The Indian equity benchmarks slipped for second straight session on Thursday dragged by losses Reliance Industries, Bajaj Finance, Tata Steel, Maruti Suzuki and Larsen & Toubro. However, the downside was capped owing to buying interest in technology heavyweights like Infosys, Tata Consultancy Services and HCL Technologies. For most part of the day, the benchmarks traded in a narrow range as futures and option contracts for the month of December expired. The Sensex traded in a band of 431 points and Nifty 50 index touched an intraday high of 17,264 and low of 17,146.
