Want to invest in Hong Kong stocks, but often feel confused by terms like “board lot” and “odd lots”? Not sure how many shares are in one board lot, and worried about how to handle the odd lots you hold? Many beginner investors encounter this confusion when first entering the Hong Kong stock market. This article will start from scratch, explaining in detail the definition and origin of a “board lot”, teaching you how to calculate entry cost, and providing the most practical methods for handling odd lots, helping you take your first step into Hong Kong stock investing with ease.
In the Hong Kong stock market, the minimum trading unit is not “one share”, but a “board lot”. This seemingly simple concept is the first hurdle every beginner investor must overcome. Understanding how a “board lot” works is the foundation for developing trading strategies and managing capital.
The Hong Kong stock market uses “board lots” as the basic trading unit mainly due to historical traditions and considerations of trading efficiency. In the early days, before computer systems were widely used, grouping shares into fixed “board lots” for trading made manual processing and settlement much more efficient and reduced the chances of errors.
This is significantly different from other major markets:
The “board lot” system in Hong Kong is more unique, as the number of shares per lot can vary completely between different stocks, which is something beginners need to pay special attention to.
The number of shares in “one board lot” in Hong Kong is determined by the listed company itself and declared to the Hong Kong Exchange at the time of listing. Therefore, the number of shares per lot can range from 100 shares to hundreds of thousands of shares. This design aims to keep the “entry cost” (the minimum investment amount) for each lot at a level that is generally acceptable to the public (usually a few thousand Hong Kong dollars).
Here are some examples of popular Hong Kong stocks:
|
Stock Name (Ticker) |
Number of Shares per Board Lot | Assumed Share Price (HKD) | Minimum Entry Cost (HKD, Excluding Fees) |
| Tencent Holdings (00700) | 100 Shares | 380 | 38,000 |
| HSBC Holdings (00005) | 400 Shares | 68 | 27,200 |
| Tracker Fund of Hong Kong (02800) | 500 Shares | 18 | 9,000 |
| BYD Company (01211) | 500 Shares | 230 | 115,000 |
| Xiaomi Corporation (01810) | 200 Shares | 18 | 3,600 |

As shown in the table above, even well-known companies can have very different Hong Kong stock trading units. Therefore, before planning to buy any Hong Kong stock, your first task is to check its number of shares per board lot.

When the number of shares you hold is less than one “board lot”, these fractional shares are called “odd lots”. Although odd lots are not a major issue, if left unaddressed, they may affect the flexibility of your portfolio. Understanding how to handle odd lots is very important.
In most cases, odd lots are not actively purchased by investors but are generated passively. The main causes include:
When dealing with odd lots, there are two main strategies: sell them for cash or accumulate more shares to form a full board lot. Each has its own advantages and disadvantages, and you can choose based on your situation.
Strategy One: Sell Odd Lots
Strategy Two: Buy Additional Shares to Form a Board Lot
Most mainstream brokers support selling odd lots, and the process is usually straightforward:
Notes:
A: In most cases, yes. Due to much lower liquidity in the odd lot market, buyers (usually specialized odd lot dealers or the broker itself) require a discount to compensate for the risk and cost of aggregating odd lots into full board lots before reselling them. The discount varies by stock. The higher the liquidity and trading activity, the smaller the gap between odd lot prices and full board lot prices.
A: Some brokers offer this service, but not all. For brokers that support odd lot purchases, the interface is similar to selling odd lots. However, the purchase price of odd lots is usually higher than the market price. Before deciding to buy, you should calculate the cost and assess whether paying a premium to form a board lot is worthwhile.
A: No. While most major Hong Kong banks and brokerages support “selling” odd lots, fewer brokers support buying odd lots. Therefore, if you expect to frequently generate odd lots due to “scrip dividends” or other reasons, choosing a broker that offers comprehensive odd lot trading services is particularly important.
A: Not necessarily higher, but you need to pay attention to minimum charges. Odd lot trading still incurs standard fees such as commissions and platform fees. Since the total value of odd lot trades is usually small, if the broker has a “minimum commission”, the cost as a proportion of the trade value can be very high. For example, selling odd lots worth 100 HKD with a minimum commission of 50 HKD would make the trade highly uneconomical.
Understanding Hong Kong stock trading units is the foundation of successful investing. Fully grasping the concept of “how many shares are in one board lot” and learning how to check it allows you to accurately calculate investment costs and plan your capital. At the same time, being familiar with “how to handle odd lots” helps you manage your portfolio more efficiently and avoid issues caused by fragmented holdings. Investing is essentially a competition of knowledge and strategy. Apply what you have learned today in practice, choose a brokerage with comprehensive features and reasonable fees, and begin your journey in Hong Kong stock investing!
