MUMBAI: Markets regulator Sebi has proposed an overhaul of large IPOs (over Rs 5,000 crore), reducing the retail investor quota from 35% to 25% and raising institutional investor allocation to 60%. Retail participation has remained flat despite larger IPO sizes. SEBI also aims to increase anchor investor slots for allocations above Rs 250 crore to aid foreign portfolio investors. It proposed raising anchor reservations for insurers, pension funds, and mutual funds from 30% to 40%, with specific sub-quotas for each category.
