24-Hour Stock Trading Is Booming – and Wall Street Is Rattled

Wall Street is experiencing unease due to the increasing popularity of 24-hour stock trading among retail investors. This trend, fueled by the amateur-investing revolution seen in US markets since the pandemic, is particularly evident on platforms like Robinhood Markets Inc. and Interactive Brokers Group Inc. These platforms now allow the trading of American shares around the clock, five days a week. Concerns are rising among professionals about the potential risks associated with trading outside of traditional market hours. The shift towards continuous trading reflects a broader trend in the financial industry, where accessibility and flexibility for retail investors are becoming more prevalent. This development highlights the evolving landscape of stock trading and the challenges it poses for established market players.
