This is a critical heads-up for anyone holding these recently listed stocks. According to the latest data from Axis Securities, 11 companies are about to see a massive influx of shares hit the secondary market as their anchor investor lock-in periods expire.
When “lock-in” expires, it doesn’t mean anchor investors must sell, but they can—and often, this leads to a “supply overhang” that can temporarily drag down the stock price.
IPO Lock-in Expiry Calendar: April – May 2026
Here is the breakdown of the Rs 2,378 crore worth of shares set to be unlocked:
| Company Name | Expiry Date | Approx. Value (Rs Cr) | Type of Expiry |
| Sedemac Mechatronics | April 7, 2026 | 364 | 30-Day |
| Bharat Coking Coal | April 13, 2026 | 178 | 90-Day |
| Amagi Media Labs | April 18, 2026 | 366 | 90-Day |
| GSP Crop Science | April 18, 2026 | 127 | 30-Day |
| Shadowfax Technologies | April 22, 2026 | 397 | 30-Day |
| Central Mine Planning & Design | April 23, 2026 | 421 | 30-Day |
| Fractal Analytics | May 12, 2026 | 528 | 90-Day |

| PNGS Reva Diamond Jeweller | May 27, 2026 | 74 | 90-Day |
Why should you care?
-
The “Supply Pressure” Effect: If anchor investors decide to book profits (especially in stocks that have seen a post-listing rally), the sudden increase in available shares can cause the price to dip.
-
April Overload: April is particularly heavy, with over Rs 1,800 crore of the total value unlocking this month alone.
-
Big Movers: Keep a close eye on Fractal Analytics and Central Mine Planning, as they have the largest individual “unlock” values.
Pro-Tip: If you are a long-term investor, these dips can sometimes be a “buy the dip” opportunity. However, if you’re a short-term trader, you might want to watch the volume on these specific dates to avoid getting caught in a sell-off.
