10 Common IPO Mistakes Indian Investors Make (and How to Avoid Them)

IPO investing looks simple from the outside. A company announces its IPO, investors apply, shares get allotted, and sometimes the stock lists at a premium.

Because of this, many investors treat IPOs like a shortcut to quick profits. But the reality is different.

Most IPO losses do not happen because investors picked a bad company. They happen because investors make avoidable mistakes before even submitting their application. Some rely entirely on GMP. Some never check valuations. Others lose allotment opportunities due to simple technical errors like not approving a UPI mandate.

The good news is that these mistakes are easy to avoid once you understand how IPO investing actually works. Let's look at the 10 most common IPO mistakes Indian investors make and how you can avoid them.

Mistake 1: Applying Based Only on GMP

One of the biggest IPO mistakes is treating GMP as the final decision-making tool.

GMP, or Grey Market Premium, is the price at which IPO shares unofficially trade before listing.

For example, if an IPO is priced at ₹100 and the GMP is ₹30, it suggests that some market participants expect the stock to list around ₹130.

The problem is that GMP is:

  • Unofficial
  • Unregulated
  • Not monitored by SEBI
  • Based on limited market participants
  • Vulnerable to sudden changes

Think of GMP like the crowd outside a cinema talking about an upcoming movie. People may be excited, but excitement does not guarantee the movie will be successful.

Similarly, GMP reflects market sentiment, not business quality. A strong company can have a moderate GMP. A weak company can temporarily show a high GMP.

How to avoid this mistake:

Use GMP only as a sentiment indicator.

Before applying, focus on:

  • Business quality
  • Revenue growth
  • Profitability
  • Debt levels
  • Valuation
  • Industry outlook

A good IPO decision should be based on business fundamentals and valuation, not on GMP.

Mistake 2: Not Skimming the DRHP at All

Many investors spend hours checking GMP websites but never spend even 20 minutes reading the company's DRHP.

The Draft Red Herring Prospectus (DRHP) is the document filed before the IPO. It contains almost everything an investor needs to know.

You do not need to read hundreds of pages. Even a quick review of six key sections can provide valuable insights:

  1. Business overview
  2. Industry overview
  3. Risk factors
  4. Financial performance
  5. Promoter information
  6. Objects of the issue

Think of it like buying a second-hand car. You may not inspect every nut and bolt, but you would still check the engine, service history, and ownership details.

The DRHP serves the same purpose.

How to avoid this mistake: Spend 15-20 minutes reviewing the most important sections before applying. That small effort can help you avoid many poor-quality IPOs.

Mistake 3: Ignoring Valuation vs Listed Peers

A great business can still be a poor investment if the valuation is too expensive.

This is where many IPO investors make mistakes. They focus on the company but ignore the price being asked.

Imagine two apartments in the same society. One is selling for ₹1 crore. The other is selling for ₹2 crore despite having similar features. Most buyers would question the higher price.

The same logic applies to IPOs. One common valuation metric is the Price-to-Earnings (P/E) ratio. It tells you how much investors are paying for every ₹1 of company earnings.

If an IPO is asking for a P/E of 100x while similar listed companies trade at 30x or 40x, investors should understand why such a premium is being demanded.

A high valuation is not automatically wrong. But it should be supported by strong growth, superior profitability, or a clear competitive advantage.

How to avoid this mistake:

Always compare:

  • P/E ratio
  • Price-to-Sales (P/S) ratio
  • Revenue growth
  • Profit margins

against listed peers before applying.

Mistake 4: Applying Only in Your Own Name

IPO allotment is often a probability game. In heavily subscribed IPOs, demand can be many times higher than available shares. In such situations, each eligible Demat account effectively becomes an additional chance in the allotment process.

Suppose a cricket stadium has 10,000 seats but 1 lakh people want tickets. Having one ticket request gives you one chance. Having multiple valid requests increases your probability.

The same principle applies to IPO allotment.

How to avoid this:

If family members have their own:

  • PAN
  • Bank account
  • Demat account

they can independently apply for the IPO.

However, every application must be genuine and compliant with IPO rules. Duplicate applications from the same PAN are rejected.

Mistake 5: Not Approving the UPI Mandate in Time

This is probably the most frustrating IPO mistake because it has nothing to do with investment analysis.

You decide to apply for IPO. You submit the bid. Then you forget to approve the UPI mandate. As a result, the application becomes invalid.

The UPI mandate is the authorization that blocks funds in your bank account until the allotment process is completed. Without approval, your IPO application is incomplete.

How to avoid this:

After submitting your IPO application:

  • Open your UPI app
  • Check pending requests
  • Approve the mandate immediately

Do not wait until the final hours of the issue. Technical delays can happen. A few minutes of care can save an entire IPO application.

