Indian equity benchmarks BSE Sensex and NSE Nifty50 are likely to make a gap-up opening on Thursday tracking strength across global markets, as investors overlooked hawkish remarks made by Fed officials. Singapore Exchange (SGX) Nifty futures — an early indicator of the Nifty index — rose as much as 131.5 points or 0.7 percent to 17,762 ahead of the opening bell on Dalal Street.
