India, Nov. 9 -- Indian equity markets gave up their opening gains on Monday, with benchmark indices trading lower as investors booked profits following a sharp rally last week. The decline pushed the Nifty below the 25,000 mark, while losses in major information technology stocks weighed on the Sensex.

The 30-share BSE Sensex fell 93.95 points, or 0.12%, to 80,919.19 in early trade. The NSE Nifty 50 declined 30 points to 24,968.80. Among the Sensex constituents, HCL Technologies, Infosys, Power Grid, Bharti Airtel, UltraTech Cement and Tata Consultancy Services were among the major losers. On the other hand, State Bank of India, HDFC Bank, ICICI Bank and InterGlobe Aviation were among the stocks trading higher.
