Mumbai: The benchmark Sensex jumped over 90 points in early trade today, extending yesterday’s gains, on the back of increased buying by participants as the country’s infrastructure growth hit a 6-month high in May. Besides, a firming trend overseas kept the momentum going. The 30-share index, which had gained over 135 points in the previous session, rose 90.47 points, or 0.33 per cent, to 27.871.30, with all sectoral indices led by consumer durables, healthcare and realty trading in the positive zone with gains up to 1.08 per cent. The NSE Nifty also inched higher by 17.30 points, or 0.21 per cent, to 8,385.80. Brokers said sentiment got a lift after the output of eight infrastructure sectors expanded 4.4 per cent in May, the highest growth rate in the past six months and a hardening trend in the global market despite Greece’s default. Among other Asian markets, Japan’s Nikkei rose 0.22 per cent in early trade today, shrugging off the Greek default. Financial markets in Hong Kong are closed today. The US Dow Jones Industrial Average closed 0.13 per cent higher in yesterday’s trade.
