Most IPO investors quote the average listing gain. In 2024, that number was 30.25%. Sounds fantastic — until you realise the median was 15.2%, and in 2025 it crashed to 3.8%. After 20% STCG tax, STT, and DP charges, that 3.8% median gain on a Rs 15,000 lot becomes roughly Rs 430 in your pocket. This article breaks down the actual math of flipping versus holding, with real tax calculations, anchor lock-in impact, and survival rates that most IPO analyses conveniently skip.
Flipping Returns: 2024 vs 2025
The flipping strategy delivered dramatically different results across two years.
| Metric | 2024 | 2025 |
|---|---|---|
| Average listing gain | 30.25% | 9.9% |
| Median listing gain | 15.2% | 3.8% |
| Positive listings | 80% | 65% |
| Net profit on Rs 15,000 lot (at median) | ~Rs 1,750 | ~Rs 430 |
2024 was a bull market year for IPOs. Retail sentiment was strong, grey market premiums were elevated, and institutional demand pushed listing prices higher. 2025 brought a correction — not just in listing gains but in the probability of making money at all. One in three IPOs listed flat or negative.
The takeaway: flipping is a market-cycle strategy, not an all-weather strategy. In strong markets it works. In normal or weak markets, the median flipper barely covers transaction costs.
The Median vs Average Trap
This is the single most important statistical concept for IPO investors to understand.
The average listing gain in 2024 was 30.25%. A few mega-IPOs with 50-100%+ listing gains pulled this number up. The median — the point where half the IPOs did better and half did worse — was 15.2%.
Why this matters:
- You do not get the average. You get whatever IPO you are allotted in.
- Allotment is essentially random for retail investors in oversubscribed issues.
- Your expected return should be based on the median, not the average.
| Year | Average Gain | Median Gain | Difference |
|---|---|---|---|
| 2024 | 30.25% | 15.2% | 15.05 pp |
| 2025 | 9.9% | 3.8% | 6.1 pp |
The average overstates your realistic expectation by 2x or more. Every IPO return tweet, YouTube video, or blog post quoting average returns is giving you a misleading picture. If someone tells you “IPOs gave 30% returns in 2024,” the honest answer is “half of them gave less than 15.2%, and after tax you kept less than 12%.”
Complete Tax Math: STCG vs LTCG
Budget 2024 changed the tax landscape for equity investors. Here is the current structure:
| Parameter | STCG (under 12 months) | LTCG (12+ months) |
|---|---|---|
| Tax rate | 20% | 12.5% |
| Exemption limit | None | Rs 1.25 lakh/year |
| Applicable on | Full gain | Gain above exemption |
| Previous rate | 15% | 10% |
The 5 percentage point increase in STCG (from 15% to 20%) directly hurts flippers. The LTCG increase from 10% to 12.5% was partially offset by raising the exemption from Rs 1 lakh to Rs 1.25 lakh.
Worked Example: Flipping on Listing Day
| Item | Amount |
|---|---|
| Allotment: 30 shares at Rs 500 | Rs 15,000 |
| Listing price: Rs 600 (+20%) | Rs 18,000 |
| Gross profit | Rs 3,000 |
| STT (0.1% of sell value) | Rs 18 |
| DP charges | Rs 15.34 |
| Brokerage (Zerodha delivery) | Rs 0 |
| SEBI fee + stamp duty | ~Rs 2 |
| STCG tax (20% of Rs 3,000) | Rs 600 |
| Net profit | ~Rs 2,367 |
Your Rs 3,000 gross profit becomes Rs 2,367 — a 21% haircut from taxes and charges alone.
Worked Example: Holding 12+ Months
| Item | Amount |
|---|---|
| Purchase: 30 shares at Rs 500 | Rs 15,000 |
| Sell after 12 months at Rs 700 | Rs 21,000 |
| Gross profit | Rs 6,000 |
| STT (0.1% of sell value) | Rs 21 |
| DP charges | Rs 15.34 |
| LTCG tax (12.5% above Rs 1.25L exemption) | Rs 0* |
| Net profit | ~Rs 5,965 |
*Assuming total LTCG for the year stays within the Rs 1.25 lakh exemption.
The difference is stark: Rs 2,367 net from flipping versus Rs 5,965 from holding — but only if the stock actually appreciates over 12 months. That is a very big “if.”

