Market update: Nifty tests 8100; Cairn, BHEL up

The 50-share Nifty index also managed to reclaim its crucial psychological level of 8100. The S&P BSE Sensex surged over 250 points in intraday trade after US index provider MSCI Inc, in a relief to Indian markets, said that it will hold off including China A shares in one of its key benchmarks, but expects them to be included once outstanding market accessibility issues are resolved.
