Mumbai, Sept 17 :     The Over The Counter Exchange of India (OTCEI) announced two initiatives today that would enable the exchange to play a major role in the market for initial public offers and create fresh opportunities for new companies, especially in the information technology sector. OTCEI managing director J.H. Bosco said the exchange had initiated steps to form a subsidiary to take up the membership of National Stock Exchange, enabling its member broker to gain access as sub-brokers to NSE?s members. Bosco said the subsidiary is expected to become an NSE member in three or four months. As part of a drive towards initiating more investor-friendly measures, the exchange?s market making rules will also be completely revamped to create greater liquidity for stocks listed on the OTCEI and provide more exit opportunities for the investors at all stages.
