MUMBAI (Reuters) - The BSE Sensex fell on Friday as caution ahead of a key inflation report next week that will help determine the outlook for interest rates hit lenders such as State Bank of India and spurred profit-taking in recent outperformers such as ONGC.
However, Infosys, India's second-biggest software exporter, surged 16.8 percent, its biggest ever daily percentage gain on the more actively traded National Stock Exchange, after reporting stronger-than-expected earnings and raising its annual revenue forecast.
