Indian equity benchmarks Sensex and Nifty opened higher on Tuesday, extending their recovery after Monday’s late rebound, following firm global cues. A sharp overnight plunge in crude oil prices eased inflation concerns and lifted global risk sentiment. At 09:30 am, the Sensex was up 445 points or 0.6 percent at 78,011, while the Nifty gained 135 points to 24,163. Market breadth remained firmly positive, with 2,399 shares advancing against 586 declines.
