Indian equity benchmarks BSE Sensex and NSE Nifty50 are likely to take a breather after reaching nearly one-month closing highs, mirroring a lacklustre trend across Asia following an overnight holiday on Wall Street. Singapore Exchange (SGX) futures — an early indicator of the Nifty index —declined as much as 67.5 points or 0.4 percent to 16,579.5 early on Tuesday, suggesting a muted opening ahead on Dalal Street.
