Key Takeaways
- Most Bursa-listed shares trade in standard board lots of 100 units.
- An odd lot is below 100 shares or leaves a quantity not divisible by 100.
- Odd-lot orders use a separate market where partial matching and price-time priority apply.
- Lower odd-lot liquidity can mean slower fills or a price that differs from the normal market.
- Compare trade value, broker charges, spread and available quantity before placing a small order.
A typical Bursa board lot contains 100 units. That standard defines how most listed shares are quoted and ordered, while smaller or non-divisible quantities are handled through the Odd Lot Market.
The rule is simple, but the cost of a trade still depends on the share price, available quantity and broker charges. This guide from Trade.com.my shows how to turn the 100-unit standard into practical order checks.
What a Board Lot Means
| Term | Meaning | Simple example |
|---|---|---|
| Unit | One share or security unit | 100 units = one typical board lot |
| Board lot | Standard trading quantity | 300 units = three board lots |
| Odd lot | Below 100 or not divisible by 100 | 350 units = three lots plus 50 odd-lot units |
A board lot is a standard quantity used for orders in the Normal Market. Bursa Malaysia states that shares are normally traded in board lots of 100 units. One unit is one share or security unit, not one lot.
Consider a holding of 350 shares. Three full board lots account for 300 shares; the remaining 50 form an odd lot. The shares are the same class of security, but the order route and available counterparties can differ.
Board lots should not be confused with physical share certificates. Malaysia’s market uses electronic records; the Trade.com.my guide to Bursa Malaysia certificates explained provides related background on the older certificate concept.
Standard Lot Sizes on Bursa
The 100-unit standard does not create one universal minimum in ringgit. The gross share value is the quoted price multiplied by the number of units. A RM0.50 share therefore has a gross one-lot value of RM50, while a RM10 share has a gross one-lot value of RM1,000.
A RM1.20 share has a gross one-lot value of RM120, and a RM3.00 share has a value of RM300. These are share values before brokerage and other applicable charges, not final order totals.
As a quick sense-check, review the broker’s estimated order cost before confirming a trade. For a lower-priced share, fixed or minimum charges can be large compared with the share value.
You do not need a specific amount of money to understand the rule. First confirm the security’s trading unit, then multiply price by quantity. The Malaysia stocks resources hub has more beginner guides for researching Bursa-listed shares.
How the Odd Lot Market Works
Bursa defines an odd lot as fewer than 100 shares or a quantity not divisible by 100. The Odd Lot Market allows partial matching, and orders follow price-time priority within the normal market price limit.
It uses the same published trading sessions as the Normal Market. Pre-opening begins at 8:30 am and 2:00 pm, while continuous trading begins at 9:00 am and 2:30 pm. Unmatched first-session day orders can carry forward to the second session.
Odd lots can arise after a bonus issue, share split or another corporate action. For example, an investor with 450 shares who sells 400 in the regular market is left with 50 shares to handle through the odd-lot route.
A broker’s interface may place the odd-lot option in a different menu. The practical process is to check the separate order book rather than copying the last price from the Normal Market.
- Open your broker’s separate odd-lot order option.
- Check the odd-lot bid, ask and quantity available.
- Enter a limit price and the exact number of shares.
- Review the estimated cost, fees and order validity.
- Submit the order and monitor any partial fill.
Costs and Liquidity Considerations
An odd-lot trade can have fewer available counterparties than a standard board-lot trade. That lower liquidity can produce a wider spread, slower execution or a partial fill. None of these outcomes is guaranteed, but they are worth checking.
Compare the bid and ask in both the regular and odd-lot order books when you need a reference. The last-traded price does not prove that your preferred quantity can match at that price. Use a limit price to control the worst price you are willing to accept.
Brokerage, clearing-related charges and other costs can make small trades inefficient. The verified research does not provide one universal fee schedule, so check the current estimate shown by your broker before submitting.
Inspect these five items before placing a small order:
- The current bid and ask in the correct order book
- The quantity available at your limit price
- The broker’s estimated charges for that trade size
- Whether a partial fill would still meet your goal
- The order’s validity and your plan for any remainder
Board Lot Examples in Ringgit
Suppose a share is quoted at RM0.80. One 100-unit board lot has a gross share value of RM80 before fees. A RM4.25 share has a one-lot value of RM425. The buying power required changes with price even though the lot size stays at 100.
Now consider 35 units at RM4.25. The gross share value is RM148.75. The calculation is valid, but execution still depends on an odd-lot seller being available at your limit price and on your broker supporting the order.
Another example starts with 450 shares. Selling 400 as four board lots leaves 50. Those 50 do not disappear or change ownership records; they remain in the holding until separately sold or otherwise affected.
Before confirming any order, calculate price × quantity, add the broker’s estimated charges, and inspect the correct order book. This three-part check prevents a simple 100-unit rule from hiding the real cost or execution risk.
Use the Bursa Board Lot Rule Before Every Order
The Bursa board lot rule gives you the starting quantity: usually 100 units. Then check the quoted price, the correct order book, available depth and the broker’s full cost estimate.
For an odd lot, plan for a possible partial fill and verify the platform’s process. The quantity rule is fixed, but the decision still depends on price, liquidity, cost and your own investment plan.
What is one board lot on Bursa Malaysia?
One standard board lot is normally 100 units. Confirm the trading unit shown for the specific security before ordering.
What is considered an odd lot on Bursa Malaysia?
Fewer than 100 shares, or a quantity not divisible by 100, is considered an odd lot for this purpose.
How do I buy or sell fewer than 100 Bursa shares?
Use your broker’s odd-lot order feature, check the separate order book, enter a limit price and monitor for partial matching.
Why might an odd-lot order take longer to fill?
The odd-lot book can have fewer counterparties or less depth at your price, delaying execution or producing a partial fill.
Do odd-lot shares trade at the same price as normal lots?
Not necessarily. Odd lots trade in a separate order book, so the best available bid or ask can differ from the Normal Market.
Are board-lot transaction fees different from odd-lot fees?
Broker charges and minimums can vary. Check the current fee schedule and trade estimate for both order types before trading.
