The Indian stock market is set for a significant influx of shares as 83 newly-listed companies will have their lock-in periods expire between May and August this year, totaling approximately $55 billion in value. The first set of expiries began recently with 90 lakh shares of Deepak Builders & Engineers, valued at $8 million, and 7.4 crore shares of Afcons Infrastructure, worth $260 million. On May 8, 104.7 crore shares of Lenskart Solutions, valued at $5.6 billion, will become eligible for trade, following its muted debut last November. Other notable expiries include 418.2 crore shares of Groww-parent Billionbrains Garage Ventures on May 12, which are valued at $9.4 billion. While the total value of shares eligible for trade is substantial, analysts caution that not all will be sold, as many shares are retained by promoters and their groups. The market will witness further expiries from companies like Pine Labs and Niva Bupa Health Insurance throughout May and into the following months.
