The Indian equity benchmarks were trading with a negative bias on Wednesday on the back of selling pressure in heavyweights like Infosys, HCL Technologies, Tata Consultancy Services, ICICI Bank, ITC and Hindustan Unilever. The downfall was however capped owing to buying interest in Tata Steel, Axis Bank, HDFC and Larsen & Toubro. The Sensex fell as much as 169 points and Nifty 50 index touched an intraday low of 17,611.
