IRCTC (INDIAN RAILWAY CATERING & TOURISM CORPN Ltd) more than doubled on the first day of listing, the best debut for a local company since 2017, after its public float emerged as the most sought after for the nation’s state-run firms. Lured by IRCTC’s monopoly status, investor demand exceeded shares on offer by 112 times, eclipsing the government-owned Housing & Urban Development Corp. and Cochin Shipyard Ltd., whose maiden offerings were oversubscribed more than 75 times in 2017, a record year for Indian IPOs.
