The Indian equity benchmarks fell for fourth straight session on Wednesday dragged by losses in index heavyweights like Infosys, Reliance Industries, Larsen & Toubro, ITC, Bajaj Finance and Hindustan Unilever. The Sensex fell as much as 846 points and the Nifty 50 index briefly dropped below its important psychological level of 16,000 at the day's lowest point. However, buying in banking and financial services shares helped benchmarks recover from intraday lows.
