Setting the price of an IPO is a delicate balancing act. If a company prices its shares too aggressively, institutional investors will stay away, leading to undersubscription. If priced too conservatively, the company leaves substantial capital on the table. Here is how modern IPO pricing works.
1. What is Book Building?
In a Book Built IPO, the issuer does not declare a single price upfront. Instead, they announce a price band (e.g., ₹450 to ₹475 per share). Over the 3-day bidding window, institutional, HNI, and retail investors submit bids indicating the quantity of shares and price they are willing to pay.
2. Fixed Price vs Book Built Issues
In a Fixed Price issue, shares are offered at a predetermined single price. Today, over 95% of Mainboard IPOs utilize the book building route because it allows dynamic price discovery based on real market demand.
Book Building Demand
To observe how institutional and retail interest develops during the book building window, review updated bidding figures via category-wise IPO subscription status.
3. How Investment Bankers Set the Price Band
Merchant bankers perform discounted cash flow (DCF) modeling, peer comparison with listed competitors on NSE/BSE, and analyze Price-to-Earnings (P/E) multiples to determine a fair valuation corridor.
4. Price Discovery and Cut-Off Mechanism
At the close of bidding, all bids are aggregated into an order book. The price point at which the entire issue can be successfully sold becomes the final Cut-Off Price.
5. Measuring Market Demand & Premium
When the discovered price leaves money on the table for retail investors, unofficial dealers adjust the IPO grey market price accordingly. You can check expected listing prices and live premium trends on our GMP today dashboard.
