IPO listing day, explained
By InvestorTrack team · Last reviewed · 6 min read
Listing day is the day an IPO's shares begin trading on the exchange. It is the moment the grey market premium meets a real price, and it is the first time you can sell your allotted shares. This guide explains how the day works and what the terms mean.
Before listing day
Under SEBI's timeline, counted from T, the last day of bidding, the allotment is finalised on T+1, allotted shares are credited to demat accounts and unallotted money is released on T+2, and the shares list on T+3. Weekends and market holidays are not counted. The exact dates for each IPO are on its Allotment tab. Your shares should show in your demat account before trading starts.
The special pre-open session
A listed share normally trades with a price band around the previous close. A newly listed share has no previous close, so the exchange first runs a special pre-open session to discover the price. On the NSE, order entry runs from 9:00 AM to 9:45 AM, then the exchange matches the orders and finds the price at which the most shares can trade, called the equilibrium price. That price is the listing price. Regular trading begins at 10:00 AM.
No price band applies during this session, so the equilibrium price can be well above or below the issue price. If no price can be found, the exchange keeps the session going until it is. The timings can be revised, so the exchange's circular for the listing is the final word.
The price band after the listing price
Once regular trading starts, the share trades within a price band set around the listing price for the day. Under SEBI's framework, the first-day band for a mainboard IPO is 5% for issues up to ₹250 crore and 20% for larger issues. SME shares have their own rules. The exchange states the band that applies in its notice for each listing, so check it for the issue you are following.
A band does not cap the opening price, which is set in the pre-open session, only the movement after it.
Issue price, listing price and closing price
A listing gain is usually measured from the issue price to the listing price. Whether you gain depends on the price you sell at, not only the opening price, and on charges and tax. The GMP calculator shows the arithmetic, and the GMP track record compares GMP with the actual listing price across IPOs we tracked.
Can you sell on the listing day?
Yes, once the shares are credited and trading has started. Some investors sell on day one to take a gain or limit a loss, and some hold. Which is right depends on your own plans and is not something this site can advise on. It helps to decide what you will do before the day, because prices can move quickly in the first minutes of trading.
What to expect from past listings
IPOs have listed above, at and below their issue prices. The Subscription and GMP tabs on each IPO page show how past IPOs of a similar size or subscription listed, from our archive, with the number of IPOs behind the figure. It is context, not a forecast.
Frequently asked questions
What time does an IPO list?
On the NSE, the special pre-open session runs from 9:00 AM with order entry until 9:45 AM, the listing price is found after that, and regular trading begins at 10:00 AM. Check the exchange notice for any change.
What is the listing price of an IPO?
It is the opening price found in the special pre-open session, at which the most shares can be matched. It can be above or below the issue price.
Is there a circuit limit on the IPO listing day?
After the listing price is set, a price band applies for the rest of the day. Under SEBI's framework it is 5% for mainboard issues up to ₹250 crore and 20% for larger ones. SME shares have their own rules. The exchange's notice states the band.
When do IPO shares reach my demat account?
Allotted shares are credited around T+2, before the listing on T+3, where T is the last day of bidding. Check your demat account before trading starts.
Is the listing price the same as issue price plus GMP?
No. GMP is an unofficial guess made before listing. The listing price is found by the exchange on the day and can differ in either direction.
