Your IPO stock can fall even without bad results — simply because locked shares become free to sell. Here is what every retail investor must check before the next wave hits over the next three months.
The risk hiding in plain sight
Picture this. You bought shares in a company six months ago right after its IPO. The business is doing well. Revenue is growing. The management has not said anything alarming. Yet the stock has quietly dropped 12% over the last two weeks — without a single piece of bad news to justify it.
What happened? A category of shareholders whose lock-in period just expired quietly started selling. Not all of them, not in a panic — just enough steady supply entering the market each day to tip the demand-supply balance. This is the lock-in expiry effect, and it catches retail investors off guard more often than any earnings miss or macro shock.
Right now, India is entering one of the largest lock-in expiry windows in recent memory. According to Nuvama Alternative and Quantitative Research, 73 newly listed companies are set to see shares worth $34 billion become eligible for trading over the next three months. These are companies that listed around November 2025 and are now hitting their six-month shareholder lock-in endpoints — with more tranches to follow across one-year and eighteen-month windows.
“Not all of these shares will come for sale — but the supply overhang alone is enough to move prices before a single share is actually sold.”
That is the subtlety worth understanding. Markets are forward-looking. The moment a lock-in expiry date appears on the calendar, professional traders start pricing in the risk. By the time the date actually arrives, the damage is often already half done — baked into a stock that has quietly drifted lower while retail investors were still reading the last quarterly report.

What does lock-in expiry actually mean?
When a company goes public in India, SEBI requires certain shareholders to hold their shares for a mandatory period before they can sell in the open market. This is the lock-in period. The intent is straightforward — it stops early investors from immediately offloading shares onto new retail buyers the moment the IPO lists, which would otherwise crash the price.
During the lock-in period, those shares simply do not exist in the tradeable universe. The free float — the portion of shares actively available to buy and sell — is deliberately constrained. Once the lock-in expires, those shares enter the market. Free float increases. Supply rises. If demand does not rise to match, the stock price adjusts down.
But not all lock-ins are the same. The three types each carry different risk profiles, different timeframes, and very different seller motivations. Understanding who is unlocking matters more than just knowing how many shares are unlocking.
Before and after: visualizing the supply shift
The easiest way to understand lock-in risk is to think of it as a tap being turned on. Before expiry, only a fraction of a company’s shares trade each day. After expiry, a new pool of supply becomes available — sometimes small, sometimes large enough to completely reshape the demand-supply equation.
The Meesho case from January 2026 illustrates this perfectly. When the company’s one-month lock-in expired, around 110 million shares — roughly 2% of equity — became eligible for trading. The stock was already up over 56% from its IPO price at that point. It hit a 5% lower circuit that day. No bad news. No earnings miss. Just the calendar doing its work.
Who unlocks next — and when
The first expiries of the current wave began on May 20, 2026. Emmvee Photovoltaic Power, Fujiyama Power Systems and Capillary Technologies — all listed on the NSE and BSE in November 2025 — hit their six-month lock-in endpoints. Capillary Technologies is particularly notable: 56% of its outstanding shares are eligible to trade, an unusually large unlock quantum for a mainboard listing.
The queue through August is long, and several names carry unlock sizes exceeding 50% of equity. Nuvama’s report specifically flags Meesho, Billionbrains Garage Ventures (Groww’s parent), Pine Labs, Aegis Vopak Terminals, Shadowfax Technologies and Bharat Coking Coal as the biggest events to watch through August 2026.
| Company | Expiry Window | Lock-in Type | Unlock % | Investor Profile | Risk |
|---|---|---|---|---|---|
| Emmvee Photovoltaic Power | May 20, 2026 | 6-month | ~4% | Mixed | Moderate |
| Fujiyama Power Systems | May 20, 2026 | 6-month | ~16% | Non-promoter heavy | Watch |
| Capillary Technologies | May 20, 2026 | 6-month | ~56% | VC / PE dominant | High |
| Borana Weaves | May 27, 2026 | 6-month | ~45% | Non-promoter | High |

