After-hours trading some times abbreviated as AHT refers to buying or selling securities outside of the standard trading hours. Each exchange has their own official trading hours. Pre-market trading is very similar to After-Market Trading. Both terms refer to trading stock outside of the normal day session. Pre-market trading is in the morning before markets open while after-hours trading is in the evening. In the context of extended-hours trading, the normal trading hours are referred to as the day session.

Higher volatility also results due to the low trading volume compared to during the day session. Because there are fewer trades happening, you are more likely to experience large, unexpected price shifts than during normal trading hours.
