As March winds down, the focus of IPO investors shifts to the upcoming month, where a fresh wave of anchor lock-in expiries is expected to impact trading sentiment. In April 2025, five IPOs will witness the end of their anchor investor lock-in period, potentially unlocking shares worth INR 346.82 crore.

A Look Back at March
The relatively low number of IPOs facing anchor lock-in expiry in April can be attributed to zero IPO listings in March 2025. The absence of fresh public issues in March means fewer upcoming lock-in expiries, since anchor investors typically face a 30-day to 90-day lock-in period post-allotment.
Why Were There No IPOs in March?
Several factors contributed to the dry spell in March:
- Market Volatility: Global macroeconomic uncertainty and domestic equity market fluctuations made it difficult for companies to price their issues attractively.
- SEBI’s Regulatory Tightening: Recent compliance and disclosure norms introduced by SEBI have increased scrutiny and lengthened approval timelines.
- Heavy Selling by FIIs: March witnessed intense selling pressure from FIIs, who pulled out funds from Indian equities amid global risk aversion. Their exit further spooked markets and weakened the demand environment for new listings.
- Subdued Investor Sentiment: Weak listing gains of prior IPOs and declining oversubscription levels may have discouraged new entrants from hitting the market.
While these unlockings may not match the scale of March’s figures, they could still have localized effects on specific counters, especially in the small and mid-cap segment. Investors should remain alert, as the release of a significant number of shares may lead to short-term selling pressure.

Understanding the Impact of Anchor Lock-in Expiry
When an IPO is launched, a portion of shares is allotted to anchor investors—typically institutional players like mutual funds, insurance companies, and other large entities—just before the issue opens for retail and other investors.
These anchor shares are subject to a lock-in period, often 30, 90, or 180 days, after which these investors are free to exit their positions. Historically, this leads to increased market supply, which can temporarily affect the stock price if demand does not match the selling activity.
However, strong fundamentals often help quality IPOs recover swiftly. The post-lock-in phase also acts as a litmus test for market confidence.
Key Effects of Anchor Lock-in Expiry
- Surge in Share Supply: Increased float can put pressure on stock prices, particularly if several large investors decide to exit.
- Price Volatility: Stocks may experience sudden dips or spikes depending on trading sentiment and demand.
- Market Sentiment Indicator: Continued holding by institutional investors after lock-in expiry is often a bullish signal.
- Entry Point for Investors: A dip due to selling may offer long-term investors a value-buying opportunity.
Investment Strategies for Lock-in Expiry in April
- Track Volumes: Unusual spikes may suggest anchor exits.
- Analyze Fundamentals: Stocks with solid earnings and business models tend to hold up better under selling pressure.
- Wait for Dips: Post-lock-in dips, if any, could offer lucrative entry points for long-term portfolios.
- Avoid Herd Mentality: Not all lock-in expiries lead to sharp falls—evaluate stock-wise.
- Diversify Holdings: Spread exposure to reduce risks from individual stock volatility.

Final Thoughts
April may not bring the same intensity of anchor unlockings as March, but INR 346.82 crore worth of shares entering the secondary market is still noteworthy. The lack of IPOs in March means fewer lock-in expiry in April, but the upcoming months may see more action if market conditions stabilize.
As always, investors should focus on the quality of the business, institutional behavior, and price action during this critical phase. Long-term opportunities often emerge when short-term volatility clouds judgment.
