Hong Kong Stock Order Types: 7 Strategies for Smart Investing

As an experienced quantitative trading professional, I am often asked, “How do I choose the best type of order to place in the Hong Kong stock market?” This question may seem simple, but it actually contains the mystery of trading success. Today, let's unravel the mystery of Hong Kong stock order types to help you navigate through this market full of opportunities.

Ⅰ. Limit Order: The Art of Precise Control

Limit Order is one of the most common types of orders in the Hong Kong stock market, which allows investors to specify a specific price for trading.

Features:

• When buying, the transaction will only be executed when the market price is lower than or equal to the specified price
• When selling, the order will only be filled when the market price is higher than or equal to the specified price.
• It protects the investor from price fluctuations.

Case Study:

Suppose the current market price of Tencent Holdings (700.HK) is HK$500 and you wish to buy 100 shares at HK$498. You can place a limit order specifying a price of HK$498. Your order will only be executed if the stock price falls to HK$498 or below.

Use the strategy:

• Ideal for investors who have a clear expectation of the target price
• Protect yourself from being “trapped” in a volatile market.
• May miss out on fast rises or falls

Ⅱ. Market Order: The Speed Option

The Market Order is the best option for immediate execution. It does not specify a price, but rather executes the trade immediately at the best current price.

Features:

• Guaranteed transaction, but not guaranteed price
• Ideal for less price sensitive trades that require immediate execution.
• Best used in highly liquid stocks.

Case study:

Suppose you urgently need to sell your shares of HSBC Holdings (5.HK). At this point, you can choose a Market Order, which will immediately execute the transaction at the highest bid price in the current market.

Use Strategy:

• Ideal for quick market entry and exit during major news releases
• Less risky to use in highly liquid stocks.
• Avoid highly volatile and illiquid stocks.

Ⅲ. At-auction Order: The smart choice for opening and closing the market.

The At-auction Order is specifically designed to participate in the pre-opening and closing bidding sessions of the Hong Kong stock market.

Features:

• No specified price, trading at the final equilibrium price
• Participate in the price discovery process
• Ideal for block trades or investors who are sensitive to opening and closing prices.

Case study:

If you want to buy Alibaba (9988.HK) shares at the opening price, you can enter your bid order during the pre-opening bidding session (9:00-9:30). Your order will participate in the price formation process and will be filled at the firm opening price when the market opens.

Use the strategy:

• Take advantage of liquidity concentration during the bidding session
• Avoid missing important opening or closing prices.
• Ideal for executing closing price-based investment strategies

Ⅳ. Enhanced Limit Order (ELO): represents flexibility.

Enhanced Limit Order is a unique order type in the Hong Kong stock market which combines the features of Limit Order and Market Order.

Features:

• Can be filled at specified price or better
• The unfilled portion is converted to a limit order
• Provides additional price protection

Case study:

Suppose China Mobile (941.HK) is currently quoted at HK$50 and you wish to buy at HK$50.5 or lower. Using an Enhanced Limit Order, if there is a sell order in the market at HK$50.5 or lower, your order will be filled immediately; if not, the remainder will be retained as a limit order at HK$50.5.

Use the strategy:

• Used when the price is volatile but you don't want to miss the opportunity
• Combines the advantages of immediate execution and price protection
• Ideal for investors who wish to have the flexibility to trade around a specific price level

Ⅴ. Special Limit Order: All or Nothing

A Special Limit Order is an “all or nothing” order type that is either filled or canceled.

Features:

• Only executed if the entire order quantity can be filled at the specified price or better.
• If the entire order cannot be filled, the entire order will be canceled.
• Ideal for transactions that require precise control over the quantity to be filled.

Case study:

Let's say you want to buy 1,000 shares of Ping An (2318.HK) and only execute the trade if you can buy them all at once. Using a special limit order, you can ensure that you either buy all 1000 shares or none at all.

Use the strategy:

• Ideal for large trades or for investment strategies that require precise control of positions.
• Avoid the extra costs and risks associated with partial trades
• Works better with more liquid stocks.

Ⅵ. Odd Lot Order: The Savior of Smaller Investments

Odd Lot Order allows investors to trade a number of shares less than one lot (usually 100 shares).

Features:

• Allows trading of less than one lot of shares
• Often illiquid and may be subject to large bid/ask spreads.
• Ideal for small investments or adjusting the number of positions held

Case study:

Suppose you hold 90 shares of HSBC Holdings (5.HK) and the standard trading unit is 100 shares. You can use a fractional order to sell the 90 shares instead of buying 10 shares to make up one lot.

Use the strategy:

• Suitable for beginners or investors with limited capital to try out high priced stocks
• Used to adjust the portfolio to achieve a precise number of holdings.
• Note that you may face higher transaction costs and wider bid/ask spreads.

Ⅶ. Short Sell Order with Borrowed Securities: a tool for advanced players

This is an order type that allows an investor to sell shares without owning them, but requires prior borrowing of securities.

Features:

• Allows investors to take profits in anticipation of a fall in share price
• Requires payment of fees and interest on borrowed securities
• Higher risk, suitable for experienced investors

Case study:

If you expect the share price of Xiaomi Group (1810.HK) to fall, you can borrow shares of Xiaomi and sell them. If the stock price really falls, you can buy back the shares at a low price, return them to the lender and gain the difference in price.

Use strategy:

• For hedging against other investment risks
• To take profits when you are bearish on a stock
• Precise risk management is required as the potential losses can be significant.
