Introduction to IPO

Chapter 17

IPO Listing and Trading

IPO listing is the process through which a private company's shares are officially placed on a stock exchange, allowing them to be traded publicly. Once listed, any investor can buy or sell these shares through a stock broker. This marks the final step in the IPO journey, occurring after shares are allocated and credited to investors' demat accounts. The company selects a stock exchange for listing, with mainboard IPOs potentially appearing on both NSE and BSE, whereas SME IPOs are limited to one exchange. Initially, IPO shares are offered in the primary market, but after listing, they become part of the secondary market.

IPO Listing Date

The IPO Listing Date is the day shares of a company are first made available for trading on a recognized stock exchange. This is when investors can start buying and selling the company's shares on the market. Typically, the IPO listing occurs about six business days after the IPO's closing date, with the final date being announced on the exchange's website. You can check the listing dates and other details at iposcanner.ai.

*Note: Starting December 1, 2023, the timeline for listing public issues will be shortened to three working days after the issue closes.

IPO Listing Process in India

The IPO listing process involves getting a company's shares ready for trading on stock exchanges. This is one of the last steps in the IPO procedure.

Here's a breakdown of the steps involved:

  1. The company enlists one or more merchant bankers (lead managers).
  2. Merchant bankers assess the company's eligibility and ensure it meets all listing requirements.
  3. Approval is sought from stock exchanges for the IPO.
  4. Draft offer documents are submitted to SEBI and the exchanges for approval.
  5. Other essential intermediaries are brought on board.
  6. The company promotes the IPO through public relations and advertising.
  7. The IPO is launched for investor bidding.
  8. Allotment is finalized in coordination with the exchange(s).
  9. The procedure for refunding and crediting shares to the demat accounts of investors is initiated.
  10. Finally, the shares are listed on the chosen stock exchange(s).

IPO Listing Time

On the day of listing, the process kicks off with a ceremonial event, aligning with the market opening at 9:00 a.m. The trading day is split into two sessions: the Pre-Open Session and the Regular Session.

1. Pre-Open Trading Session/Special Pre-Open Session

This special session helps in determining the best price for the IPO shares on their first trading day. It lasts for an hour from 9:00 a.m. to 10:00 a.m. and is divided into three parts:

  1. Order placement session
  2. Order matching and execution session
  3. Equilibrium price establishment

The equilibrium price is where the demand for shares matches their supply. To manage differences in equilibrium prices between BSE and NSE, a Common Equilibrium Price (CEP) is used to set the Listing Price. For example, if BSE's price is ₹120 for 300 shares and NSE's is ₹100 for 500 shares, the CEP becomes ₹107.50.

The price band on both exchanges will be 5% around the CEP. The final CEP is calculated as a volume-weighted average of individual exchanges' prices.

IPO Listing Pre-Open Session Activities

Steps to Buy/Sell IPO Shares in Pre-Open Market

  1. Place your order at the desired price.
  2. If the listing price matches or favors your order price, it will execute at the listing price.
  3. Unexecuted orders carry over to the regular trading session.

For instance, if an IPO lists at ₹510, here's how pre-market orders might execute:

Sell515No

Pre-Open IPO Shares Trading Rules

  • Orders can be entered, changed, or canceled until 9:45 AM.
  • Trading occurs between 9:45 and 9:55 AM.
  • No price bands apply during this session.
  • Only limit orders are accepted; market orders are not.
  • Orders not executed will move to the regular session.

2. Regular Session

In the regular session, IPO shares trade like any other stock. The stock exchange sets an upper and lower price range based on the listing price.

IPO Listing Price

The listing price is the initial trading price of an IPO share on its listing day. It is determined during the Pre-Open Session from 9:45 a.m. to 9:55 a.m. While there are no circuit limits during this session, there is typically a floor and ceiling for price discovery. For recent IPOs, these limits have been around 25% and 75%, respectively. However, these limits can vary.

IPO Listing Day Circuit Limit

To manage sharp price movements on the listing day, stock exchanges set circuit limits as a percentage of the listing price. Here are the general rules:

  1. For an issue size up to ₹250 crores, the price band is 5%.
  2. For an issue size over ₹250 crores, the price band is 20%.

IPO Shares Listing Groups

When a company lists an IPO, the exchanges also specify the stock's listing group. This group determines settlement methods and whether intraday trading is permitted.

Newly listed companies are categorized by their issue volume, with separate group codes for NSE and BSE.

BSE Group List

BSE classifies new equity stocks into groups A, B, or T:

BSE Group CodeBasis of GroupingSettlement TypeIntraday Trading
AMarket capitalization ≥ ₹1 lakh croreRollingYes
BIssue size > ₹250 croresRollingYes
TIssue size ≤ ₹250 croresTrade for tradeNo

Investment trusts like REITs and InvITs are listed in the 'IF' group.

NSE Series List

NSE uses series to categorize IPO stocks into EQ and BE:

NSE SeriesBasis of GroupingSettlement TypeIntraday Trading

Investment Trusts (InvIT) NSE Listing Groups

Important Points:

  • As per SEBI's circular on IPO trading controls, IPOs with an issue size of up to ₹250 crores will trade in the TFT segment for the first 10 days after listing. Afterward, they move to the rolling segment.
  • Exchanges regularly review listing groups, and shares can shift based on trading volume, liquidity, risks, and other factors. Any group changes are communicated via notifications and circulars.
