The Indian equity benchmarks snapped their two-day winning streak led by losses in index heavyweights like Reliance Industries, ICICI Bank, Infosys, ITC, HDFC Bank and HDFC. The benchmarks staged a gap down opening taking cues from subdued trend in Asian markets and extended selloff in noon deals after selling pressure engulfed European markets. The Sensex fell as much as 792 points and Nifty 50 index briefly dropped below its important psychological level of 15,400.
