Factors Affecting Stock Market Opening Hours
Time Zones and Overlapping Markets
Global stock markets operate in different time zones. Some investors take advantage of overlapping hours, such as when the London and New York markets are open at the same time, increasing trading volume and liquidity.
Pre-Market and After-Hours Trading
Many stock exchanges allow trading outside regular hours. These extended sessions provide additional opportunities but come with lower liquidity and higher volatility.
Stock Market Holidays
Stock markets close on national holidays, which vary by country. Traders should check exchange calendars for holiday schedules to avoid unexpected closures.
