Key Questions Answered
US equity exchanges such as Nasdaq, NYSE Arca, 24X National Exchange, and Cboe EDGX plan to launch an overnight session from 9 p.m. to 4 a.m. in New York starting on December 6, moving toward around-the-clock trading.
The expansion seeks to capture growing demand from foreign investors and compete directly with crypto and prediction markets that have upended traditional Wall Street operating hours.
Institutional investors are primarily worried about market quality during extended hours, pointing to potential risks like lower trading volumes, thinner liquidity, wider bid-ask spreads, and increased volatility.
