Reliance Industries Ltd, Infosys Ltd and HDFC Bank Ltd are among the firms that call both the National Stock Exchange of India Ltd and BSE Ltd home. When the Indonesia Stock Exchange halted trading because of a glitch on the same day as NSE, there was zero trading in stocks and equity derivatives nationwide. The same was true in Singapore in July 2016, when the local exchange suspended stock trading because of a hard disk failure. Having a dozen venues means a halt at a stock’s home exchange doesn’t necessarily suspend trading across the entire market. The dual listings don’t help in India’s derivatives market, where contracts are specific to a particular exchange and the NSE’s dominance is greater than with cash equities.
