The Indian equity benchmarks snapped their five-day winning streak on Friday as investors booked profits at higher levels. The benchmarks staged a gap down opening with Sensex falling over 450 points and Nifty hitting an intraday low of 18,120. However, buying in heavyweights like Tata Consultancy Services, Infosys, HDFC Bank and Larsen & Toubro helped stage recovery in noon deals to close marginally lower.
