Trading Hours

The trading hours of the Hong Kong stock market are divided into three main sessions, each with distinct functions and characteristics. Below is the detailed time breakdown:

During the pre-opening session, investors can submit buy and sell orders, but trades are not executed immediately. The continuous trading session is the most active period, with all trades completed during this time. The closing auction session is used to determine the closing price. Familiarizing yourself with these sessions helps you better organize your trading plan and avoid missing important market opportunities.

T+0 Trading System and T+2 Settlement Rules

The Hong Kong stock market adopts a T+0 trading system, which means you can buy and sell the same stock multiple times within the same day, offering high flexibility. However, the settlement follows a T+2 model, meaning funds and stocks are settled on the second business day after the trade.

This system design helps enhance market liquidity while reducing settlement risks. For beginners, understanding this is crucial, as it directly affects your capital flow and investment strategy. For example, if you trade on a Friday, settlement will be completed on the following Tuesday. Therefore, you need to consider this time gap when planning your fund usage.

No Price Limit and Volatility Control Mechanism

The Hong Kong stock market has no price limit, allowing stock prices to fluctuate significantly within a single day. This feature provides investors with more profit opportunities but also increases risks. To balance market stability, the Hong Kong Stock Exchange implements a volatility control mechanism for 81 major constituent stocks of the Hang Seng Index and Hang Seng China Enterprises Index.

When a stock price fluctuates by more than 10% within 5 minutes, a 5-minute cooling-off period is triggered. During this period, trading is restricted to a ±10% range of the reference price. This mechanism effectively prevents panic selling or irrational buying due to excessive market volatility.

Additionally, research shows that herd behavior significantly increases market volatility, potentially leading to price bubbles or panic selling. Non-herd behavior, however, can stabilize the market during extreme sentiment, reducing further price declines. These rules and mechanisms provide investors with a safer trading environment.

Minimum Trading Unit and Price Movement Rules

In the Hong Kong stock market, each stock has a minimum trading unit, which is an important rule you need to understand when trading. The minimum trading unit refers to the smallest number of shares you must buy or sell in a single transaction. For example, some stocks have a minimum trading unit of 100 shares, meaning you cannot buy 50 or 75 shares; you must purchase at least 100 shares or multiples thereof (e.g., 200, 300 shares).

How to Check the Minimum Trading Unit?

You can check a stock’s minimum trading unit through the following methods:

• Hong Kong Stock Exchange Website: Visit the official Hong Kong Stock Exchange website, search for the stock code, and view its minimum trading unit.
• Trading Platform: Most trading platforms display the minimum trading unit on the order placement interface for quick reference.
• Broker Customer Service: If you’re unsure about a stock’s minimum trading unit, you can contact your broker’s customer service for clarification.

Tip: When selecting stocks, ensure you have sufficient funds to purchase the minimum trading unit to avoid being unable to complete a trade due to insufficient capital.

Price Movement Rules

The price movement rules in the Hong Kong stock market are based on the “minimum price movement unit.” This means that each stock price change must adhere to a specific increment. For example, for stocks priced between 0.25 USD and 0.50 USD, the minimum price movement unit is 0.001 USD; for stocks priced above 10 USD, the minimum price movement unit is 0.01 USD.

Below is a simple table to help you understand the minimum price movement units for different price ranges:

Why Are These Rules Important?

The minimum trading unit and price movement rules directly impact your trading plan and costs. For example, if you plan to buy a stock priced at 50 USD with a minimum trading unit of 100 shares, you need to prepare at least 5,000 USD. Additionally, understanding the minimum price movement unit helps you set buy or sell prices more accurately, avoiding missed trading opportunities due to improper price settings.

Note: Before trading, carefully check the stock’s minimum trading unit and price movement rules to better manage funds and improve trading efficiency.

3. Complete Identity Verification
   The broker will require identity verification. Some brokers support online verification, where you upload documents and complete a video call. Other brokers may require you to visit a branch in person.
4. Await Review
   After submitting the application, the broker will conduct a review, which typically takes 1 to 3 business days. Once approved, you will receive your account number and login information.

Tip: When choosing a broker, ensure it supports the trading tools and features you commonly use, such as mobile apps or web-based trading platforms.

Funding the Account and Choosing a Trading Platform

After opening the account, you need to deposit funds into the account and familiarize yourself with the trading platform’s operations.

