Nasdaq moves to make trading nearly 24 hours. Why some on Wall Street say that's a bad idea

Nasdaq is proposing to extend trading hours for US equities to nearly 24/7, aiming to improve market access for international investors and potentially capture more trading volume. However, some Wall Street participants are concerned about the implications for market liquidity during off-peak hours, the potential for increased volatility and algorithmic trading dominance, and the impact on work-life balance for traders and market infrastructure staff.
