India's 2026 IPO Boom, Why Retail Investors Keep Losing Money Despite Listing Gains

IPOs can deliver strong listing gains, but that does not make every IPO a good investment. The biggest IPO investing mistakes retail investors make are applying because of FOMO, treating GMP as a guaranteed listing price, ignoring valuation, chasing stocks after listing, and confusing allotment success with investment success. Data from nearly 400 Indian mainboard IPOs since 2020 shows why the listing-day story can be very different from the long-term outcome.

What are the biggest IPO investing mistakes retail investors make?

The biggest mistakes are usually behavioural rather than technical. Investors apply because an IPO is heavily subscribed, track the Grey Market Premium (GMP), assume a listing gain is almost certain, and often buy more after listing if they miss the allotment.

The problem is that these decisions focus on short-term demand rather than the business and valuation.

A better approach is to treat an IPO like any other stock investment. Study the business, financials, valuation, use of funds, existing shareholder selling and risks before deciding whether the issue deserves your capital.

Mistake 1: Applying for an IPO just because everyone else is

The Reliance Power IPO is a useful example of how market excitement can overwhelm analysis.

In January 2008, the issue was oversubscribed by nearly 73 times. It listed on 11 February 2008 and closed 17% below its issue price. The experience became a classic lesson in what happens when investors participate because an IPO is popular rather than because they understand the business. Contemporary reporting also recorded the sharp first-day decline.

Benjamin Graham made a similar point in The Intelligent Investor: new issues can generate spectacular short-term gains, but that does not make them sound investments.

The lesson is straightforward. Subscription numbers tell you how much demand exists. They do not tell you whether the IPO is attractively valued.

Mistake 2: Treating IPO GMP as a guaranteed listing price

GMP is one of the most closely watched numbers before an IPO lists. Investors often see a high Grey Market Premium and assume that the stock will list at a similar premium.

The grey market is unofficial and does not have the transparency of the regulated stock market. GMP can be useful as a sentiment indicator, but it should not be treated as a valuation tool or a guaranteed listing forecast.

Investors can track current IPO GMP data through Trendlyne IPO GMP and Grey Market Premium, but the number should be considered alongside business fundamentals and valuation.

A high GMP can tell you that market participants are optimistic. It cannot tell you whether that optimism is justified.

Mistake 3: Confusing a successful allotment with a successful investment

This is one of the most interesting problems in IPO investing.

Kevin Rock's 1986 research on IPO underpricing explains an important information gap. When an issue is attractive, informed investors can compete heavily for the shares. When an issue is less attractive, those investors may reduce their participation.

That creates what is commonly called the winner's curse.

A heavily oversubscribed IPO may give a retail investor very little allocation. A weaker IPO may give the investor exactly the shares they requested.

So receiving an allotment is not evidence that you have found a good investment. The correct question is not, Did I get the IPO? It is, At the issue price, am I buying a business at a reasonable valuation?

Mistake 4: Buying the stock aggressively after listing

Missing an IPO allotment often creates another behavioural trap.

The stock lists at a premium, the investor sees the price rising and decides to buy it in the secondary market. But by then, the initial demand may already be reflected in the price.

An analysis of nearly 400 Indian mainboard IPOs from 2020 to mid-July 2026 found that 286 closed above their allotment price on listing day, while 113 closed below it. The same analysis found that median returns for investors who received allotments were materially better than for investors who bought at the listing-day closing price across several holding periods.

That does not mean every IPO should be bought at issue price. It means investors should not assume that a strong listing automatically creates an attractive buying opportunity.

Sometimes the better decision after missing an IPO is simply to wait.

Mistake 5: Ignoring why existing shareholders are selling

An IPO is not always about the company raising fresh capital.

Offer for Sale, or OFS, allows existing shareholders to sell their holdings. In SEBI's study of 144 mainboard IPOs listed between April 2021 and December 2023, 65% of the total issue size was through OFS, meaning existing shareholders were selling shares rather than the company raising that money as fresh capital.

This does not automatically make an IPO bad. But investors should understand the transaction.

If a large portion of an IPO represents an exit by existing shareholders, ask why they are selling and what valuation the public market is being asked to accept.

The question is not whether promoters or private investors are allowed to sell. They are. The question is whether the price being offered to new investors adequately compensates them for taking on the future business risk.

