India’s biggest stock exchange is keen to buy a 25 percent stake in Dhaka Stock Exchange, rivaling an offer from a Chinese bourse. “We are well positioned to help grow the Bangladesh market and the exchange, given our experience and track record,” Vikram Limaye, chief executive officer of the National Stock Exchange, said in a phone interview on Thursday. The Shenzhen Stock Exchange has offered 22 taka per share to buy 25 percent of the Dhaka Stock Exchange, Rakibur Rahman, a director at the DSE, said by phone last week.
