The Indian equity benchmarks resumed their upmove after a day's pause on Friday led by gains in index heavyweights like Tata Consultancy Services, Reliance Industries, Infosys, Larsen & Toubro, UltraTech Cement and Maruti Suzuki. However, the upside was owing to weakness in HCL Technologies, HDFC Bank, Axis Bank, HDFC and Tech Mahindra. For most part of the day, the benchmarks traded in a choppy manner with Sensex moving in a band of 278 points and Nifty 50 index touching an intraday high of 18,321 and low of 18,228.