Mistake 6: Looking at growth but ignoring valuation

A good company can still be a poor investment if the price is too high. This is particularly important with new-age businesses where investors may focus heavily on revenue growth, market opportunity or future profitability.

Indian mainboard IPO rules include eligibility requirements. Under SEBI's framework, the traditional route includes requirements such as net tangible assets of at least ₹3 crore in each of the preceding three full years, along with a minimum average pre-tax operating profit of ₹15 crore over the three most profitable years out of the preceding five. Growth companies can access the market through a different route involving higher QIB participation.

These rules establish eligibility for a public issue. They do not establish that the IPO is attractively priced.

Investors still need to compare valuation with listed peers, profitability, cash flows, debt, margins and the growth assumptions already reflected in the issue price.

What does the IPO data since 2020 tell investors?

The broader data provides a useful reality check.

The analysis of nearly 400 mainboard IPOs from 2020 to mid-July 2026 found that approximately 70% delivered a positive listing-day close relative to the issue price. But as of 17 July 2026, 245 were still above their issue price while 154 were below it.

This is why listing gains should not be confused with long-term returns.

The data also shows how IPO activity has expanded. Mainboard listings increased from 14 in 2020 to 64 in 2021, 90 in 2024 and 104 in 2025.

The key point is not that IPOs are good or bad. The key point is that investors need to separate listing performance from business performance.

What does SEBI's IPO investor study reveal about retail behaviour?

SEBI's own study provides another important piece of evidence.

The regulator analysed 144 mainboard IPOs listed between April 2021 and December 2023. It found that 54% of IPO shares allotted to investors, excluding anchor investors, were sold within a week of listing by value. Individual investors sold 50.2% of their allotted shares by value within a week, while retail investors sold 42.7%.

When IPO returns exceeded 20%, individual investors sold 67.6% of their allotted shares by value within a week. When returns were negative, the corresponding figure was 23.3%.

This is important because it shows that IPO participation is often driven by short-term outcomes.

Investors tend to sell when they see quick gains. That is consistent with the listing-gain mindset that drives much of the retail IPO market.

For more context, see Business Standard's coverage of the SEBI IPO investor study.

How should retail investors evaluate an IPO?

The process does not need to be complicated. Before applying, investors should answer five questions:

• • What does the company actually do?
• • How fast are revenue and profits growing?
• • What valuation is the IPO asking investors to pay?
• • How much of the issue is fresh capital versus OFS?
• • Would I buy this company at the same valuation if it had already been listed for five years?

The fifth question is particularly useful because it removes some of the IPO excitement. If the company were already listed, would the investor still consider the valuation attractive?

If the answer is no, the fact that it is a new IPO should not change the decision.

Investors should also read the key sections of the DRHP or RHP, particularly the risk factors, financial statements, objects of the issue, promoter information and related-party transactions.

Should investors avoid IPOs altogether?

No. The data does not support an argument for completely avoiding IPOs. Around 70% of the IPOs in the analysed dataset delivered listing-day gains, and some companies went on to create substantial long-term wealth.

The problem is indiscriminate participation. An investor who applies to every popular IPO, relies on GMP, ignores valuation and then chases the stock after listing is following a very different strategy from an investor who evaluates the business and price independently.

That distinction is more important than whether the investment happens to be an IPO.

Frequently Asked Questions

• Is IPO investing risky for retail investors?

Yes. IPOs can generate strong listing gains, but they can also decline sharply after listing. Retail investors should evaluate the business and valuation rather than assuming that oversubscription or GMP reduces risk.

• Is IPO GMP reliable?

GMP can indicate market sentiment, but it is not a guaranteed listing-price indicator. It is based on an unofficial market and should not replace fundamental analysis.

• Is getting an IPO allotment a good sign?

Not necessarily. An allotment only means that shares were allocated to you. A good investment depends on the business quality, valuation and future earnings potential.

• Should I buy an IPO stock if I miss the allotment?

There is no need to buy immediately. If the stock lists at a significant premium, waiting for financial results and allowing initial volatility to settle can provide more information before making a decision.

• What is the biggest IPO mistake retail investors make?

The biggest mistake is allowing short-term market excitement to replace investment analysis. FOMO, GMP, subscription numbers and listing gains can all attract attention, but none answers the central question: is the business worth the price being paid?

Risk disclaimer: Past performance and historical IPO returns are not indicative of future results. IPO investments can involve significant volatility and the possibility of capital loss, including substantial or complete loss of invested capital.
