IPO Lock-in Expiry Tracker

When anchor investor lock-in expires (30 days after listing), these institutional investors become free to sell their shares in the open market. This can lead to increased supply and potential downward pressure on stock price, especially if the stock has performed well since listing and anchors decide to book profits.

Use our lock-in expiry calculator above by entering the company name, listing date, and lock-in type. You can also check company announcements, red herring prospectus, or financial news websites. Many brokerage platforms also provide lock-in expiry calendars for tracking multiple IPOs.

It depends on your investment goals and the specific situation. If you're a short-term trader and the stock has performed well, you might consider booking profits before potential selling pressure. However, if you believe in the company's long-term prospects, temporary price weakness from lock-in expiry shouldn't change your investment thesis.

No, not all anchor investors sell immediately upon lock-in expiry. Many institutional investors have longer investment horizons and may hold positions if they believe in the company's growth prospects. However, some may choose to book profits, especially if the stock has performed exceptionally well since listing.

The price impact varies based on the size of anchor allocation, stock performance since listing, and market conditions. Typically, large anchor expiries (>10% of free float) can cause 5-15% price decline, while smaller expiries may have minimal impact. The effect is usually temporary, lasting a few days to weeks.

Yes, different categories of shareholders have different lock-in periods for the same IPO. Anchor investors have 30 days, pre-IPO shareholders typically have 1 year, promoters have 3 years, and employee stock options may have varying periods. This creates multiple unlock dates throughout the stock's post-listing journey.