Mistake 6: Bidding Below the Cut-Off Price

Some investors try to save money by bidding below the highest price in the price band.

This can reduce allotment chances. The cut-off option tells the system that you are willing to buy shares at the final issue price decided by the company.

Think of it like booking a train ticket. If you are willing to travel regardless of whether the fare is ₹500 or ₹520, selecting the flexible option ensures you stay eligible.

Similarly, choosing the cut-off option helps ensure your bid remains valid if the final issue price is fixed at the upper end of the price band.

How to avoid this: Unless you have a specific valuation-based reason not to, retail investors generally benefit from bidding at the cut-off price.

Mistake 7: Confusing High Subscription with Guaranteed Gains

A heavily subscribed IPO often creates excitement. But high subscription does not guarantee listing gains.

Many investors assume that if lakhs of people apply, profits are certain. History shows otherwise.

For example, the IPO of Paytm was reportedly subscribed about 1.9 times overall, yet the stock listed significantly below its issue price. Similarly, the IPO of Life Insurance Corporation of India was oversubscribed overall but also listed below its issue price.

The lesson is simple. Subscription data measures demand during the IPO. It does not guarantee future market performance.

How to avoid this mistake:

Treat subscription numbers as one data point.

Also evaluate:

  • Business quality
  • Valuation
  • Growth prospects
  • Profitability
  • Competitive position

Strong demand and strong fundamentals are not always the same thing.

Mistake 8: Ignoring the Objects of the Issue (OFS vs Fresh Issue)

Many investors never check where the IPO money is actually going. This is a mistake.

There are two major components in most IPOs:

  • Fresh Issue: New shares are created and money goes to the company.
  • Offer for Sale (OFS): Existing shareholders sell their shares and receive the money.

Imagine a shop owner asking for money to open new stores. That is similar to a fresh issue.

Now imagine the owner simply selling some of his ownership and keeping the money. That is similar to an OFS.

Neither is automatically good or bad. But they tell very different stories.

If a large portion of the IPO consists of OFS, investors should understand why existing shareholders are reducing their stake.

How to avoid this mistake:

Read the "Objects of the Issue" section carefully.

Check:

  • How much is Fresh Issue
  • How much is OFS
  • How the company plans to use the funds

Understanding where the money goes often reveals management priorities.

Mistake 9: No Exit Plan for Listing Day

Many investors spend days researching an IPO but never decide what they will do after allotment. This creates emotional decision-making.

When the stock starts moving rapidly on listing day, investors often panic. Some sell too early. Others hold without a clear reason.

Imagine entering a cricket match without knowing whether you're batting defensively or chasing a high run rate. The strategy becomes unclear.

The same happens in IPO investing.

How to avoid this mistake:

Before listing day, define your plan.

Examples include:

  • Sell if gains exceed a certain percentage
  • Hold for one year if business quality remains strong
  • Exit if valuation becomes excessive

There is no universal rule.

The key is having a plan before emotions take over.

Mistake 10: Not Accounting for 20% STCG Tax on Gains

Many investors calculate listing gains but forget about taxes.

For shares sold within one year, gains are taxed as Short-Term Capital Gains (STCG).

As of June 2026, the STCG tax rate on listed equity shares is 20%. Investors should verify the latest tax rules before acting, as regulations can change.

Let's say you earn a ₹10,000 listing gain.

A 20% STCG tax would mean approximately ₹2,000 goes towards taxes, leaving an effective post-tax gain of around ₹8,000. This changes your actual return.

How to avoid this:

Always calculate:

  • Expected gain
  • Brokerage charges (if applicable)
  • Taxes

before estimating your final profit.

What matters is not gross return but the amount that actually reaches your bank account.

The Smart IPO Investor Checklist (Pre-Apply)

Before applying for any IPO, quickly run through this checklist:

  • Do I understand the business?
  • Have I checked the company's financial performance
  • Have I compared valuations with listed peers?
  • Have I reviewed the OFS and Fresh Issue mix?
  • Have I checked the promoter background?
  • Have I looked at GMP only as a sentiment indicator, not a decision tool?
  • Have I reviewed subscription data without getting carried away?
  • Do I understand the tax impact on gains?
  • Do I have an exit plan for listing day?
  • Have all eligible family Demat accounts applied separately, if appropriate?

IPO investing does not require predicting the future. It requires avoiding common mistakes and following a disciplined process. Before applying for any IPO, take a few minutes to run through this checklist. It won't guarantee allotment or listing gains, but it can help you make more informed and rational investment decisions.
