SEBI plays a role in determining this minimum number, and investors must purchase shares in multiples of 50.

How do you Calculate the Lot Size of an IPO? 

The IPO paperwork the firm publishes will also include information on the lot size. Let us assume that a firm issuing 10,000 shares in an IPO with a minimum lot size of 200 shares. To participate in the IPO, you must acquire at least 200 shares (1 lot). Investors may purchase shares in lots (multiples of 200) up to the maximum lot size. In this case, the number of lots distributed by the corporation may be known using a simple formula, which is:

Total lots issued equals the number of issued shares divided by the minimum lot size. Total lots issued: 10000/200 = 50 lots.

Let's suppose the maximum lot size is six lots. It indicates an investor cannot buy more than six lots (1200 shares) during the IPO.

What is the Market Lot Size for an IPO?

Now that you've grasped lot size in an IPO, let's talk about market lot size. The market lot size is completely different from the IPO lot size. It is the minimal number of shares that can be traded on stock markets following the IPO's close. Assume a company's market lot size is 200 shares. It implies that when the IPO closes, investors must purchase at least 200 shares on stock markets. The IPO lot size may be greater than the market lot size. For example, the same business may have required investors to purchase at least two lots (400 shares) to participate in the IPO.

How do Minimum Order Quantity and Market Lot Size Affect an IPO?

The grey market premium (GMP) is a measure of investor interest in an Initial Public Offering (IPO) before it is listed on the official stock exchange. It represents the difference between the IPO grey market price and the IPO price, indicating the price investors are willing to pay for IPO shares. A high GMP indicates strong demand and potential price appreciation, while a low or negative GMP may indicate weaker demand or downward pressure on the stock's price.

The GMP serves as an indicator of market sentiment, but investors should exercise caution and evaluate the IPO's merits before making investment decisions. The market lot size and minimum order quantity are crucial factors that influence the IPO's success, which are often dependent on the price of both issued shares. Large market lot sizes can make it difficult for small investors to participate, while high minimum order quantities can make it difficult for buyers to find sellers willing to trade lower quantities.

Establishing restrictions on market lot size and MOQ is necessary to prevent investors from purchasing too many shares at once, aiming to maintain equilibrium.
