Overview of Core Trading Sessions

Detailed Process of Pre-market Auction (9:00~9:30)

HKEX’s auction mechanism is divided into four phases:

9:00~9:15 Input Phase

• Investors can only input limit orders and auction limit orders
• Orders already entered can be modified or canceled at any time
• No matching occurs during this phase

9:15~9:20 Pre-matching Preparation Phase

• System accepts input of limit orders and auction limit orders
• Prices of new orders must be within the highest bid and lowest ask prices recorded at 9:15
• Orders entered cannot be canceled or modified further

9:20~9:22 Automatic Matching Phase

• Input, modification, or cancellation of orders is prohibited
• System calculates a reference equilibrium price and performs random matching
• Orders that meet the criteria are automatically executed

9:22~9:30 Trading Pause Phase

• All buy/sell orders and trading activities are suspended
• Waiting for the start of the morning trading session

The key during the pre-market period is the calculation of the reference equilibrium price. If the system successfully computes this price, matching occurs automatically for qualifying orders; otherwise, no matching takes place. Traders familiar with this mechanism can find early entry opportunities during the auction.

Detailed Process of Post-market Auction (16:00~16:10)

The operation logic of the post-market auction is opposite to that of the pre-market, divided into four phases:

16:00~16:01 Reference Price Calculation

• HKEX calculates a reference price based on trading data from the last minute of continuous trading
• The system announces this reference price for investor reference

16:01~16:06 Free Input Phase

• Investors can input new buy/sell orders
• Existing orders can be canceled or modified at any time
• Order prices should be within ±5% of the reference price

16:06~16:08 Modification Restriction Phase

• Investors can only place orders; cancellations or modifications are not allowed
• This transitional phase prepares for random closing

16:08~16:10 Random Closing Phase

• Investors can still place orders but cannot cancel or modify
• The system randomly selects a closing time within these two minutes
• The system automatically determines the final closing price based on the highest trading volume
• All qualifying orders will be executed

Strategic Application of Hong Kong Stock Trading Hours

Time Slot Selection and Trading Strategies

Different trading sessions suit different investment strategies. The continuous trading sessions in the morning and afternoon are suitable for fundamental analysis, selecting quality blue-chip stocks for long-term holdings; technical analysis can also be used to identify short-term trading opportunities.

It’s important to note that Hong Kong stocks operate under a T+0 trading system, meaning stocks bought on the same day can be sold on the same day, but settlement occurs on T+3. Additionally, Hong Kong stocks support short selling; investors who believe a stock will decline in the future can borrow shares from brokers to sell in the secondary market, then buy back at a lower price to return the shares and profit from the price difference.

Diversified Trading Methods

Hong Kong stock trading is not limited to spot trading on HKEX; investors can also participate through various derivatives:

Funds and ETFs Achieve diversification and reduce risk associated with individual stocks.

Options and Futures Provide hedging and leverage tools, suitable for advanced investors.

CFD Contracts Compared to spot trading on HKEX, CFDs offer unique advantages. They provide leverage of 1-200 times, allowing control of a trading volume much larger than the margin deposited, enabling small capital to achieve large gains. They also support two-way trading and short selling without the need for borrowing shares, avoiding the procedures and leverage limits of HKEX’s securities borrowing. However, leverage amplifies both gains and risks.

Important Notices on Special Trading Arrangements

Weekday Schedule HKEX’s standard trading days are Monday to Friday, with weekends off. Investors should plan their trading activities accordingly.

Half-day Trading Special Rules If a trading day is designated as a half-day, the closing auction session will start at 12:00, with a random close between 12:08 and 12:10. No morning or afternoon trading sessions will occur that day.

Continuing Trading Notes

• If there is no morning trading on a given day, no continuation of morning trading occurs that day
• Exceptions may be made if stipulated by the board of directors
