Lock-In Period in IPOs: What Happens When It Ends?

1. Introduction: Why the Lock-In Period Matters

When a company goes public in NEPSE through an IPO, not all shareholders can sell their shares immediately. The lock-in period is a predetermined time during which certain shareholders—usually promoters, employees, or early investors—are restricted from selling their shares.

When this period ends, a large volume of shares may become available for trading, often influencing the stock’s price.


2. What Is the Lock-In Period?

The lock-in period is the duration after an IPO during which some shareholders are prohibited from selling their shares in the open market.

In NEPSE, SEBON (Securities Board of Nepal) sets lock-in guidelines to:

  • Ensure price stability after listing

  • Prevent massive sell-offs from insiders

  • Build investor confidence in the newly listed company


3. Who Is Affected by the Lock-In Period?

Typically, these groups have lock-in restrictions:

  • Promoter Shareholders – Often locked for 1–3 years

  • Employees (ESOP shares) – Usually locked for 1 year

  • Institutional Investors – May have shorter or custom lock-in terms depending on agreements

  • Anchor Investors – Sometimes locked for a few months post-IPO


4. Lock-In Period Rules in NEPSE

According to SEBON regulations:

  • Promoter shares are locked for at least 3 years in most cases.

  • In hydropower IPOs, promoters often have a 1-year lock-in from the listing date.

  • Employee quota shares typically have a 1-year lock-in.

  • Public issue shares for general investors usually have no lock-in (can sell after listing).


5. Why Lock-In Periods Exist

  1. Price Stability – Prevents promoters from cashing out immediately.

  2. Investor Confidence – Shows promoters are committed to the company’s long-term growth.

  3. Regulatory Compliance – Meets SEBON’s listing rules for fair trading.


6. What Happens When the Lock-In Ends?

When the lock-in expires:

  • A large number of shares may flood the market.

  • If many insiders sell, supply increases → possible price drop.

  • If insiders hold, it signals confidence, which may stabilize or boost the price.


7. How the End of Lock-In Impacts Stock Prices in NEPSE

7.1. Price Drop Scenario

  • Large promoter selling after lock-in expiry can push prices down sharply.

  • Common in overvalued IPO stocks.

7.2. Price Stability Scenario

  • If promoters don’t sell or sell gradually, the market absorbs the shares smoothly.

7.3. Price Rally Scenario

  • Rare, but if the company announces positive news at lock-in expiry, demand may rise.


8. Case Studies in NEPSE

Example 1: Hydropower Company

  • Lock-in expiry led to a 15% drop in 2 weeks as promoters sold aggressively.

Example 2: Banking Sector IPO

  • Lock-in ended, but no major selling → price remained stable and later rallied 8%.


9. How to Track Lock-In Expiry Dates

  1. NEPSE Announcements – Check company notices for lock-in expiry schedules.

  2. SEBON Prospectus – IPO documents list lock-in terms.

  3. Media Reports – Financial portals like Nepalytix provide reminders and analysis.


10. Investor Strategies for Lock-In Expiry

Before Expiry:

  • Watch for insider trading activity (buying or selling in advance).

  • Assess current market sentiment towards the stock.

On Expiry:

  • Expect higher volatility.

  • Avoid panic selling without assessing fundamentals.

After Expiry:

  • If the stock drops due to temporary selling pressure, it may be a buying opportunity.


11. Common Mistakes Investors Make

❌ Selling immediately without checking fundamentals.
❌ Ignoring the fact that some lock-in expiries have minimal impact.
❌ Buying just before expiry expecting a rally—high risk.


12. Combining Lock-In Analysis with Other Factors

Lock-in expiry analysis works best when combined with:

  • Earnings Reports – Strong results can offset selling pressure.

  • Sector Performance – A bullish sector can absorb extra supply.

  • Technical Indicators – Support and resistance levels help in timing trades.


13. 2025 Outlook for Lock-In Expiries in NEPSE

  • Expect multiple hydropower and microfinance companies’ promoter shares to unlock.

  • High retail participation may cushion price drops in strong companies.

  • Weak fundamentals will likely see sharper corrections.
