About $26 billion worth of shares across 71 recently listed companies will become eligible for sale between June 17 and September-end as IPO lock-ins expire, according to Nuvama Alternative & Quantitative Research. The lifting of these lock-ins could create a potential supply overhang for several stocks, said analysts. Of this, shares worth about $15.96 billion across 31 companies that mostly made their stock market debuts in the last six months are slated to become eligible for sale over the next month, said Nuvama Alternative's head Abhilash Pagaria. The list includes ICICI Prudential AMC, Vishal Mega Mart, Inventurus Knowledge Solutions, Sai Life Sciences, Nephrocare Health Services and Oswal Pumps.