Post-Listing Holding Risk: Only 41% Retain Gains
Here is the data point that changes the holding argument:
| Metric | 2024 | 2025 |
|---|---|---|
| IPOs trading above issue price months later | 70% | ~55% |
| IPOs that retained listing gains | Not tracked | 41% |
In 2025, 59% of IPOs gave up their listing day gains within months. Some notable collapses:
- Hyundai Motor India: Listed at a discount, fell 10% below issue price
- Popular Vehicles: Crashed 46% from issue price
Holding is not a “safe” default. The tax math favours holding — 12.5% versus 20% — but the stock price risk overwhelms the tax saving. A 7.5 percentage point tax saving is irrelevant when 6 out of 10 stocks are falling below their listing price.
The rational approach: evaluate each IPO individually after listing. Do not hold simply because “LTCG tax is lower.” Hold because the business fundamentals justify a 12-month commitment.
Anchor Lock-in Expiry: The 30-Day and 90-Day Danger Zones
Anchor investors — mutual funds, insurance companies, foreign institutional investors — receive preferential allotment before the IPO opens. Their lock-in schedule creates predictable selling pressure:
| Lock-in Period | Shares Released | Impact |
|---|---|---|
| 30 days from allotment | 50% of anchor allocation | First wave of institutional supply |
| 90 days from allotment | Remaining 50% | Second wave of institutional supply |
In recent cycles, approximately Rs 32.46 billion worth of shares entered the market from anchor lock-in expiries alone.
What this means for retail holders:
- Day 30 is the first danger zone. If institutional investors are underwater or see better opportunities elsewhere, they sell. Weak IPOs see 5-15% drops around this date.
- Day 90 is the second danger zone. Another wave of supply hits. If the stock has not built momentum, this creates further downward pressure.
- The holding period from listing to 12 months (LTCG qualification) passes through both danger zones. You must survive two waves of institutional selling to reach the lower tax bracket.
Track anchor lock-in expiry dates for any IPO you are holding. The information is available in the IPO prospectus and on registrar websites.
IPO Funding Economics for Flippers
Under ASBA, your application money stays in your savings account earning 3-4% annually while blocked for 6-8 days. The direct cost is negligible — roughly Rs 7-10 interest on a Rs 15,000 application.
The real economics are about allotment probability and opportunity cost:
| Scenario | Calculation |
|---|---|
| IPO subscribed 50x in retail | ~2% allotment probability |
| Applications needed for 1 allotment | ~50 |
| Capital blocked per application | Rs 15,000 |
| Total capital blocked across attempts | Rs 7,50,000 across the year |
| Actual profit from 1 allotment (median 2025) | ~Rs 430 |
If you are applying to every IPO hoping to flip, your effective return on capital deployed (accounting for failed applications) is in low single digits. Serious flippers apply through multiple demat accounts — spouse, parents, HUF — to improve odds. Each account requires separate capital blocking.
The opportunity cost: that Rs 15,000-1,50,000 blocked in savings at 3.5% could earn 7%+ in a liquid fund. Over dozens of applications per year, the difference adds up.

Decision Framework: When to Flip, When to Hold
There is no universal answer. Use this framework based on data, not sentiment:
Flip When
- Listing gain exceeds 15% — lock in the profit before anchor expiry pressure
- The IPO was overvalued at issue price (PE significantly above industry average)
- Market sentiment is deteriorating — falling indices, rising VIX
- You have already hit your LTCG exemption limit for the year
- The company has no visible earnings growth catalyst for the next 12 months
Hold When
- Your total LTCG for the year is well below Rs 1.25 lakh — the entire gain could be tax-free
- The company has strong quarterly earnings growth visible in post-listing results
- The stock corrects 10-15% post-listing to more attractive valuations
- Institutional investors are increasing holdings (visible in shareholding data)
- The business model has a clear moat and the IPO valuation was reasonable
Neither — Exit at a Loss When
- The stock lists below issue price with no fundamental catalyst
- Book the short-term capital loss and use it to offset other STCG or LTCG gains
- A Rs 3,000 loss saves you Rs 600 in tax if set off against other short-term gains

The Survivorship Bias in IPO Return Data
Every statistic in this article — and every IPO return analysis you read — suffers from survivorship bias to some degree. Here is what gets excluded:
- Withdrawn IPOs: Companies that filed DRHPs but pulled their IPOs due to weak demand. These would-be negative returns are not counted.
- SME IPOs with no liquidity: Many SME IPOs list at massive premiums but have zero liquidity. You cannot actually sell at the “listing price” because there are no buyers at that level.
- Allotment-weighted returns: Return statistics treat every IPO equally. But retail investors are far more likely to get allotted in unpopular IPOs (low subscription) and far less likely in popular ones (high subscription). Your allotment-weighted return is worse than the equal-weighted average.
- Post-listing delistings: Companies that delist or get suspended after listing disappear from most databases.
The honest picture:
| What gets reported | What actually happens |
|---|---|
| Average listing gain: 30.25% | Median gain: 15.2% |
| “80% positive listings” | After tax and costs, profitable listings are fewer |
| Annual IPO returns | Ignores capital blocked in failed applications |
| Listing day return | Ignores 59% that lost gains within months |
The Bottom Line
IPO flipping is a low-probability, moderate-reward strategy that works best in bull markets. The 2024 data made it look easy. The 2025 data brought reality.
The math in summary:
- Flipping: Median net profit of Rs 430 per lot in 2025 after 20% STCG tax, with 65% probability of positive listing
- Holding 12 months: Potentially zero tax on gains under Rs 1.25 lakh, but only 41% of IPOs retained listing gains
- Tax difference: 7.5 percentage points (20% STCG vs 12.5% LTCG), which on a Rs 3,000 profit is Rs 225
Do not optimise for tax when the stock price risk is 5-10x larger than the tax saving. Flip in strong markets when gains are meaningful. Hold only when fundamentals justify the risk of two anchor lock-in expiry waves and general market volatility over 12 months. And always remember: the IPO you got allotted in is probably not the one with the 100% listing gain — it is the one nobody else wanted.
