hours sessions in response to breaking news, earnings reports, and other key information that may be made publicly available after the standard trading day has ended. For example, public companies will issue press releases and data surrounding their earnings either before the market opens or after it closes. Companies may also disclose things like acquisitions, leadership changes, and other major announcements in the pre-market or after-market hours.
