Premarket trading is the trading activity that occurs before the regular market session. It usually starts at **4:00 a.m.** and ends at **9:30 a.m.** Eastern Time (ET) in the US. During this time, traders can place orders to buy or sell stocks at the current market price. The pre-market quotes for relevant stock market futures (e.g., Dow Jones Futures, Nasdaq Futures, and S&P 500 Futures) and world markets indices, commodities, and currencies can be found on websites such as **Markets Insider**.

Pre-market activity indicates important events that occurred or are happening in the stock market. The news could be relevant to a single stock, an industry, a sector or perhaps the entire economy. Notable pre-market activity usually manifests in large price changes or volume that significantly exceeds the normal range.

After-hours trading is also available for investors who want to trade outside of regular market hours. For after-hours details, use the after-hours quotes service.
