Trading in extended hours enables investors to react quickly to events that typically occur outside regular market hours, such as earnings reports. However, liquidity may be constrained during such Form T trading, resulting in wide bid-ask spreads. Form T trading is especially suited for overseas investors, since they may conduct the bulk of their U.S. trading when their markets are open but U.S. markets are closed.
