Indian equity benchmarks opened higher on Tuesday, with the Nifty 50 reclaiming the 25,250 mark amid positive cues from metals, IT and realty stocks. Broader market sentiment remains bullish with midcaps and smallcaps extending gains. Analysts expect a buy-on-dips strategy to remain effective as long as Nifty stays above 25,150. HCL Technologies shares gained 2% and RBL Bank rose 3%.
