A couple of listed stocks tell the story of the mayhem in the Indian stock market, currently in the grip of a global pandemic. Last October, the IPO of the state-owned monopoly, Indian Railway Catering and Tourism Corporation (IRCTC), listed at twice its offer price of Rs 320. By February-end 2020, it peaked to almost Rs 2,000. But by March 17, it tumbled nearly 50 per cent. Recently, investors expected SBI Cards and Payment Services to list at a premium to its offer price of Rs 750. It didn’t. On March 16, it closed its first day with a loss of 9 per cent.
