Indian shares climbed higher for the fourth straight session Wednesday, led by pre-earnings buying in Reliance Industries Ltd. and banks ahead of corporate earnings announcements for January-March, reported AP. The Bombay Stock Exchange's 30-share Sensex index gained 81 points, or 0.6 percent, to 14,218 points. On the broader National Stock Exchange, the 50-company S&P Nifty index rose 26 points, or 0.6 percent, to end at 4,167 points. «It was a range-bound trading session with some short covering in the last hour,» said Sharmila Joshi, a dealer at Asit C. Mehta Investment Intermediaries. «Sentiment has also changed after the Reserve Bank of India left rates unchanged.» Banking shares rose on continued buying after the central bank Tuesday left key interest rates unchanged. HDFC Bank rose 1.7 percent to 1,032 rupees and ICICI Bank moved up 1.2 percent to 962 rupees. Reliance Industries gained 1.2 percent to 1,600 rupees on hopes of strong earnings.
