The grey market premium (GMP) for online investment platform Groww has crashed by nearly 70%, slipping from Rs 16 at its peak to around Rs 5 ahead of its listing. This translates into a modest 5% premium over the IPO price of Rs 402 per share, signaling that investor sentiment toward IPO remains cautious especially after a weak listing of Lenskart. However, analysts expect the company to deliver a modest listing gain of 5-10%.
