AlQa'dah 5, 1433, Sep 21, 2012, SPA -- India's stock markets posted over 2 per cent gains early Friday, buoyed by the government's decision to relax the rules governing foreign investment in local businesses, dpa reported. The government late Thursday announced its decision to allow more foreign direct investment in the retail, aviation and broadcasting sectors, ignoring widespread protests by opposition parties and some of its own allies. The benchmark 30-share Sensex index on the Bombay Stock Exchange reached 18,804.29 by late morning trade, about 2.48 per cent higher than Thursday's close. The broader 50-share S&P CNX Nifty on the National Stock Exchange jumped by 2.61 per cent in the same time, led by gains in capital goods, power, banks and realty stocks. Stocks of Indian retail and aviation companies posted major gains.
