Half-Day Trading Rules for Hong Kong Stocks

Half-day trading in Hong Kong stocks occurs on specific dates such as Christmas Eve, New Year’s Eve, and Lunar New Year’s Eve, during which:

• Only the morning session is conducted
• No afternoon trading or continuation of the morning session

On these days, the trading process is adjusted as follows:

• Pre-market auction: 9:00~9:30
• Morning trading: 9:30~12:00
• Market close auction: open at 12:00, random close between 12:08~12:10

This means traders must complete all trading decisions by 12:00 noon, and no trading will occur in the afternoon.

Detailed Explanation of Pre-Open Period (9:00~9:30)

The pre-market auction at HKEX is divided into four detailed phases:

9:00am – 9:15am | Order Entry Period
Investors can only input limit orders and auction limit orders. Orders entered can be modified or canceled at any time.

9:15am – 9:20am | Order Matching Preparation
System accepts auction orders and auction limit orders, with prices within the highest bid and lowest ask recorded at 9:15am. Orders entered cannot be canceled or modified during this phase.

9:20am – 9:22am | Matching Period
Order entry, modification, or cancellation is prohibited. The system performs random matching and automatic pairing of buy and sell orders.

9:22am – 9:30am | Pause Period
All order activities are suspended, awaiting market open.

The reference price during this period is calculated based on the entered orders. Limit orders at or better than this reference price will be automatically matched during the matching phase. If the reference price cannot be determined, no automatic matching occurs.

Detailed Explanation of Post-Close Auction (16:00~16:10)

The closing auction mechanism is the reverse of the pre-open process, divided into four phases:

16:00~16:01 | Calculation and Announcement of Reference Price
HKEX calculates and announces the reference price based on the last minute of continuous trading data.

16:01~16:06 | Order Entry Period
Investors can input new orders, cancel, or modify existing ones. Prices must be within ±5% of the reference price.

16:06~16:08 | Cancellation Prohibition Period
Orders can only be placed; cancellations or modifications are not allowed.

16:08~16:10 | Random Close Period
Orders can still be placed but not canceled or modified. The system will randomly close the market within these two minutes, selecting the price with the highest trading volume as the closing price. All valid orders will be executed at this price.

Trading Strategies and Methods During HKEX Trading Hours

Choosing Reasonable Trading Strategies

HK stocks follow a T+0 trading system, but settlement occurs T+3. Different strategies can be employed during various trading periods:

Morning and Afternoon Sessions: Fundamental analysis can be used to select blue-chip stocks for long-term investment, or technical analysis for short-term trading. On half-day trading days, traders should complete major decisions during the morning session.

Pre-open and Post-close Auction Periods: Suitable for seeking breakout opportunities and liquidity concentration. Analyze HK market trends before open to find trading opportunities, and manage risk based on daily performance after close.

Short Selling: HK stocks support short selling. If bearish on a stock, borrow it from your broker, sell in the secondary market, and buy back at lower prices to profit from the difference.

Diversified Trading Methods

Besides direct stock purchases, HKEX offers various trading options:

Funds and ETFs: Passive investment tracking indices or specific strategies.

Options and Futures: Derivatives suitable for hedging or leverage needs.

Contracts for Difference (CFD): Leverage trading tools with 1-200x leverage, allowing trading of amounts many times the margin. Compared to direct HKEX trading, CFDs offer two-way trading and no need for securities borrowing when shorting, but leverage also amplifies risks.

Summary

Understanding HKEX trading hours is fundamental to successful trading. In 2025, special attention should be paid to half-day trading days, especially the three key dates (Lunar New Year’s Eve, Christmas Eve, New Year’s Eve), where all operations must be completed by 12:00 noon.