Which sectors carry the most lock-in risk right now
Lock-in risk is not evenly spread across sectors. New-age tech companies and consumer internet names — where VC/PE ownership is structurally high and valuations were stretched at listing — face meaningfully more pressure than, say, an infrastructure or energy company where promoters dominate the cap table. Here is a sector-level read on where the overhang is most acute in this wave.
| Sector | Typical VC/PE Exposure | Unlock Impact Potential | Key Reason | What to watch on NiftyTrader |
|---|---|---|---|---|
| Consumer Internet / Fintech | Very High | VC funds hold 40–60%+ in names like Meesho, Groww, Shadowfax. High listing gains increase exit motivation. | FII/DII flow, block deal alerts, promoter pledge data | |
| New-Age Tech / SaaS | High | Pre-IPO investors often entered at steep discounts. Pine Labs, Capillary Technologies in this category. Low profitability amplifies re-rating risk. | Volume spikes, GMP trend, institutional activity tab | |
| Renewable Energy | Moderate–High | Emmvee, Clean Max in this cohort. PE involvement is high but sector tailwinds provide natural demand absorbers. Still watch for concentrated block exits. | Order book updates, FII holding trend, anchor holding | |
| Logistics / Supply Chain | High | Shadowfax carries a large VC tranche. Logistics names often trade at thin margins, making valuation re-ratings sharper if supply floods in. | Promoter stake %, float utilization, delivery % | |
| Cement / Infra | Low–Moderate | JSW Cement has a large non-promoter block, but promoter group ownership remains dominant. Institutional ownership typically provides a natural floor. | Promoter holding %, DII buying trend, sector ETF flows | |
| SME Listings | Low | Lower institutional presence means PE exits are rarer. But thin liquidity means even small selling can move prices significantly. Borana Weaves example. | Daily volume, bid-ask spread, promoter lock-in date |
The NiftyTrader lock-in risk scorecard
Not every expiry is equally dangerous. A stock where 3% of equity unlocks — held mostly by promoters who have no intention of selling — is a very different situation from one where 55% of shares, mostly held by VC funds sitting on 4x returns, become eligible for trading on the same day. Use this scorecard to rank stocks on your watchlist before any lock-in date.

Rate each factor for the stock you are evaluating. Higher risk count = greater caution before entering.
Should you buy, wait, or exit? Use this before you decide
There is no single right answer when a stock approaches a lock-in expiry. Sometimes the selling is swift and sharp — a clean reset that creates a buying opportunity. Sometimes the supply overhang drags on for weeks as early investors systematically reduce positions. Work through this logic before you commit capital.
What to do before buying a post-expiry stock
If a stock you are watching has just crossed its lock-in expiry — or is about to — this is the sequence to follow before putting money in. Skipping even two or three of these steps is how retail investors get caught selling at a loss weeks later.
The bottom line
Lock-in expiry does not automatically mean a stock will fall. Promoters hold large chunks and often have no reason — or intention — to sell. Strong sectors attract institutional demand that absorbs supply without much drama. There have been plenty of cases where a stock rallied cleanly through its expiry window, because the underlying business gave buyers more confidence than the sellers had urgency.
But the risk is real, and it is asymmetric. A large, concentrated supply wave arriving without any fundamental catalyst can push a stock 10–20% lower before the market finds its feet. The Meesho lower circuit in January 2026 — five percent in a single session, triggered purely by a calendar date — is a reminder that this happens to quality companies too.
Over the next three months, $34 billion in IPO shares across 73 companies will enter the tradeable universe. Some of those companies will sail through. Others — particularly the consumer internet and VC-heavy tech names with unlock sizes exceeding 50% of equity — will face real tests. The investors who track these dates, understand who is selling and why, and wait for the supply to clear before committing fresh capital will consistently outperform those who are surprised by a perfectly predictable calendar event.
That is the entire point of market intelligence. The information was always there. The edge is in actually acting on it.
