OTC Markets U.S. Extended Hours Trading
Stocks can always be traded on the OTC Markets U.S. during regular trading hours but there are also extended hours whereas trades may be made. There is significantly less trading volume during extended hours. Lower volume results is a larger spread, bigger price jumps, more volatility, and more risk. Extended Hours Trading allows investors to act quickly on information that comes out after markets closed.
In the past, only large institutional investors could participate in Extended Hours Trading. Due to the emergence of electronic trading platforms, individual investors are now able to trade during extended hours as well. Depending upon your broker, you can usually choose to execute trades during pre- or after-hours or only during regular trading.
