Breaking Down the SET Trading Schedule
When is the Stock Exchange of Thailand open for trading?
The Stock Exchange of Thailand is open Monday through Friday from 10:00am to 12:30pm and 2:30pm to 4:30pm Indochina Time (GMT+07:00).
Does the Stock Exchange of Thailand close for Lunch?
Yes, the Stock Exchange of Thailand does close for lunch.
Many markets in Asia and a few markets in the Middle East close for lunch. Markets in most of the rest of the world do not close for lunch. Our market countdown and the TradingHours.com API both take lunch breaks into account.
There is typically less liquidity during the middle of the day. Most trading happens near the beginning and end of the day. Having a shorter trading window can help to make markets more efficient by increasing liquidity and reducing spreads.
Is the Stock Exchange of Thailand on Saturday or Sunday?
No, the Stock Exchange of Thailand is not open on weekends.
The Stock Exchange of Thailand is open for trading Monday-Friday. Stock Exchanges in America, Europe, and Asia follow the typical Monday to Friday schedule. However, in the Middle East the work week typically runs from Sunday through Thursday.
How long is the Stock Exchange of Thailand open for?
The Stock Exchange of Thailand is open for a total of 4 hours 30 minutes per day. Most markets are open 5 to 7 hours per day. Smaller markets tend to be open for short periods.
A shorter trading session compresses all trading activity into a smaller time period which leads to increased liquidity, smaller spreads, and more efficient markets. Shorter trading sessions can also lead to less volatility. Material news during trading hours can result in price volatility. With a smaller trading period, more news will happen outside regular trading hours which gives investors more time to digest information and can prevent rushed trading decisions.
Does the Stock Exchange of Thailand have After-Hours Trading?
Yes, the Stock Exchange of Thailand does have extended hours trading. There is no Pre-Trading Session. The Post-Trading Session is from 4:40pm to 5:00pm.
Shares can always be traded on the Stock Exchange of Thailand during regular trading hours (listed above).
Extended Trading Hours are sessions before and after the official trading session during which trading can be conducted electronically. Pre-market trading and after-hours trading generally have less volume than during the regular trading hours and may have different trading rules.
There is limited liquidity during extended hours which can cause increased volatility, larger spreads and greater price uncertainty. Earnings reports and other significant news are typically announced after regular trading hours end. This can lead to major price swings in after-hours markets.