1. Deposit Funds
   You can deposit funds into your trading account via bank transfer or check deposit. Some brokers support deposits in multiple currencies, but it’s recommended to use USD or HKD, as these are the primary currencies for Hong Kong stock trading.
   • Bank Transfer: Use your bank’s online banking service and enter the broker’s provided recipient account information to complete the transfer.
   • Check Deposit: Visit the broker’s branch, fill out a check, and submit the deposit application.
2. Choose a Trading Platform
   Most brokers offer multiple trading platforms, including mobile apps, web-based versions, and desktop software. You need to familiarize yourself with the platform’s basic functions, such as viewing stock prices, placing orders, and checking transaction records.
   • Mobile App: Suitable for trading on the go.
   • Web-Based Platform: Suitable for computer-based operations with more comprehensive features.
   • Desktop Software: Suitable for professional investors, offering advanced analytical tools.

Note: When depositing funds, ensure the source of funds complies with the broker’s regulations to avoid delays due to compliance issues.

Placing Orders

After completing the account opening and funding, you can start trading Hong Kong stocks. Below are the basic steps for placing orders:

1. Select a Stock
   Search for the stock code of interest on the trading platform, check its real-time price and trading volume. You can choose stocks based on market analysis or personal investment strategies.
2. Set Trading Instructions
   Hong Kong stock trading supports multiple order types, including limit orders, market orders, and stop-loss orders.
   • Limit Order: Set a fixed price, and the trade will only execute when the market price reaches that level.
   • Market Order: Execute the trade immediately at the current market price, suitable for investors seeking quick execution.
   • Stop-Loss Order: Set a trigger price to control risks.
3. Confirm the Trade
   After entering the stock quantity and price, carefully review the trading instructions and click the “Confirm” button. Once the trade is completed, you can view the details in the transaction records.
4. Monitor Trading Status
   After placing an order, closely monitor the trading status. If market prices fluctuate significantly, you may need to adjust your trading strategy.

Suggestion: Beginners should start with small trades to gradually familiarize themselves with market operations and avoid losses due to operational errors.

Monitoring the Portfolio and Adjusting Strategies

Monitoring your investment portfolio is a critical aspect of successful investing. After trading Hong Kong stocks, regularly reviewing your portfolio’s performance can help you identify issues and adjust strategies in a timely manner. This not only improves capital efficiency but also reduces risks.

How to Effectively Monitor Your Portfolio?

1. Regularly Check Investment Performance
   Review your portfolio’s returns and risk levels monthly or quarterly. This frequency suits busy investors as it requires less system stability. You can use the trading platform’s reporting functions to quickly assess each stock’s performance.
2. Stay Informed About Market Changes
   The Hong Kong stock market is highly volatile, with stock prices potentially fluctuating rapidly due to policies, economic data, or company news. You need to closely follow market news, especially information related to the stocks you hold. This helps you respond quickly to abnormal market fluctuations.
3. Analyze Trading Data
   By analyzing trading frequency and average holding period, you can evaluate capital efficiency. Excessive trading frequency may lead to overtrading, increasing fees and slippage costs, which can affect strategy performance. Conversely, overly long holding periods may cause you to miss other investment opportunities.

Tip: Use the trading platform’s data analysis tools to gain a more intuitive understanding of your portfolio’s performance and identify areas for improvement.

How to Adjust Investment Strategies?

1. Reallocate Assets
   If certain stocks underperform, consider reducing their allocation and redirecting funds to stocks with greater potential. Such adjustments can optimize your portfolio and improve overall returns.
2. Consider Trading Costs
   When adjusting strategies, always account for the impact of trading costs. Fees and slippage significantly affect the net profits of high-frequency trading strategies. If your strategy involves frequent trading, choose a broker with lower fees.
3. Set Stop-Loss and Take-Profit Points
   Setting clear stop-loss and take-profit points for each stock helps you stay calm during market volatility. When the stock price reaches the set price, the system automatically executes the trade, avoiding losses due to emotional decisions.
4. Regularly Backtest Strategies
   During strategy development and backtesting, review past trading records to analyze which strategies are effective and which need improvement. This helps you make more informed decisions in future trades.

Examples and Data Support

• Monthly or quarterly portfolio rebalancing suits busy investors as it requires lower system stability.
• Excessive trading frequency can affect capital efficiency, potentially leading to overtrading and reduced strategy performance.
• In strategy development and backtesting, trading costs (such as fees and slippage) significantly impact the net profits of high-frequency trading strategies.

Note: When adjusting strategies, ensure each decision is supported by data to avoid impacting investment performance due to subjective judgments.

By monitoring your portfolio and adjusting strategies, you can better navigate market changes and improve investment returns. Whether you’re a beginner or an experienced investor, these methods can help you stay competitive in the Hong Kong stock market. If you’re still wondering “how to buy Hong Kong stocks,” start with small investments to gradually familiarize yourself with market operations.
