On listing day, a newly listed IPO stock is not available for normal (continuous) trading right away. It first goes through a special pre-open session that discovers the listing price, and continuous trading begins only after that session ends. You can also only sell your shares once they've actually been credited to your demat account, which may not reflect until close to listing day.
Why can't I trade the stock as soon as the market opens?
A freshly listed stock opens with a special pre-open session (9:00 AM–10:00 AM), a call auction that discovers the opening price, instead of jumping straight into continuous trading. Only limit orders are accepted in it, and continuous trading begins at 10:00 AM. Because the opening price is set by this auction, the stock can list well above or below its issue price—the market sets it, not the company.
For exactly how the session works—its phases and the price limits (operating range) that apply—see What is the Special Pre-Open Session?.
How much can the price move on listing day?
Once the opening price is discovered and regular trading starts at 10:00 AM, standard daily circuit limits apply for the rest of the day, based on the issue size:
- Large IPOs (issue size above ₹250 crore) — a ±20% circuit filter.
- Small IPOs (issue size up to ₹250 crore) — a stricter ±5% circuit filter, and these typically trade in the Trade-for-Trade (T2T) segment for the first 10 days.
Why don't I see my allotted shares in my holdings yet?
Allotted shares are credited to your demat account around the time of listing, but the credit may not reflect immediately—sometimes it appears only on listing day morning, and occasionally a little later. A few things to know:
- You can sell your allotted shares only once they're credited to your demat and showing in your holdings.
- If you were only partially allotted, you'll receive just the allotted shares; the rest of your blocked amount is released—see When will I get my money back after an IPO?.
- If the shares aren't showing by listing day, check your application status first—see How do I check my IPO application status?—and confirm the credit with your depository (DP) if needed.
Things to keep in mind
- The opening price is set by the market in the special pre-open session, so it can list above or below the issue price.
- You can't sell shares that aren't in your demat yet, even if the stock has listed and is trading.
