Board Lot

Trading in stocks involves some basic concepts that every investor must know. One such important concept is that of a ‘Board Lot.’ Simply put, a Board Lot refers to the minimum number of shares that can be bought or sold in a single transaction on the stock exchange.  

This article will examine the concept of Board Lot in depth and discuss how it impacts trading activities. We will also discuss its importance and how it can affect investors. By understanding Board Lot better, readers can make wise investment decisions. 

What is a Board Lot?  

A board lot is the minimum number of shares that can be bought or sold in a single transaction on the stock exchange. This number can vary depending on which exchange you are trading on. In the US, the standard board lot size is 100 shares. In Singapore, the board lot size is typically 1000 shares for most counters.  

This means that if you want to place an order to purchase shares on the stock market, you need to buy at least 100 or 1000 shares, depending on the exchange. You cannot place an order to buy just 15 or 24 shares. The order has to be in multiples of the standard board lot quantity. This standardisation helps increase liquidity and makes trading more efficient. 

Understanding Board Lots 

When you first start investing in stocks, one thing you will quickly come across is the term “board lot.” But what does it really mean? In this section, we’ll break down board lots into simple terms. 

A board lot is the minimum number of shares that must be bought or sold in one trade on the stock exchange. Each exchange sets this minimum number. For example, in the U.S., the board lot size is usually 100 shares. In Singapore, it’s often 1,000 shares. 

This minimum was put in place so the exchanges could run smoothly. Imagine if people could buy and sell stocks one share at a time – it would be chaos! The exchange computers and employees couldn’t keep up with millions of tiny orders flooding in every second. 

Setting a board lot size forces investors to make trades of a decent size. This lets the “big boys” who trade huge chunks of shares do their thing without getting delayed. It also helps keep trading costs down for everyone. 

Knowing your board lot size is helpful. Brokers usually charge the same fee whether you trade 100 or 1,000 shares. Plus, your order has a better chance of being filled out immediately. In the end, remember – a board lot is the minimum “chunk” of shares you need to trade on the exchange. This keeps everything running in an orderly fashion!

Importance of Board Lot 

Understanding the board lot size is very important for all stock market investors. Here are some key reasons why: 

• It allows for smooth trading: With no minimum order size requirement, exchanges must deal with very small quantities from different brokers. This would make it challenging to match buy and sell orders. Board lots help standardise order sizes so matching happens smoothly. 

• It promotes liquidity: By setting a minimum lot size, stocks are more likely to have pending buy and sell orders comparable in quantity. This increases liquidity as there are always buyers and sellers for that volume of shares. 

• It reduces transaction costs: Brokers do not have to process small, odd-lot orders, which are more expensive. Board lots keep all trading bulked up in round, easy-to-manage numbers like 100, 200, 500 shares, etc. This helps save on delivery and settlement costs. 

• It maintains orderly markets: Requiring round lot quantities maintains uniformity and structure when placing orders. This prevents chaos and confusion during high volume or volatile periods in the market. 

• It benefits large investors: Institutions and professional traders deal in sizable volumes. Standard lot sizes are manageable for them and do not significantly increase trading costs. 

• Small investors also benefit indirectly: While odd lots are a hurdle for retail buyers, board lots assure stability and liquidity. This helps small investors, too, as they get fair and competitive share prices over the long run. 

Knowing the board lot is thus essential for all market players to plan their trade quantities, minimise costs, and comply with exchange rules. It helps make equity markets organised and cost-effective. 

Impact of Board Lot 

The board lot size set by an exchange can influence small and large investors. The minimum lot size can act as a deterrent for retail traders and investors who may want to purchase just a few shares. It may not be viable for them to buy 100 shares in one go due to capital constraints.  

On the other hand, institutional traders who deal in large volumes are not significantly impacted and can easily trade in multiples of the board lot. However, for stocks with very high per-share prices, even a board lot quantity may seem like a large investment for smaller players. Exchanges review board lot sizes from time to time based on investor feedback. Overall, a suitably determined board lot promotes depth and liquidity in a stock. 

Examples of Board Lot 

To understand this better in practical terms, let us look at some examples: 

• An investor wants to purchase Apple Inc. shares, which trades on the NASDAQ. The board lot here is 100 shares. So, the minimum the investor can buy is 100 shares and multiples of 100, only 200, 300, and so on. 

• Another investor is interested in Singapore-listed DBS Group Holdings. On SGX, the board lot for DBS is also 100 shares, so this investor needs to purchase at least 100 shares during one transaction. 

• A trader is looking at Nestle on the SIX Swiss Exchange. The board lot there is typically set at 30 shares. Hence, this trader can order only for quantities like 30, 60, 90 shares, and so on. 

• A fund manager is analysing shares of BHP Group in Australia. The standard board lot on the ASX is defined as parcel sizes of 200 units. Therefore, the minimum order this fund can place is for 200 shares. 

Conclusion 

The concept of a board lot is an important reference point for all stock market participants. Understanding the standard lot size or minimum trading unit set by each exchange allows traders and investors to participate in an orderly manner. It promotes liquidity and transaction efficiency. While it may deter some small shareholders, board lots are necessary to establish stock depth and stability. Awareness of this baseline requirement is necessary to reap profits through timely investments in the equity market.
