Momentum is gathering behind the concept of 24-hour stock trading, raising alarms among industry professionals. Wall Street is particularly concerned about the implications of overnight trading, which is set to include pink sheet names starting in July 2024. The amateur-investing revolution, which has gained traction since the pandemic, is significantly contributing to this boom in overnight trading. Some experts warn that the continuous trading environment could lead to increased market volatility and potential financial losses for inexperienced traders. Notable stocks involved include $HOOD and $IBKR.
