Investors anticipate substantial gains from recent IPOs hitting Dalal Street, judging by grey market premiums (GMP). Tata Technologies, with an 80% GMP at Rs 400-410, led with a 69 times subscription. Meanwhile, Indian Renewable Energy Development Agenc (IREDA) and Gandhar Oil Refineries command GMPs of around 30% and 45%, respectively. However, Fedbank Financial Services, despite a 2.2 times subscription, shows muted investor interest.
