IPOs Difference Between Book Building and Fixed Price: Which One Favors Retail Investors?

👉 Introduction

When a company decides to go public, it chooses between two IPO pricing methods used in IPOs: Fixed Price and Book Building. Each type works differently and affects how shares are allocated, priced, and traded in IPOs. Retail investors benefit differently based on the method. In this guide, we unpack both IPO models in simple terms and show which method favors retail participation.

What Are Fixed Price IPOs?

In a Fixed Price IPO, the company sets a firm price per share before going public. Retail investors see this price in advance. They know exactly how much they must pay., apply at that fixed rate, and block the funds in advance. If they don’t get shares, they get refunds.

Highlights of Fixed Price IPOs:

• Price stays unchanged throughout the offer
• Investors know in advance what to pay
• Simple process for retail investors
• But may misprice shares: too high or too low

What Are Book Building IPOs?

In a Book Building IPO, the company sets a price range (e.g., ₹50–₹70). Investors bid within this range: they pick quantity and price. After the deadline, the final price (cut-off) is set where demand matches supply.

Highlights of Book Building IPOs:

• Price range is public; final price is demand-driven
• Daily updates on subscription help investors decide
• Offers better price discovery and transparency
• More flexible pricing than fixed method

Key Differences: A Side-by-Side Look

Which One Is Better for Retail Investors?

Both methods serve different investor styles.

Fixed Price:

• Good for beginners who want clarity and ease
• No bidding strategy needed
• However, it may leave out profits if priced too low
• It may turn expensive if priced too high

Book Building:

• Deals with one price (cut-off) for retail bids
• Retailers often get priority at cut-off
• They see demand live and can adjust plans

Verdict: Book Building generally favors retail investors more. It brings better pricing, fair chances, and transparency.
