What is HKEX? A One-Minute Introduction to the Hong Kong Stock Exchange

The only official venue for Hong Kong stock trading is the Hong Kong Exchanges and Clearing Limited (HKEX), with stock code 0388.HK. As one of the top ten global exchanges and among the top three in Asia, HKEX has topped the global IPO fundraising charts multiple times over the past decade and is one of Asia’s most active capital markets.

HKEX’s parent company, Hong Kong Exchanges and Clearing Limited, manages multiple departments including the Hong Kong Stock Exchange, Hong Kong Futures Exchange, and clearing houses, covering comprehensive trading services such as stocks, options, and futures. It also controls international markets like the London Metal Exchange in the UK. As a joint-stock enterprise, HKEX is mainly owned by the Hong Kong Special Administrative Region and operates under the supervision of the Hong Kong Securities and Futures Commission.

A Quick Look at Hong Kong Stock Trading Hours

Additionally, Hong Kong stock trading has no price limit up or down. Trading units are measured in lots (number of shares per lot set by the company). Trading currencies include HKD, USD, and RMB. Settlement for sales is T+3 days. Fees vary by trading method (manual 0.5~1%, electronic 0.25~1%).

Detailed Explanation of Pre-market Session: How to Place Orders from 9:00~9:30

Before the official opening, there is a critical auction period from 9:00 to 9:30, divided into four sub-stages with different rules:

9:00~9:15 Order Entry Stage
Investors can input auction orders and limit auction orders, which can be freely modified or canceled. This is the open input phase, suitable for early positioning.

9:15~9:20 Pre-auction Matching Period
The system begins accepting auction orders and limit auction orders, but prices must be between the highest buy and lowest sell prices recorded at 9:15. Orders entered at this time cannot be canceled or modified. The market starts to stabilize.

9:20~9:22 Random Matching Period
Investors cannot input, modify, or cancel orders. The system automatically matches buy and sell orders. This is an automated, intervention-free phase.

9:22~9:30 Pause Period
All orders and trading activities are suspended until the morning trading officially begins.

The operation principle during this period is: the system calculates a reference equilibrium price based on investor input. Orders with prices better than this reference are automatically matched. If no reference price can be calculated, no automatic matching occurs. This time can be used for early analysis of Hong Kong stocks and to identify trading opportunities.

Detailed Explanation of After-hours Session: How the Random Closing Process from 16:00~16:10 Works

The after-hours auction process is the reverse of the pre-market, also divided into four phases:

16:00~16:01 Reference Price Calculation
The exchange calculates and announces the reference price based on trading data from the last minute of the continuous trading session (afternoon session).

16:01~16:06 Order Input Phase
Investors can input buy and sell orders, with prices within 5% above or below the reference price. Orders can be canceled or modified, offering higher flexibility.

16:06~16:08 Non-cancellable Phase
Investors can only place orders; cancellations or modifications are not allowed. The market begins to lock in, preventing last-minute changes.

16:08~16:10 Random Closing Phase
Investors can still place orders but cannot cancel or modify. The system randomly chooses a moment within these two minutes to close the market, automatically determining the closing price based on the highest volume of matched orders. All valid orders at that price are executed.

Hong Kong Stock Market Holidays in 2025

Besides weekends, HKEX also closes on specific holidays. The full holiday schedule for 2025 is as follows; investors should plan ahead:

Special Time Arrangement Reminders:

• Weekdays are Monday to Friday; weekends are closed as usual.
• On Christmas Eve, New Year’s Eve, and Lunar New Year’s Eve, there is no afternoon trading.
• During half-day trading days, closing auction starts at 12:00, with random close between 12:08~12:10.
• If there is no morning trading on a given day, there will be no continuation trading.

Key Points for Operating During Hong Kong Stock Trading Hours

Trading System and Time Coordination

Hong Kong stocks operate under a T+0 trading system, meaning you can buy and sell on the same day, but settlement is T+3. During the morning and afternoon sessions, investors can choose long-term holdings of blue-chip stocks based on fundamental analysis or engage in intraday short-term trading using technical analysis.

A notable feature is the support for short selling. If you are bearish on a stock, you can borrow shares from your broker and sell them in the secondary market. When the price drops, buy back and return the shares, earning the price difference. This is a unique advantage of Hong Kong stocks compared to some other markets.

Diversified Trading Options

Hong Kong stock trading is not limited to the HKEX spot market; off-market trading is also available. Besides direct stock purchases, investors can choose funds, ETFs, options, futures, or CFDs.

Among these, CFDs are particularly popular due to their flexibility. CFDs are margin trading instruments offering leverage from 1 to 200 times, allowing trading of multiple times or even hundreds of times the nominal amount with a deposit. This enables small capital to control large positions. Compared to margin financing on HKEX, CFDs support two-way trading and short selling without the need for securities borrowing, just requiring margin. However, leverage amplifies both gains and risks, so caution is advised.

Quick Checklist

Before trading Hong Kong stocks, ensure you have confirmed:

• ✓ Is today a trading day for HKEX (excluding holidays)?
• ✓ Which trading session are you in now (pre-market/morning/afternoon/after-hours)?
• ✓ Is the current session allowing the order operations you plan?
• ✓ If it’s a half-day trading day, is the afternoon session already closed?

Stock trading is not easy; understanding the Hong Kong trading hours is just the first step. Successful investors need to develop strategies based on trading sessions and stay updated with financial calendars and real-time market news to plan their trades effectively.

Regularly check the official HKEX website for the latest schedule to ensure your trading plans are always aligned with current rules.
