Several recently listed companies are set to witness lock-in expiries on June 17, 2026, making shares worth more than Rs. 20,000 crore eligible for trading.
Lock-in expiries are closely tracked by investors because they allow pre-IPO investors and other shareholders to sell their holdings in the open market. While the expiry does not necessarily mean that shareholders will sell, it increases the free float and can lead to higher volatility.
